I am confused about temp readings in speed fan and HWMonitor. Both programs report the "cpu temp" 27-30c at Idle and 45-48c at Load, but each core temp is reported as 40-42c Idle and 55-57c Load. Which temperature should I worry about?
Not to worry. Some variance is normal. And energy saving programs used by Intel and Amd will cause some fluctuation at idle. I have some boards that cause changes in coretemp right before my eyes while viewing the program. With other boards, the temps stay uniform while checking. If you have your heatsink installed properly, stop worrying.
