Disappointing NH D14 temps?

Goose · 25 Nov 2013 at 20:14

Installed this cooler yesterday and have started playing around with OC'ing today and i'm a little bit disappointed. At idle the package is at about 36c and under load its hitting 70c on a 4.2ghz OC with vcore (offset mode) jumping between 1.320 and 1.328. Both fans are running at full speed and I have 4 Akasa Apache's as case fans (2 intake, 2 exhaust).

Am I right to be disappointed?

makesure its mounted correctly,what paste did you use?

for comparison I have my 2600k @4.5ghz with 1.344v and get 72-75c at most,using mx4 thermal paste maybe lower as I cant remember off hand

that's max stress in intel burn test

I'm pretty sure its mounted correctly, i was checking each part along the way. Im using some Gelid paste from my old Tranquillo because I couldn't find my old Arctic stuff and the cooler didn't come with any (bought 2nd hand).

id say low 70's is right for that cpu voltage,id pickup some mx4 paste though if you can,might improve things more

I switched the noctua fans for two apache fans,much quieter,temps are the same, pwm too

Your voltage seems quite high for that overclock which is why you're getting these temps. Have you turned on Speedstep etc to make sure your CPU clocks down at idle?

I have my 2500k @ 4.5 (need to put it back up to 4.7 now its winter) @ 1.30v under a D14 and im getting 63C max temps (prime tested).

Seems a bit hot, though i used fixed voltage and not offset. I've noticed offset increases your max temp (as it does need more vcore under load).

I'm actually running at a negative offset to get the voltage to 1.320 - 1.328 and according to CPUz it is clocking down at idle.

I use offset mode partly because that seems to be the most common method for Asrock boards and also because fixed mode seems very unstable when i've tried it myself.

Got my i5 2500k at 4.5Ghz using 1.35v I think, and is around high 20's to low 30's when pottering around in Windows or web browsing, and high 60's during Intel burn test using a Thermaltake Frio (still a very good cooler, but inferior to D14).

Could it be that I have a ridiculously hot chip and there's nothing I can do? If not, then summits wrong with my NH D14.

Until you remount it with good thermal paste you won't know if its faulty. To be honest if its a solid mount the only thing that could be faulty would be if the previous owner has tried to lap it and made the surface uneven.

When i get time on thursday i'll take it apart for a thermal paste autopsy and take some pics in case anyone notices anything obviously wrong.

When applying the new paste I'd advocate the pea/rice method over spreading in case you were using the spread method. I think a lot of people make the mistake of applying too much paste and not applying it correctly. The best thermal transfer you'll get is metal to metal contact between the chips IHS and the base of the CPU cooler, paste is only used to fill in any small gaps inbetween because it's much better than conducting heat than air but it's not as good as metal. Spreading a layer of paste on both surfaces and mounting them is not only likely to prevent the metal to metal contact you want but is also shown to potentially cause air pockets which you really don't want.
