Fan suggestion X1950XT

[x800professor]

How much is the northbridge fan protruding over the motherboard though? It looks like a tight fit.

It wouldn't fit in the upwards position because of that nb fan. Upwards should be the better position too. Back to the x2 vs vf900cu again. The vf900 is winning in the poll.

 

[tkpenalty]

But half the people just know Zalman and don't know much about AC.

AcceleroX2 will cool the memory better than the VF900 CU.

 

[lufrey]

There should be plenty of room.

Hmm, I don't think you have enough room to put the X2 in there.

 

[tkpenalty]

Hmm, I don't think you have enough room to put the X2 in there.

Um yeah.... wtf? The X2 isnt vertical. We WERE mentioning about the Thermalright HR-03.

He did the measurements and it will fit, barely breezing the 25cm fan.

Just my observation mate, relax. I've never held an X2, but the pics of it look rather large to me. If it fits, it will be tight.

Actually I haven't done any real measurements yet. It's about 4.7 inches wide at its widest part. I'm going to have to get a tape measure down there (which I don't have one in the apartment right now) and figure out exactly how much room I have. The bottom of the fan just barely intersects the card. However, my motherboard (EVGA 680i) has 3 PCI-E x16 (physically) and 2 PCI-E x16 (electronically) slots, so I could just move it down to the second full x16 slots, which is below the fan.

Look at the picture of the opened up Accelero X2. Work out how the air is being forced (flows) from the fan unit:

>> The direction of those cooling fins is horribly suboptimal. A huge turnulence is being created inside the plastic case... and the air "flow direction" has to literally go round a corner to get into one of the fin channels and out.

>> The design is suboptimal... it will make more noise and cool less that a SIMILAR DESIGN with fins in a better direction. Just take a look at the STOCK X1950XT to look a more optimised airflow.

>> I would not be surprised to see the Zalman cooling better due to the unrestricted airflow... and fin direction optimised for flow of air.

>> Accelero X3 needs to fix this design flaw. In the meantime I suggest anyone with an X2 opens it up and manually adjusts the direction of the internal cooling fins to improve its performance

Eh, mine works just fine, and is almost completely silent. Design flaws or not, it just works. It could work better perhaps, but at $20, I'm not going to complain. The money I saved going with the X2 allowed me to buy a couple more case fans, which provided better OVERALL system cooling.

Completely Bonkers sometimes makes the most weird posts. Doesn't matter if its pointing towards the Motherboard, its cheap and efficient and on par with the ultra-expensive VF900-CU.

How many times have you used the word "suboptimal"? You think using those words will be persuasive right?

The Accelero was designed like that for a reason, to remove heat from the GPU, unlike the VF900 that blows the air onto the PCB. In the short term, its okay... BUT in the long term faliure is bound to be happen sooner.

The stock X1950XT cooler's design is suboptimal it blows in air, probably exausted or acculmulated hot air.

You must be on pot or something if you think the X1950XT's cooler is better. That cooling design is so inneficient

The Accelero's cooler's fins aren't obstructive! If you don't know how its made/looks like, then don't make up FUD. I feel a gust of warm air from the fins! That fan is designed to blow... SIDEWAYS. Its desinged like that to accomodate the zero-friction fan, the fan is on a silicone mount which eliminates any vibration (thats if the fan will actually produce any). Reports of people destroying their graphics cards through installation of this are just some dumbfucks who don't read the instruction manual.

that goes for you as well, your ax2 spreds heat from ram chip to ram chip as well as from gpu core to ram/ram to core due to design, the vf900 cools the whole card with that air blowing on the pcb, i havent ever felt more then barly warm air come off my card even at 700/1700(850) the ram sinks where barly warm as well, the air blowing over the card also cools other componants that dont get cooled by coolers like the x2, some of them get a bit warm normaly, nothing insain but they do still get warm.

and ultra expencive please, u want ultra expencive.....

check that thermaltake water cooler, cant remmber what its called but it was around 80bucks last time i looked(that was on sale with rabates!!!)

the vf900cu is 36bucks(aprox) i got mine for 28(sale) and its all copper.

