Built a new rig and unstable CPU Temperature/Rising Temps

PJ5ingh · Aug 19, 2015

I just got done putting together a new rig and I am getting unstable CPU Temperature.

Cooling unit - Corsair H105
CPU - i7 5820k 3.3Ghz Haswell

So far I've done the following..

With the pre-applied thermal paste from the Corsair H105 - The temperature started rising and it never ended until I shut it manually off. It got up to 89 C really fast.

I have re-applied thermal paste using Arctic Silver and then I got a stable idle at 50 C

I applied it again and then I got results of temp rising slowly from 40 C..to 62 and it kept going up but slowly.

One of the pipes of the pump feels like it's not pumping anything while the other I can feel something moving in there. Also when I press it down on the coil the temperature comes down all the way to 39 degrees.

What seems to be the problem?

and No I have not changed any settings. This is under the BIOS section and I haven't even installed the Windows yet..

Is the pump nice and snug? you pulled the platic off the plate that sits on the CPU? Pump plugged into the mobo? Fans spinning?

Should've gone with air, it's most likely ur pump .... even if u seated it wrong there will be some heat transfer.

Tradesman1 :

Sorry for late reply. Yes the fans are spinning and yes the plastic plate is off. Pump is plugged in the very first CPU fan without the adapter like it's suppose to. Read my assessment below and then let me know what I can do.

I re-did the thermal paste last time before going to bed. I figured why not give it another shot at the thermal paste. I did the coffee filter cleaning method and I made sure it was clean on the coil and the cpu before I applied thermal paste. The last session of re-applying thermal paste went decent but I still don't know whether should I stick with this or not since my other PC runs 27-32 C on idle.

The results were that it booted at 29-30 degrees within 5 minutes it went up to 37 degrees and then the next 15 minutes it got up to 42 degrees MAX. It stayed around 42-43 back n' forth Idle on the BIOS.

I also noticed something about the Pump pipes. One of those feels like it's running like it suppose to be. I can feel the vibration on one and the other one feels like its very silent. I compared this with my other PC's pump which are not the same but it has 2 pump pipes like this one does. Think maybe my cooler is defective?

Might be - also might be the mobo power source isn't enough, might try plugging into a PSU molex power plug if you have a 4 pin to molex adapter

Really? I didn't know it could be even related to the CPU? I have cable from older PC. It's like a Molex Y adapter that goes into power supply. Will that work?

Figured out my problem. I know I am a little late but I need to report this here just incase if someone comes across this problem. I Installed the wrong stand off included in H105. The stand off's were taller and water block wasn't making contact with CPU. I installed the shorter stand off's and got the right temperature what I was looking for. around 30-32 on idle. Stress testing going anywhere from 40-48 degrees

Very good, glad all is well
