Oh ok, I gotcha now. We are talking feature wise and all the different settings and stuff that another high end AM3 board lacks.

 

[Hunt3r]

Chicken Patty..Maybe yeah..the only problem is that next year will leave the processor

 

[Chicken Patty]

So it will be released next year? Sorry bro I didn't understand your last post.

 

[Hunt3r]

will it have much of a difference the 975 with 965

 

[Chicken Patty]

I hope so. If it's 125W most lowly it'll be clocked at 3.6GHz with the same voltage as the 965 which is clocked at 3.4GHz. That sounds promising.

 

[Hunt3r]

That should be interesting to see. So let's say it clocks at 3.6 GHz, but the voltage is the same as the 965, 1.392v? That would be promising.



For case and HSF I use these, they work great. Maybe for HSF there are better choices, but these are the ones I have had experience with and they are very good.

More on overclocking do not think it'll be nice not the TDP it does not worsen the situation

 

[Chicken Patty]

Well generally a CPU that can keep a TDP thesame at higher clocks should overclock better and cooler as it should use less voltage.

 

[Hunt3r]

The motherboard is very helpful in extreme overclocking..i think.hehe

 

[Chicken Patty]

Of course a good mobo helps. It's like having a powerful car with a bad clutch. You can't use all of it power.

VERY good simple description of the CPU/motherboard relationship!

 

[Chicken Patty]

Thank you Paul. Been through that with cars before, I'm speaking from experience ;

Fan comparison and results

you need fans with greater air pressure,as you say!
the only one i know,that can push even thru the tightest Rad Fins (my mega rad, for example) are Enermax Magma, even tho their Bearings tend to break, if you stick your fingers in them too often. tested it myself.
theyre quiet also, only the sound of rushing air is to be heard

Thanks for the recommendation Velvet, I'll look into those fans.

Scythe 120x25mm SlipStream SY1225SL12SH - 110 CFM

CP, you already know that I have the same Scythe as you do, and I was going to test the difference between the stock V8 fan and the Scythe 110cfm.

Well I finally swapped the fans back over last night (also did a touchup to the lapping job...I got tired the night before lol), and the rig is up and running again. After finally testing the two fans on the lapped V8 heatsink I have to say that HANDS DOWN the original V8 fan is superior to the 110cfm Scythe.

The Scythe has a more angled blade design with larger spacing between the blades in comparison to the V8 fan. The V8 fan has a much much more sweeping curve design to the blades, and a visually noticable smaller gap between blades. Both fans have 9 blade setups with the largest difference being the blade layout itself. The V8 is rated for 66.7cfm at top speed of ~1800+ rpm, the Scythe is rated for 110.3cfm at top speed of ~1900rpm. Putting a hand behind either fan shows the V8 fan having a totally different feeling/suction compared to the Scythe. Noise levels are obviously larger on the Scythe due to the different design of the fan.

Loading up 3.8Ghz @ 1.392v using both setups shows the idle temps for the Scythe roughly 30-31C which is excellent of course. Temps for the V8 fan are roughly 27-28C with the fan on it's lowest speed setting of ~1400rpm. The more important and direct comparison is the load temps between the two fans at this setting.

V8 temps = 42-43C
Scythe temps = 43-44C

Of course those temps are very close to each other, however the picture becomes much clearer when you know that..........The V8 fan is still spinning at it's slowest speed (fan controller locked on low), the Scythe is spinning near it's top speed at ~1670rpm or better. Again adding to the result is that the Scythe fan was able to have the V8 fan blowing out the case exhaust, while for the V8 test I only installed a super silent (10dBA) 40cfm 800rpm fan! Another thing not shown by the final temps is the fact that the V8 fan setup stayed at 41-42C for nearly the whole test only reaching 42-43C for a small amount of time near the end of the test, it also went up very very very slowly through the temp range. The Scythe went almost instantly to 44-45C then then began to level out in the 43-44C range.

The room was also a couple degrees warmer (other system components had higher temps as well due to this) during the V8 test making it an even better result.

So yea, in the end the V8 fan is superior to the Scythe fan for the purpose of blowing through the heatsink fins. As a case intake fan I imagine the Scythe would leave it for dead no problem. Once you introduce a restriction in front of the Scythe however the tables turn quite dramatically. The V8 is also a far more pleasing sound to listen to when it's on it's highest setting in comparison to the Scythe which is just plain old loud!

While not literally the same fan as the stock V8 fan it looks 99% the same, and the specs (except this has a higher rpm than stock V8) are very close as well. The color is different than the stock V8 fan as well, but look at the pictures of the fan when not rotating to see the design.

SCYTHE FAN DESIGN
http://www.newegg.com/Product/Product.aspx?Item=N82E16835185060

Both fans have a VERY different design goal which is obvious from the pictures, if buying for the purpose of a heatsink/radiator then I easily say buy the Cooler Master. If for a case fan then I say go with the Scythe.

Hope this helps guys...now I need to figure out what I'm going to do about getting some Gentle Typhoons.

Just passed wPrime 1024M finally 3.9Ghz @ 1.440v. Max temp was only 45-46C with the V8 fan still locked on the lowest setting. That's a roughly 2-3C increase in load temp over the 3.8Ghz @ 1.392v clock. I'm curious to see what increase the 4Ghz clock brings if I can get that stable enough to pass the full 1024M test. Since the temps are so low I may try the 3.8/3.9Ghz clocks again later with lower voltages to see if they're stable. These temps are all the core temps making it that much more impressive.

I'm going to run this clock for a few hours like always, and then.....*gulp* try for 4Ghz again to see how much it takes to get stable if at all.

