Insane temperatures on Eisbaer

[Petoovee]

Here in my garage, just bought this new 280mm AIO watercooler here. Temps be sick tho, a few degrees higher than the 212 EVO I had a few hours ago. What gives?

 

Redone the paste, rather sure I ain't messin' it up twice, the reservoir+pump has a glas window in it, I see the pump workin. System claims the pump is spinning around at 2700RPM, and the loud ass fans just wont go below 1200RPM. Still I don't even dare starting a game.

 

On "In-place large FFTs" in prime95, I get reasonable temps the first two minutes, after that it shoots up to 78C.

The temps after just booting up look like this.

 

 

I do lack rubber sealings in me windows, but I doubt its 15 degrees in here.

So your 3570K at 4.6 Mhz is reaching 59 degrees?  Is this the highest temps you have seen, because this is really low.

Can you show the highest temps during the prime test?

[Petoovee]

 

59 degrees was windows booting up, I did some stress tests before the "upgrade" too, on the 212 evo, after 10min of prime95 it was at 74C, and definitely more silent, almost unnoticable

[Petoovee]

These are the temps the Eisbaer 240 gets

78C is a very reasonable temp under load.

But how come the Eisbaer 280 is equal to a 212 evo?

I'm not sure, I dont have any experience with that cooler so I cant really speak to the performance of it. Where do you have the radiator mounted in your case? how many fans do you have attached to it and which direction are they pushing or pulling?

[Petoovee]

Like so, fans are pull inside the top

 

From what I understand reservoirs should be the highest point in a waterloop, but how would that work with an AIO?

[Petoovee]

How problematic are airbubbles? Unless I can top off with liquid I'm bound to have them ain't I?

 

EDIT:

I actually really suspect it's the bubbles. I saw a huge one earlier, abouta teaspoon large in the respump, any clever way to get rid of them?

 

EDIT2:
A reservoir seems perfect for such a task, however opening the fill hole would surely spill the liquid out everywhere, not sure what the point was with having a fill port on the block?

Am I correct in assuming there is nowhere to mount it on the front of your case? If that is true, which way are those fans pulling? Are they pulling air into the case or pushing air out? Most fans have the logo facing out when they are pulling, so if I were to guess I would say you are pulling air into your case, which would be working against the natural airflow of your case. Heat rises , so you want to turn the fans so they are blowing air out of your case. The ideal config with AIO is to pull cold air over your radiator, but when top mounted this isnt really a viable option. As it is set up now, you have the hot air trying to escape the case, but not being able to due to the air you are pulling IN through the top.

They are blowing the air out, although my case is open for now

 

Been stressing it now for a while, 82C

[Petoovee]

Now it just dropped down to 62C?

If the load didn't change, it probably had an air bubble in it that just got burped out.

Maybe I should chill down a bit and let it settle in?

 

That air bubble prolly got stuck in the rad now instead, didn't it?

If the temps finally dropped you're fine and don't have anything to worry about.

 

There will always be some air in a closed loop, its supposed to settle into the end tanks of the radiator.

The load should've been the same, however I'm back at 80C

80 is still okay. especially since those artificial stress tests are generally putting much more stress on your system than you ever will.

That eisbaer 240mm review I posted a screenshot of is quite misleading. 7.2 delta C at 60W would mean my CPU should be running at below 30C on load. Somehow I believed 200$ of watercooling could accomplish that.

I don't know of any cooling solution that will accomplish that. I spent over $700 on my full loop and I get around 55C average under full load.

Is there any gain to watercooling then? A 30$ 212 evo performs better than a 200$ AIO

 

55C is 6C cooler than a 90$ NH-D15

That's not an accurate comparison, as the 55C I quoted, and the 61c you're quoting, are from two different chips. On my chip, at the overclock settings I've got, the nh-d15 gave me an average temperature of around 70 under load (I'm running 1.4v to get my 7700k to 5.1ghz)

 

I am not familiar with the AIO you are using, buy generally you are correct, you would hope to see bigger gains than you're getting going to an AIO over a hyper 212. I would say something isn't right there, as the 212 is not usually considered a high performance cooler, rather a budget one. What the problem is, I can't say.  Typically when this happens, it has something to do with either the mounting of the cooler to the CPU, or the thermal paste in between, but I know you said you checked that.

[PETRGangKing]

If you do end up returning that aio, I would recommend getting an EVGA CLC 280. Out of all the AIO I've personally tested, I got the best performance out of that one, and it's only $125.
