Ryzen 1400 OC Weird Temp Spike in Aida64
I am not sure if this has already been discussed in another thread since i couldn't find one with a similar discussion.
I recently built a PC for my fiance with a Ryzen 1400 and MSI B350 PC Mate mobo. I overclocked the CPU to 3.8Ghz at 1.35v with a hyper 212x cooler. Under load the temps never go beyond 70-75c in Aida64. I stress tested it for 30min (just to do a quick stability test to check OC. Will do a proper test once i am happy with the results) and i noticed very weird spikes in temps. On average the the temps would equalize at around 70-75c under load, but every couple of minutes (+-5min) or so, almost periodically, the temps would spike by 10c to around 80-85c. I check whether it might be an increase in voltages due to the LLC, but the voltages never increased at all (stayed at the 1.352 mark).
So i was wondering if this is normal for ryzen since i did not experience the same spike with my 6600k oc which remained within the same temp range during the stress test. Also a 70-75c temp on a Ryzen 1400 oc is roughly where i expected it to sit with a hyper 212x and the jump in temps is strange for me.
The pc build is as follows:
Ryzen 5 1400 oced to 3.8ghz @ 1.35v
MSI B350 PC Mate motherboard
1x 8Gb DDR4 2400mhz memory
Antec 500W PSU
GTX 1060 6GB
Hyper 212x Cooler
