E8400 temperature oddness

post #1 of 4
Thread Starter 
Hi all,

I built a new computer for a friend today. This is the spec:
E8400
Gigabyte GA-X38-DS4 (F3 bios)
OCZ Platinum 4-4-4-15 DD2-800 2GB Kit
Innovision 8800GTS 512
Scythe Mugen (aka. Infinity) CPU cooler, AS5 TIM

Everything went just fine., not overclocking just yet, that will come after a week of settling down period.

Here is the odd thing though: The system reads (with coretemp and everest 1291) a 14 degree difference between core 0 and 1. This is quite unusual, as I understand. Core 0 idles at the 25-28 I'd expect, core 1 reads exactly 14 degrees higher, so 39-42. To eliminate seating and TIM issues, I reseated the heatsink twice, with tim reapplication each time, in different orientations. The result is the same each time. The TIM application method I use, and have used many times before successfully, including my signature system is a very thin spread with a razor blade.

So, what gives with this? I suspect that there is a bug in the thermal sensor on the cpu, and it just lies, especially as the 14 degrees difference never changes. Does anyone think I have any chance of getting an RMA on this cpu if I tried to? Should I just ignore this as an aberration?

Thanks for any help.

I heard that those CPU's have have faulty temperature gauges.

This is a common problem. He has a bad temp sensor.