the vf900cu led versions overpriced, thats a given anything with lightes is overpriced

u want the cheepest decent cooler that will work on these cards
http://www.newegg.com/Product/Product.asp?Item=N82E16835124006
its not new, its not "pretty" but its 15bucks and can do the job quite well, and it blows freshair over the cooler+card...... wouldnt be my top choice but cheap for cheap these kind of coolers are the best deal.

want pricy

http://www.xoxide.com/thermaltake-tmg-at2-cooler.html

http://www.xoxide.com/thermaltake-tmg-at1-cooler.html

i did install one of these
http://www.xoxide.com/logisys-dual-heatpipe-vga-cooler.html
on an x1900gt(rev1) that was 16pipe enabled, added some diffrent ramsinks(zalman aluminum ones) and the card was running at a max temp of 67c

i acctualy kinda like those tt coolers, but meh, i would probbly just get heatpipe cooler and throw on a good flow fan if i was looking for cheap...or in my other case where i got an 80mm fan blowing dirrectly at the videocard (thats why my x800xt pe has a first gen zalman heatpipe on it

 

[tkpenalty]

Um... wtf? I don't get what you are trying to say. X2 does cool VRMs if you haven't noticed, with a side blow-off vent before the heatpipe-contrapment. The AcceleroX2's aluminium/copper base asorbs heat really quickly through the heatpipes, thats why you find the AcceleroX2 users having better memory overclocks.

 

[AshenSugar]

=D, nice results.

Ashen all because I am fourteen you don't have to act like a jerk to me, seriously, you are being rather immature for your age. Whats with your age "Superiority complex" that you have? It just proves how short-sighted you are.
Ashen, you live in the USA, learn how to type english without any speeeeling mistakes.

The thermalright HR-03 MAY fit, but with such a beast of a CPU cooler, I have doubts. If you can find it, try getting it. AcceleroX2 shines with a good amount of heat removal around the GPU. For the VF900 it means almost nothing.

just bothered to read this, and a note for you, your acting like a zelot fanboi, you havent used a vf900 but ur all down on it calling it shit and such, every time somebody posts reccomending it you post calling it shit, how mature is that?

 

[tkpenalty]

Hey dude no personal insults okay? Mr IAMSUPERIORBECAUSEIAMOLDER.

VF900 is good but Accelero in the long term is better, price and noise output.

 

[AshenSugar]

the vrm's are cooled by any cooler that blows air over the card, the x2's design dosnt lend to it efficently cooling the vrms since it blows AWAY FROM THEM as bonkers tryed to say, the design is far from optimal for airflow.

it has to flow around a corner to get to the VRM's and the back side of the heatsink.

im not saying it dosnt work well,but i have installed them, and they are far bulkyer then the vf900, and if properly installed they dont cool any better, but the x2 blows all the heat removed from the card(gpu/mem) down onto ur mobo, and in the case of most current boards the chipset placement means the heat is gonna be shared far more dirrectly with the chipset then it would with the vf900, its just a fact of the new design ac tryed with the x1/x2 coolers, their coolers of the past where better designs that moved the heat dirrectly out of the case(ice q3 is the next evolution of that)

if i want i can find posts of people saying how much the x2 sucks, just like you tryed to do with the vf900, infact i will just for you since that seems to be what you need to see.......

The instalation of Accelero X2 on a X1900XT card significantly raises my chipset temperature (DFI Lanparty NF4 Ultra-D, but it will affect any motherboards with similar northbridge placement). The difference compared to stock cooling is about +10C, so the norbridge fan actually spins up to 100% to keep northbridge under 60C.

thats about right, nice chipset temp boost there, corse that dosnt matter to you

Yep yep, had that all setup in ATI Tool. The X2 just didn't cool worth a crap under a load like Oblivion. It was fine in non-3D loads, better than the stock cooler in fact.

So I did the little ghetto mod to the cooler, here's the space I cleared out of the HSF and fan housings

oh and another review showing the vf900 outdoing the x2.

http://www.vadim.co.uk/articles/Battle_of_the_High_End_VGA_Coolers

This week we have taken two very highly rated air cooling systems for graphics and put them to the test up against a stock cooling unit. The graphics card in questing being the mighty Sapphire ATI X1900XT 512. The coolers that were put to the test along with the stock cooling unit were the Arctic Cooling Accelero X2 and the Zalman VF900-CU.

