Uneven Core Heating

Go to solution Solved by Deli,

Hi guys, this is my first time in this community and I am really liking it here. Anyway, I have an i7 879 and I have overclocked it to 3.75Ghz. I am using an H80i for cooling and Arctic Silver 5. But using prime95 and GPU Temp, in the tortute test, Core 0 remains at nearly 95 while core 3-4 are at 86-88. I would like your suggestions as to why this could be happening.

It's quite common. My i7 4790K's core nr. 3 is 7-8C cooler than the other three cores. My old i5 2500K has a similar "problem". I don't think it's much of a concern.

Hello and welcome to the forums. Please follow your topic so you can recieve notifications in real time...

 

I think it might be a faulty sensor or uneven loading... What sftware are you using to monitor your temps?

GPU Temp

And sorry, the processor is the i7 870

 

Try using HWMonitor or Aida64 to measure the temperatures and try measuring again...

dont use prime 95 unless you want to break stuff.  Also, uneven temps between cores is completely normal. There will always be a variation.

Sorry a bit off topic, but I have always used prime95 aswell for stress testing my OCs. If prime95 is bad, what's a good alternative for OC stability testing?
