Temperature troubleshooting and optimizing - What is my next step? - Page 2

I also would think that it is a flow issue with the loop.

http://www.overclock.net/t/1573189/serial-vs-parallel-9-6lpm

there are lots of ways to fix a system with low flow rates, this is what I did.

I don't think creating a parallel setup will do much for such a simple loop that just has a gpu temp problem. He stated he only runs his d5 on half speed anyways.



one other thing, is that gpu block new or used? How long have you had it? Might be due for a cleaning.

already done with that loop, I am building a better loop now for that hardware, but I am using that design on my other two water loop builds and they are a single GPU and CPU being cooled.

this is my current project.

Your block either has poor contact with the gpu , there is a flow issue, or there is air in the block. I'm thinking one of the latter two since you said you've reseated the block a few times.

Im pretty dumbfounded actually, there is nothing that's obviously a bottleneck of some sort.

Im going to try to turn the top fans around just to see what happens. But I doubt it, since others with the same case does not have the same problem.

The waterblock is new, just a tad over 6 months old. Its a clear block, and I can't see any air trapped in it.

I agree that the top rad should be intake, your trying to cool hot water with hot air. You also can't compare apples to apples with other similiar setups in the same case because the hardware and probably OCs aren't apples and apples. Unless you know someone with the exact same identical components as yours and you test stock clocks.

I might have the most similar setup to yours, even including loop order. I have a 4930K @ 4.5GHz/1.35V, and a 980 Ti with a heavy overclock. My setup used to consist of a XT45 420 on top + UT60 360 at bottom both in push only, and with both rads exhausting out the case. With fans around 750-1000 rpm, the GPU would be anywhere from 44-48C under load depending on ambient, and the CPU was 55-60C. So I'd say your CPU temps looks ok assuming similar Vcore and what you mean by "full load" exactly, but yeah your 980 Ti is definitely running a lot hotter than it should be.

I know, but I can get within the ballpark via power consumption and pretty similar components, as the poster below you.

Interesting, thanks for the info.

My next step is to invert the top fans, and putting an exhaust at the rear aswell. I will do this ASAP.

Full load is as hot as i can make it, AIDA stresstest etc. 4.5Ghz at 1.25V though.
post #18 of 40
Ah ok in that case your CPU temp is definitely fine. I don't remember the exact numbers but with only a 420+360 in push my 4930K definitely went past 70C when stress testing.

As for your GPU, might be worth reseating the block and making sure you're getting adequate contact if nothing else improves the temps.

Alright, I have now tested this by putting the top fans as intakes plus an extra fan as an exhaust at the rear.
And that actually made it worse, around 4C higher temperatures.

As I suspected, this was not the issue here.

The problem is, I have reseated the GPU-block several times, and I get consistent results.
Finding the bottleneck is really, really hard for some reason.

a few pic of the water loop can go a long way to helping us help you. biggrin.gif

a camera pic, or anything will help.
if the looks of the water loop are this issue, I have some of the worst looking loops. thumb.gif
