Intel Core i5 3570K @ 4.8 GHz, abnormal temperatures on one of the cores.

post #1 of 6
Thread Starter 
Here are the temperatures that I'm reading:

Core 0: 23°C
Core 1: 37°C
Core 2: 23°C
Core 3: 31°C

I've already tried remounting heat sink and replacing the thermal paste on my CPU, using the Thermal-take Frio CPU Cooler.

Would I be able to RMA this cpu because of this? (The second core can vary up to 15°C of temperature at idle)

you dont need to RMA. this is completly normal. somehow one of the cores is always like this. i have the same on my 3570k with 4.6 ghz @ 1.32v.

during prime testing core 2 maxxed at 85C and others were in 70s. maybe its becouse bad TIM under the IHS, but it only my guess...

you dont need to worry though

Not abnormal at all. I'm sitting at 42 / 36 / 29 / 37 just browsing.

Some programs will run on a single thread and cause a higher load on a specific core, while the others are sitting idle. Unless you have a single core hitting 105c and throttling, what your seeing is completely normal.

Do you have the same 15c difference when at load,and what method did you use to apply thermal paste....I have had 1 core higher than the others but never 2....Did you shut down all back ground programs....?

It generally helps if you delid.
It's common that the temperatures across the cores are different but improve after a delid.

My 3770K's coolest core is 20C cooler than the other cores under P95, so it's normal.

My CPU is delidded and under custom water loop.