Thanks slot for the info Kei, lotta good stuff in there. I had bought the Scythe fans for my ex water cooling. HW Lab radiators worked great with flow fans so they recommended me those. Since I still have them why not use them.

Amazing how a fan that flows that much less is actually more efficient.

Kei what do you think of the Corsair H50 inside the Coraair Obsidian? Yes, I am in love.

I'm thinking that the Gentle Typhoons will do EVEN BETTER than the stock V8 fan. They have a pretty serious reputation for static pressure being comparable to 38mm fans which is pretty amazing. I love that Scythe slipstream, but I've always had the feeling that there was something out there (or in here lol) better with less noise I just never bothered to research until now.

I looked at that Obsidian last night............I didn't have words for that case when I read the review last night....I still don't have words now.

That thing is an EFFIN MONSTER!!!!!!! When you get the H50 I'd say it's probably the smartest thing you can do to get some fans with high static pressure. My temps were very nice with the H50 using the Scythe and V8 in a push pull config. I'm 100% certain that they'd be ridiculous if I had used two V8 fans instead. I even had the Scythe as the push fan which was stopping me from max cooling ability anyway.

Even with an unoptimal fan setup and no lapping of any kind on the processor (did I mention how HORRIBLE the flatness was on my processor?) or waterblock (which absolutely needed it), and I STILL only got 46-48C at 1.50v to the processor.

If you lap the waterblock, the processor, and have some proper heatsink/radiator fans...I'm afraid of what that thing could do lol.

[Chicken Patty]

Yeah what amazes me the most about that case is th attention to detail. The hot swappable bay, it brings the connectors and a cover for when verything is covered up. The cable management on it is just out of this world. .

I will do some research now that thanks to you I have better insight on fans. I really can't wait. I'm ordering the case an H50 on the 29th!

 

[Kei]

The cable management is amazing in that case, but my favorite part easily was just the stealthy look and function of everything. When I got to the part about the 140mm side fan under the Corsair logo I nearly fainted! They've done a marvelous job of making the seperate cooling zones to keep airflow optimal throughout the case.

If I was looking for a full tower case this would be EASILY in the top 3 cases I'd choose between. Corsair has done a truly outstanding job with this case. It's gonna be kinda funny seeing the H50 in that case...make sure you don't lose sight of it when installing it or you may never find it in the great black expanse of space.

Kei

 

[Chicken Patty]

That's exactly what I meant by attention to detail. The fan is hidden an another one can be added in the bottom cage if you need to. I am really contemplating a custom water cooling setup. kei since you personally had one you might know. If you wanted to change the tubing on the H50, would it be possible?

 

[Kei]

Yes, it's possible to do so and I've seen some things on the net floating around about it. However...if you're meaning change the diameter or something like that I'm not so certain it would work out. People have changed the hoses for the 'pretty' stuff before, and it didn't seem to really be an issue or much work involved.

That was one of the things that I wasn't too big a fan of with the H50. The hoses are just kinda 'meh' looking, though I didn't want any super neon lighting kinda stuff...just something smooth looking I guess? They are VERY nice and sturdy though which is a plus and minus at the same time. I have no doubts that they'd hold up very well and have less than 0 kinking problems....but they also don't bend very easily which may cause some people to get pissy while installing. It wasn't a big deal for me, but still something of note I suppose.

well yay my internet provider is being a douche (im only getting 1mbps peak comapred to the 8mbps i pay for im also experiencing about 15% packet loss) so i get to sit here with no online gaming to speak man i just love it when techsuppore dosent no jack shit other then that

i attempted to get my Ram to operate at 4-4-4-12 1 T but it just couldnt get it 100% stable

 

[Chicken Patty]

@kei
yeah I might change it out for some UV reactive tubing o maybe just some black/ UV reactive tubing. I'll read up on it a bit more now when I get home.

@eyes

how much voltage did you try to get it stable?

 

[crazyeyesreaper]

well default for my sticks are 1.8 volts i tried up to 2.1volts and it wasnt enough the clocks just werent stable so i went back to 5-5-5-15 2T

 

[Kei]

Answers and more!

Good deal, from what I've seen on the net it looks pretty cool if you have a side window to view it through.

In other news I failed in pretty epic form today trying to get the 4Ghz clock (well 4.025Ghz) any form of stable with this board.

Then God himself came in the room sippin on ginger ale (Canada Dry of course lol), and told me to move over and let him have a crack at it. Well.....turns out he's pretty good with computers because he blessed me with the following result that's been running now for 37:45 min so far without so much as a hiccup.

He didn't use any ACC in the bios settings at all nor did he up any other voltages on the system. He said I was trying to do things the easy way, and I strayed from the path of the truth in doing so. As soon as he guided me back to the path of righteousness the computer opened itself up to me.

Before this point I couldn't get it to run for more than a few minutes....if it even lasted THAT long. I needed ACC just to get it to run for whatever time it did run. I couldn't pass anything more than the 8M SuperPi test though it did that pretty well.......once and never again lol.

Since God booted and setup the computer it hasn't had a hiccup in the least bit and has passed both the 16M AND the 32M SuperPi tests back to back...followed immediately by a wPrime 32M test.

He had to go help someone else see a man about a horse so I'm going it 'alone' for right now...though he mentioned something about always being right here with me. When I get up the courage (aka after 1 full hour run time) I'll attempt the 1024M wPrime test to see how lucky I am today.

So everything else is bone stock voltage?! What about the NB/CPU VID or HTT voltage. I want God to bless my computer too.
