What are the cons of using a 560mm radiator?

[Lei]

Hi there,
I'm trying to decide between 280 45mm rad or....

Turns out thickness only gains a few watts while adding 40% more weight.
I looked at the excel sheets here for alphacool
Radiator Size Estimator | Overclock.net

a 240 XT45 weights only 50 grams less than a 420 ST30, while the 420 dissipation heads a few watts over twice as much.

240 45mm weights 1075 grams
420 standard weights 1125 grams

Data for 560 is not available, but since 140 st dissipates 68 watts and 280 is double that and 420 is triple, then 560 standard 30mm must be 272w@1000rpm, 328@1250, 361@1400, 439@1800 and 510@2200 rpm


We put the rad outside the case, so case size doesn't matter. Any other cons? Is 560 too long to suffocate the pump, empty water channels? air bubbles? It certainly is a lot cheaper (40%) and 220 grams lighter than two 280 standards.

All reviews on Amazon were positive for all thicknesses of 560. One said he doesn't need a reservoir anymore.
As I travel, I need to stay within limits of airline baggage rules, So I want best weight to heat dissipation ratio.


Actually my case looks similar to this Amazon customer's pc, he purchased a 560 with 60mm thickness, I'm surprised to see he mounted this skyscraper vertically:

Here if you don't restrict the case size, EK recommends a quad CoolStream XE 480 radiator in horizontal position.

Custom Cooling Configurator | Custom Loop Configurator

If EK advices on 480, I don't think 560 is much longer. Besides EK suggestion is 60mm thick triple stack! I think coolant has a much more free transition in Alphacool 560 ST30

Notice EK doesn't suggest the 560, because the thickest 560 they have is 40mm - Cooling power 835 watt - 2.06kg 60x14x40 FPI 18
EK-CoolStream CE 560 (Quad) – EK Webshop (ekwb.com)

Their 480 is thicker and has cooling power of 957 watts - 2.1kg 52x13x60 FPI 18
EK-CoolStream XE 480 (Quad) – EK Webshop (ekwb.com)

let's estimate Alphacool thinnest longest rad : EK thinnest longest has cooling power of 710 watts - 1.93kg 60x14x28 FPI 18
EK-CoolStream SE 560 – EK Webshop (ekwb.com)


So ACool thinnest longest (lightest) compared to EK's counterpart is 440 grams lighter (version 2 is 755 gram lighter), 23mm shorter
AAAAAND acool's chambers are copper while EK is brass. so cooling power of acool must be >710 watts.

with only 1.5kg - that's a lot lighter than 240+360 - one less fan too

Your positive you want to take a rad on a plane? A gigantic 560? With an open style case? Unless you have some kind of customized suitcase it sounds like a disaster waiting to happen

Oook, you'll need to have a rad grill and fan grills to protect your rad fins and fan blades from getting crushed or broken (plastic would be lightest but fragile). QDCs will be a must. All added weight, not including coolant.
You could go without a res with the st30. Just keep in mind it would have to be mounted like the one in the Amazon pic so you can fill and bleed it with a spare piece of tubing. It will be a time consuming pita. Much more likely to accidentally run your pump dry with no res attached to it. I wouldn't go that route myself. Even a small res will make filling and bleeding much easier. If your using a real ddc or d5 pump you wont have any problems with head pressure or flow. If your using a knock off, who knows.
Copper vs brass end tanks makes little to no difference in temps. The heat is transferred via the tubes to the fins.

My best advice would be to do your head to head with the hardwarelabs gts 560.

Its the best thin rad you can get. IF you can get one go with that. Check out some reviews. You'll see what i mean.
Best of luck!

Well it fits, I'll get a bigger luggage anyway. Hope it doesn't bend. Feels lighter than I expected. I have two phanteks f140xp, may be I won't add any more fans

 

[mtcn77]

Is that intercooler for a turbo engine?

 

[Lei]

Sorry about nemesis 560gts, i could not find it in any local online store. Besides alphacool 560 was priced 2$ higher than 420 in the same shops.
But thanks for the advice, looking at reviews about other companies long rads is a nice idea.

