Re: Q9650 Temperature problem

NM

It certainly does seem odd that one core's result is so different. After some research, this could be HSF related, but you pretty much ruled that out...

Yeah, one core being MUCH higher than the others I'd think HSF or at least the contact with the HSF...

It seems to be normal for these core 2 quads (both the 65 and 45 nm parts) to have 2 cores warmer than the others.

Here's my Q9550 @ 3.85 GHz idle:

floyd@pflog:~% sysctl dev.cpu.0.temperature dev.cpu.1.temperature dev.cpu.2.temperature dev.cpu.3.temperature
dev.cpu.0.temperature: 28
dev.cpu.1.temperature: 28
dev.cpu.2.temperature: 24
dev.cpu.3.temperature: 24
Notice the 4 C difference between cores 0/1 and 2/3, and the difference is greater when under load. As a matter of fact, one core in my case IS appreciably hotter than the others by 11 C (versus the OP's 15 C).

root@pflog:~# sysctl dev.cpu.0.temperature dev.cpu.1.temperature dev.cpu.2.temperature dev.cpu.3.temperature
dev.cpu.0.temperature: 47
dev.cpu.1.temperature: 38
dev.cpu.2.temperature: 38
dev.cpu.3.temperature: 36
