Weird CPU temps

Carcin0Genic · 17th July 2012, 3:10 PM

So ive just finshed building my first pc, got it running nice and smoothly then decided to check my temps with SpeedFan. To cut a long story shot, WTF?
GPU - 28
HDD 1&2 - 27C
Then there are 5 other which are called Temp then a number with 2 double ups.
But what im finding strange
CPU Core 0 - 6C
Core 1 - 9C
Core 2 - 10C
Core 3 - 9C
Im using a 3570K on a z77x-d3h with a Cooelrmaster hyper tx3 evo.
Can someone explain this to me please?
Ambient temp is about 20C

Incorrect readings, try real temp

Thanks. Seems much more accurate. Sitting on about 60c on prime95 for an hour. Is it normal for core 0 to be 8 to 12 degrees cooler than the other 3 cores when under load?

Shouldn't matter, If your worried you could try reseating the cooler

I have the same issue and after googling around I've come to the conclusion that it is pretty common for Ivy Bridge to have a large temperature difference for one core.

Usually the middle two cores are the hottest, with cores 1 and 4 somewhat cooler. 12 degrees is a pretty big gap though, you can reseat the cooler if you like but don't count on the temps getting much smaller.

Yeah, this happens on most processors if I am correct. My x5504 x5560 and 930 did this.

Gaps widened to about 8 degrees on full load.