 

[mtcn77]

Has anybody seen any temperature gradient vs specific heat load radiator tests? It would be interesting to know how much a radiator affects cooling and noise specifically.

A 560 rad for cpu alone? I'm using a 280/45 and a 240 for cpu and 980ti and temps are great

 

[xtreemchaos]

A 480 is morethan enough for a cpu but if you like over kill why not. i run a 3900x + gpu on a thin 480 and its cool no matter what i chuck at it same case too.

You mean the pic from Amazon customer? May be he hasn't bought gpu block yet waiting for backplate active cooler.

Did you put all 4 fans on it? I hope I can cool with 2 fans.
My system same as yours, gpu 30 watts less 1070

 

[xtreemchaos]

ive 8 fans push pull but thay run a 500 to 600 rpm.

Initially, I was going to suggest the BlackIce Nemesis GTR 560, but it appears weight is the main consideration; at 3.432 Kg that is considerably heavier than others.

It does have 2800W of cooling capacity, though.

Hi,
Computers use besides travel the cpu/... is missing other than using a 1070 gpu with no block yet which not sure why it would need to be water cooled
So seems an interesting question and why you need watercooling at all.

Frankly from what you have stated there's no need for more than 280x45.. although I would stay away from ek CE series
If your stuck with ek products PE or XE series are the only ones worth looking at.

Otherwise I'd say mora3 360/ 420 seeing it has stands, fan guards... available but I have to assume cloths are also going into the case lol

Hello,
that first picture is not my pc. It's a customer from Amazon who purchased a 60mm rad with a drain hole. Mine is standard 30 without drain hole.
I will upgrade my gpu when all miners get terminal cancer. My 1070 does have a block, I got a 1080Ti block and sanded it.

I need watercooling because I won't live forever and can't aircool during my ephemeral lifespan.
280x45 is 77 grams lighter than 560x30 but less future proof
I don't have any EK product. I don't dye my coolant, dye my hair green and blue though never red

 

[ThrashZone]

Hi,
lol yeah I got that was not your computer
I asked what is the rest seeing you've only stated one a 1070.

What is radiator future proof in a ephemeral lifespan lol

If he wants to run a 560 hes going to run a 560 no matter how much people bitch and moan. Let the man build his loop. I want to see how hes going to travel with it already!

And Thrash the CE rads are solid. The PE series, not so much. Check out VSGs reviews at Thermalbench.

I'm using a CE 280/45, can't see any problem with it.

You should look on the internet for all the disasters that happen with systems being shipped for shows. These systems are typically crated in wood, and they still get wrecked. Putting a PC inside of checked luggage is asking for disaster IMHO.

I tried to warn him but he seems determined to try it. If by some miracle customs doesn't tear it to pieces thinking its a bomb. The baggage handlers will most assuredly do it in.
If i were a betting man, my money would be on the house!

Today I bought a milk carton that was compressed during transit. Makes me think of this somehow...

90 minutes playing need for speed. No fans attached, weather 24° room is not AC balcony open, coolant 28, hdd 28

After gameplay : weather 23, hdd 43, coolant 41.7
Next idle for one hour:

Now coolant 39.4, hdd 38, weather 23


Another day: Two fans attached @1000rpm
weather 27, hdd 26, coolant 29.3 (room colder than outside, because of sunlight - weather does not mean ambient)

After gameplay: weather 27, hdd 42, coolant 34

Next idle for one hour:

Now coolant 31.4, hdd 38, weather 27


Sum up:
without rad 10° up per hour
with rad 10° up per 1.5 hour
with fans 5° up per 1.5 hour

And all what you are cooling is a 1070?

 

[Lei]

3900x and 1070. Will upgrade gpu later

At this point it's much cheaper to go to scrapyard and buy an actual car rad instead of this. Use some fish tank pump, antifreeze, some cheapo block from eBay and have a powerful and cheap cooling solution.

It is not common knowledge, but they leak. Hence bad idea.

They are car rads, they absolutely shouldn't leak if they aren't broken. And I'm sure that since they are for cars, they are much more robust than rads for computers.
