CPU temp hits 80C then cools back to 55/60 [memtest]
I was running memtest on an LGA2011 system that seemed to have memory issues.
I noticed that when memtest starts, the core temperature is up to 80 Celsius. Then it drifts back to 60 (with full 8 DIMMs). Testing only 2 DIMMs at a time it goes lower to 55 Celsius. This is single-threaded test. So what is memtest reporting? Just the active core, rather than average of the die? This PC has a water cooling system. There is no model number on it, so I can't determine what the thermal capacity of this cooler is. The radiator fans seem to be going at fixed speed. CPU is i7-3820. The RAM speed is 1600 MHz with CAS 10. No overclocking is set in BIOS. |

It's hard to say what core it is. I noticed this happens when the PC started cold, i.e. after it was off for at least 3 hours. So I speculate that the no-name Alibaba cooler has a sticky pump, which only breaks free after the CPU got hot and cooked it? |
