Thank you for your response.
I didn't think I would need to lap it, so I just cleaned it with isoproprynol and re-applied the TIM.
I dont knwo hwo i can tell if i am reading the CPU temp or core temp, how do read the core temp?
I have downloaded three applications, the asus ai suite which says the CPU is 39C. HOWmonitor says CPU is 39C, temperature package is 23C. VCORE is between 1.1 - 1.3, i imagine this is the power reduction feature.
Core temp says CPU #0 between 23C - 30C, jumps up and down.
Running PRIME95 for five minutes, asus ai says 54C, Core temp says 34C, HWmonitor says cpu 54C and package 34C.
Maybe it is cool then and i shouldn't worry. Dont know ambient though probably between 18-20