The first device was the stock cooler that comes with the card. The first impressions of this cooling unit is that it may just have the edge over specialised air coolers due partly to its reasonable sized heat sink and an equally reasonable sized fan. So the big question is would the cooling unit prove to be sufficient in keeping this beast of a graphics card cool under a high load? ........................NO!
So what exactly are the reasons for such poor performance? Quite clearly the cooling unit is lacking the capacity to absorb enough heat to allow for effective heat dissipation. The cooling fan does not seem to have the ability to blow enough air through the heat sink which is a major draw back. However the fan is not as bad as the results will have you believe as a high amount of hot air blows out through the grill on the card. Initially when the system powers up the cooling fan starts spinning at a fast rate then slows down to almost being un-noticeable, which may be one of the factors in its high temperatures. However not all can be blamed on the heat sink and fan alone. The thick plastic cover seems to work against the fan and heat sink by helping to retain the heat generated by the card.


The next unit that we tested was the Arctic Cooling Accelero X2. The first impressions had me convinced of its ability. This unit has a very large heat sink, which boasts a copper core for the GPU and uses heat pipe technology to move heat away from the cards components. To blow heat away from the heat sink is a fan which uses a fluid dynamic bearing to allow for higher RPMs while keeping the noise level to a minimum. The Accelero X2 also comes with a nice little feature in that it already has thermal grease pre-applied, which makes things much easier and cuts out the messy task of doing it yourself. 8 Additional heat pads are also supplied with the unit. To attach this cooler to graphics card is a very straight forward process which only takes a couple of minutes to do and looks like so:

As the results show the Accelero X2 is more effective than the stock cooling unit, however the difference is so marginal that it begs the question why? On first impression it would appear that cooler is lacking in something. It would be easy to blame the fan for how quiet it is, but this is deceiving as it draws a nice amount of air into the unit. The Accelero X2 is a good cooler with one simple flaw. The only place for the hot air to escape is downwards straight on to the base of the card. It is highly possible that this is having an adverse effect on the card.

The final cooling unit that we put to the test was the Zalman V900-CU. And just looking at this cooling unit, you somehow know that this is going to be something special. This unit has a nice and smooth copper contact patch for the GPU and uses heat pipes which are surrounded by copper fins for a maximum surface area. In the centre of all this copper is an 80mm 2 bearing fan. The cool thing about this cooler is that it comes with a controller so depending on what you are doing you can adjust it to run at anywhere between 7 and 12 volts. The 7 volt setting is incredibly silent and the 12 volt setting is quite enough to be un-noticeable. The cooler also comes with 8 small heat sinks which are used to provide heat relief to the graphics memory. The installation of this unit is very easy and straight forward. Once installed it looks rather cool as the pictures below shows.

The Zalman cooler is a light weight unit and as a result doesn’t exert much force on the card itself. The results clearly indicate that the Zalman has the edge over the others with both low and high speeds on the fan. This is truly a great cooling unit and if you are of the opinion that a computer not only has to look good but perform equally well then this is a must.
The results gained from our tests are shown below:
So in the end what conclusions can be drawn from this? It would be unfair to write off the other coolers and just go for the Zalman V900-CU. Arctic Cooling’s Accelero X2 is a good cooler and in a nicely ventilated case there is no doubt that it would do the job and do it well. As for the stock cooling unit, it is almost there and with a couple of adjustments it would give the other coolers a run for their money. On the day the Zalman V900-CU proved itself as the most outstanding candidate for the job, however with the competition in the gaming market heating up it can only mean good things are on the way for cooling. The future seems bright and we will be there to see just how the next generation of coolers perform.

take a look at the full review for pix of each cooler, they didnt say it sucks but they did say its not really much better then the stock cooler.

Hey dude no personal insults okay? Mr IAMSUPERIORBECAUSEIAMOLDER.

