When I go to mointor my temps with SpeedFan what are "Core 4, 5, 6, 7". It shows they have a temp, so that always confused me. I know Core 0, 1, 2, and 3 are my core...

thread 1 and 2 = core1
thread 3 and 4 = core2
thread 5 and 6 = core3
thread 7 and 8 = core4

I think that's what it is.
If you're trying to set it to auto control.. I'd set the wanted temps for all cores at like 65, and the emergency temps at 75, for each thread. (if it's an i7)

That makes sense I guess, and I thought it might be like that where they are counting logical cores instead, but it doesn't say Thread 1 and 2....7, it says Core 1 and 2....7, so I was just making sure..

EDIT, finally found a thread on it, and yeah you were right, its becuase of Intel's multithreading.

I don't understand why the threads all have (in slight slight variation) different tempurates, but its no big deal.

The variations in temps is common.. It depends which threads the CPU is using mostly.. Could be other factors. I know, on mine, I usually see one core thats a few defrees hotter, or 2 cores sometimes. It's different from time to time.

Thanks!
