H100i + 3770k water temp vs cpu temp delta

post #1 of 15
Thread Starter 
I've recently upped the clocks on my i7 and I'm not liking the load cpu temps, even though the water temp barely budges.

Tested running Prime95 26.6 Small FFT:

Immediately after starting test


After 15-20mins


Immediately after stopping test


I am concerned that the cooler isn't making good contact, I have mounted using Arctic Silver following the instructions on their site. Is this delta normal?

Going to a more up to date TIM might net you a couple of degrees. But, really the weak links are the Haswell TIM under the heatspreader and the Asetek CPU block. Your results are pretty much what is to be expected with the components you have.

Thats disappointing but thanks for the quick reply. Whats the best way to drop those load temps? Anything on air, or straight to custom loop?

Hard to say without knowing the specifics of the system. I can see the MB, CPU and GPU in your results, but what case are you using and what is the fan setup?

Just a thought as well as what Ciarlatano said above, are you using the stock fans on the H100, and what are your room tempreatures?

Looks like your running 1.144 Vcore at 4.4?

For reference I'm putting 1.32 volts at full load through my 3570k non-delidded to get 100% stable at 4.4 (very bad chip). I get under 90c in Prime with a 30c summer ambient, and under 80 when its around 20 like now with a Cryorig R1 Ultimate.

A correctly functioning and well ventilated case with a H100i should easily be able to handle 1.144 volts 4.4 on a 3770k.. You might have a pump problem.

I am running an original NZXT Phantom Full Case with
140 front,
2x120 side,
120 rear
h100 w/stock fans top

front and side intake, rear and top exhaust. Temps inside the case seem fine, (the h100 stays cool when cpu is loaded and the gpus don't go over 70 in-game and mobo temps seem reasonable) I just want something that is going to drop the delta between the cpu temp and heatsink temp..

Prime candidate for delidding there.

Going by some of the not delidded temps, voltages and coolers used in the results here, it could be one of the worst TIM jobs under the lid yet, or theres a problem with the cooler IMO. Unless ambient temps are way up there in the mid thirties and the GPU's are unaffected.

If it were a pump problem it would be shown with high liquid temps, and that is not happening.

As much as I hate the "let's just throw out today's buzzword" suggestions, this might be an answer, if in fact the issue is the IHS TIM......but it is far, far (not to mention really, really far) more likely that the mount or TIM application is bad. "Butcher your CPU with the risk of killing it" is not something to get tossed around so lightly.

Your airflow looks like it is set up well. First thing I would suggest is getting a new tube of current TIM (GC Extreme, Noctua NT-H1, MX-4) and try a reseat. You could simply have a bad seating or bad TIM application. Keep it simple with one of those three TIMs - they are easy to apply and spread well by themselves. Don't fall for the whole "but XYZ is 2 degrees cooler......if you happen to get it to spread correctly". You already have an issue, no sense in simply changing it to a new issue.

If all else fails, with the airflow you have, a top tier air cooler will outperform the H100i, and will be significantly quieter in doing so. But, no sense in dropping $80 on a new cooler if you can solve your issue with a $7 tube of TIM. Unless you are looking to go quieter in the first place.
