I've got an ASUS P8Z77-Deluxe (beta UEFI 1050) and a 3770k that I just put together. I've noticed 1 weird thing in AIDA at this point...
Looking at the sensors listed in AIDA for the CPU, it has fields for CPU, CPU Package, CPU IA Cores, CPU GT Cores, and each of the individual cores. Now, ignore the IA and GT because they usually say the same as the package.
So, what's the difference between the CPU and CPU Package temp? Because at idle they all read the same-ish, except the CPU will be a few degrees lower. But when I'm stressing out the CPU, the cores and package temps will be like around 60 degrees, but the CPU temp will be around 40. Actually, testing it in a hotter room now, the CPU is still running about 20 degrees lower than the package and core temps.
Now, I'm not sure if this is an issue or not or if the CPU likes to fib. Using ASUS' own SW monitor, their CPU temp listing seems to be the same as the "CPU" temp in AIDA. What's the difference between "CPU" and "CPU Package"? It doesn't feel comfortable if we're getting CPU readings that are 20 degrees lower under stress than what the cores are really at.