VF900 is good but Accelero in the long term is better, price and noise output.

as stated above, thats you OPPENION, you state it as fact, when clearly its not, you THINK/BELIVE its better, just because of that you post over and over telling anybody who dissagrees they are wrong and treating them like they are stupid for not seeing how wrong they are, i didnt personaly insult you, i just stated my oppenion about how YOU are acting, i know i can be a bit abracive, guess what, thats my right, its also my right to disspute your FUD, you know like the FUD you posted about the vf900 being Heavyer then the x2 when it is acctuly what 75g lighter?(or was it more?)

as i said in a preivous post, u and i should just stop posting on this topic, let him make up his own mind between the x2 that heats up ur board/chipset and weighs more, or the vf900 that is lighter and dosnt have a notable impact on chipset/board temps.

now lets just agree to dissagree and stop with the link war of whos right, he will choose what he chooses and what looks best to him, we have bouth stated our cases, over and over, as have others, now its time to let him deside.

thats about right, nice chipset temp boost there, corse that dosnt matter to you

I'm gonna chime in here again, just because they saw 10*C jump in chipset temps, doesn't mean everyone will. Mine are only up 2-3* on average, sometime 5* at peak. If those kind of temps are gonna cause problems, then you needed better case flow or chipset cooling to begin with. The Zalman also causes more heat to be in your case, so this is a moot point. Both blow in the case, both raise temps, period. I'm not saying either of them are bad coolers, but my money was better spent on the X2 with the leftover going to case fans.

 

[AshenSugar]

with myzalman the heat dosnt get to my chipset(right at the back of the pci-e slot) because the case fans blow the heat away from the card and out the open card slots, with the side on i can acctuly even get more cooling and drop the mobo and video temps a bit due to the way the 80mm fan on the side of the case blows the air.

really i would have liked a silencer style cooler insted of vf900 or x2(x2 was acctualy made with BTX formfactor in mind, due to everything being reverced the heat would go up and be blown out the back of the case by the crossflow)

and if u get 10c extra on ur chipset and it causes problems, well i think thats a bad thing, most boards today seem to be comming with sub optimal chipset cooling, like asus and their crappy passive heatpipes(think gigabyte and abit do that crap to now days) and my buddys msi board has a passive cooler, sure it would be good to replace that b4 installing a board, but who wants to have to pull a mobo and swap a chipset cooler? i have and its a pain in most cases.

and yes many people would see less then 10c, but some would see more then 10c temp boost due to chipset cooling, i can guarntee if i was using stock cooling on this chipset that would push the board to the point where it was unstable, its not a cheap board, 147$ board on newegg, 157 localy, i agree, that having good case airflow is important, but so is not dirrecting a heatblower at heat sencitive parts, why not just stick a box heater next to ur pc

Well, your explanation may have nabbed the difference in my setup versus others, I'm reverse ATX. I didn't even consider that. But that also proves that the X2's performance varies wildly depending on your personal configuration. With his 25cm side fan, I really don't think chipset heat will be an issue for him.

How many times have you used the word "suboptimal"?

I used the word twice. Sorry to see you have had a difficulty counting into those dizzy digits. Most people on this forum are good at maths. But I'm happy to help

I not sure if you understand the word suboptimal, or don't have a dictionary, or have a dictionary and can't find the word in it. But suboptimal means that the design is not achieving the most desirable possible effect. And this is exactly the issue with the Accelero.

I did not say it doesnt work.. or that it is rubbish... or that I wouldn't recommend it. But there are some very obvious improvements. And I stated them. And most people would be able to understand them.

I know fluid dynamics is beyond the school physics course you are studying at school.. but I would advise you not to so actively voice your lack of knowledge or otherwise people will down-rate their impression of what you have got to contribute on this forum. If you find time to read a book on fluid dynamics at the weekend then you'll learn a lot... And you can come back and share some of the insights with us on this forum. We'll gladly listen to informed, scientific, knowledge.

How bad is the stock cooling on the card?
I'm looking at buying a Sapphire x1950xt.
I have good air flow, will even be better with the new case.
And I wont be overclocking it at all. Not worried about noise..

But is it running hot? I don't like my video getting much over 70-75c..

 

[AshenSugar]

stock at minimum needs taken off and the core contact lapped, it in most cases is a VERY ruff contact point(ffar from smooth)

if ur not gonna overclock then u shouldnt "need" 3rd party cooling, just lap the core contact and use some asc(ceramiq) and u should be set, u may want to use atitool or the like to turn the fan up a bit, at full tilt its a bit loud tho, but i can cool as well as any current 3rd party air cooler if you use it at full fan, again it gets VERY loud at 100%

 

[tkpenalty]

^Hey dude learn how to type properly and not like some drunken hick person.

