Hello!
I've got my rig running i7 2600k at 4.5GHz with a 45x CPU ratio. It's running stable at 1.375V but the temps are too high. My cooler is Scythe Mugen 3 PCGH and it's quite huge so I thought it should do the job.
But when I run prime95 cores 1-3 hit 70C in one minute while core #0 maxes out at a tolerable 65C temperature. I think the cores 1-3 might get to 75C if I leave the benchmark on, but I don't want to do that until I'm sure it's safe. At idle speeds the core #0 stays at 35C while other cores get about 42C.
Why do some of the cores generate much more heat than core #0? Is my cooler good enough for my overclock or is there something wrong with the cooler installation?
Load Line Calibration = OFF
Internal PLL Overvoltage = OFF
System Power Supply = 130%
Phase Control = Extreme
All system sepcs below. Thanks in advance!
EDIT: I had accidentally installed the 2nd cooler wrong way around so the two fans were blowing in opposite directions... Fixed it and it's now about 3C cooler but still core 1-3 are 10C hotter than core #0. They seem to peak at 72C but I guess I can live with that since in daily usage the cores never run at a constant 100%. Core #0 peaks at 64C
I also checked the TIM on the cooler and decided to remove some of it since there seemed to be more than enough of it. Suggestions for lowering the temps via BIOS settings are still welcome!
