Consistent large R5 3600 Temperature spikes when benchmarking

[zac9500]

Hi all,

I've had no luck anywhere else figuring this out. I have a new R5 3600 installed on an MSI B450 tomahawk max, cooled by a hyper 212 black in a very well ventilated case. When benchmarking AIDA64, I get 10 degree spikes of temperature from 70-72 to 80-82 degrees at consistent timed intervals. (SEE PICTURE)

I have OC'd the CPU all-core to 4.2ghz @1.3v in the bios
I have OC'd the DDR4 3600mhz CL18 kit to 3800mhz CL18 @1.4v

I cannot for the life of me work out why it's spiking at these intervals and no one seems to be having this same problem. Is it voltage related?

Please help!

Have you actually checked the voltage when benchmarking? Also have you tried any other benchmarks like OCCT?

Hi! Whilst benchmarking AIDA64 stress test, the voltage is jumping between 1.2580 and 1.2820, but it doesn't seem to be in line with the temperature spikes. This is odd to me, as I manually set the CPU Core voltage to 1.3 in the bios? I thought it would lock to that but obviously not.