Sorta biast but true reason why they didn't use the DHES:

DHES (Direct Heat Exhaust System)
A DHES doesn't make sense for a quiet high performance PC . The 1 C plus in ambient temperature doesn't matter since it is easy to cool nowadays CPUs quietly - but it is very difficult to cool a high performance GPU virtually silent. Therefore air should be drawn directly from outside to the VGA cooler, basically exactly the opposite of a DHES. The Accelero outperforms all competitors and offers a 13 C better cooling performance o*n a X1900XT board compared to the stock cooler (dynamic fan speed) at a far lower noise level. This is possible because we rejected the DHES.
Advantage of DHES: Reduces the computer ambient temperature by about 1 C.
Disadvantage of DHES: A lot more pressure is used. Therefore the fan generates a far higher noise level at the same performance.
The exhaust air of about 35-40 C is no problem for the mainboard. All components are specified for at least 85 C or more and therefore if these components run hot, the air stream works as a cooling. Compare to the P4 cooling, where the exhaust air is also used as a cooling. The warm air arise automatically in the PC case and will be blown out by the case fans.

Have you ever wondered why 5000RPM fans sometimes sound like F1s?

Okay, first off Ashen, you are so short sighted, that review (link please?) They probably were using a motherboard which had irregular NB Placements. With the EVGA 680i I don't see an issue with heat.

AcceleroX2 does better in a better case (which X800Professor has).

 

[Pinchy]

notice how they tell us how 'crappy' DHES is NOW once they have scrapped it

2 years ago it was the best thing since slice bread

 

[tkpenalty]

Yeah... DHES is sorta noisy, they aren't going its crap but not such a great idea for a "quiet" system. DHES on the X850XT series should be called DNGS "Direct Noise Generator Source" though.

 

[AshenSugar]

now whos being a dick? calling me a hick makes u a dick:O

and DHES wouldnt be any louder then the x2 is now where they to use the same fan, the noise comes form the type of fan used, there are many ways to move air that dont make alot of noise.
i did link to the forums where the 10c was posted.

i would say your short sited as well, your x2 is only good for cards of the past, vf900 can work on pretty much any card u get, even next gen cards due to its design.

and FYI there is not standred chipset placment, most boards of today put the chipset dirrectly behind the primary pci-e(videocard) slot, this means the heat from you x2 is blowing dirrectly at the chipset, your board may not have an issue, but your boards not the only one out there, your personaly exp isnt the end all and be all of the computing world, since you cant take my sujestion that we stop this post war over whos right and whos wrong i guess i gotta keep posting to counter your stream of bias fud on this subject, had you used/owned/tested a vf900cu dirrectly vs a x2 your self that would be diffrent, but you havent you just keep posting "its better because its got heat pipes" or "its better because itts cheaper" or "its better because it cools the ram to" or "its better because it cools the vrm's" or "its better because its silent" when at any distance over 3inches from the fan the vf900 is slient as well. fact is the coolers are bouth better then the stock.

i have installed bouth, the x2 is bulkyer+heavyer and in my exp isnt any better then the vf900 and blows all the heat removed from the card down at the board/chipset/cards below it.

the vf900 is LIGHT, cools every componant on the chip side of the card, blows the heat it dissapates in all dirrections and dosnt chanil it at the board/chipset/lower cards, dosnt cause memory chips to share heat with eachother(each has its own sink, included with the kit) cools the WHOLE vrm heatsink not just a small part of it(x2 blows hot air on a small portion of the vrm sink)
and if you deside to buy a new card later and sell the one you have or use it as a PPU you can stick the stock cooler back on, and use the vf900 on ur next card, because its not spicificly made for 1 model of card.

as i have stated, the vf900 is silent unless ur ears against it, sames true with the x2 honestly if u run it at full tilt its silent unless ur got ur head next to the fan, eahter way if u got ur case side on u cant hear eather of them full tilt, ur cpu cooler or case fans or even chipset fan (if its a stock chipset fan) will alwase be louder then a 3rd party cooler u add, the stock x19*0 refrance cooler at 100% will alwase be as loud as a hairdryer.
