[SOLVED] Odd CPU Temperatures & Voltages Using SETI@Home Via BOINC 6700K Hyper 212

[jerubedo]

Hi everyone,

I'm having an interesting situation to say the least. My CPU (i7 6700K @ stock cooled with a Hyper 212) is pretty decent on temperatures overall. Using Prime95 without AVX, it caps at 72C and the core voltage according to CPU-Z is 1.248 V. With Prime95 WITH AVX it goes no higher than 85C (not terrible for AVX on air) and the core voltage is 1.296. Now, that should be the most punishing test and it should beat out any real-world scenarios, right? Well here's where it gets hairy. I'm running SETI@Home via BOINC. It pegs the CPU at 100%, and the temps on my hottest core reach 100C and the other 3 go up to 92C. They don't stay there, though. They drop back down to 85ish and then jump back up to 92/100 and this happens every few seconds (probably throttling). The GPU is not being used at all during this. The voltage reported is 1.368. So, I guess my question is: what the hell?

This system's specs:

i7 6700K
Hyper 212 Cooler with Arctic 5 Silver (already burned-in)
16 GB DDR4 @2400MHz CL 15 (X.M.P. enabled)
ASROCK Z270 Killer SLI/AC
AData 128GB M.2 SSD
EVGA 500W W1 PSU
GTX 1050 Ti
Cooler Master HAF X Mid Tower
2x 120mm front fans as intake
1x 120mm rear fan as exhaust
1x 120mm top fan as exhaust

No idea of seti at home's workload but it definitely could be more avx and some other instructions that run hot heavy. Though you could just manually set voltage to whatever it uses in prime and probably get same yemps as prime
