| 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
