Ryzen 5 2400G Instable Temperatures in Idle

Discussion created by kokan on Jun 9, 2018

Hi there,


Recently assembled a new PC with the following specs:

- Ryzen 5 2400G

- Gigabyte AX370 Gaming 3   

- 2x4 DDR 4 Corsair LPX

- Samsung EVO 860 250Gb SSD

- W10 64bits


Right after it booted and windows was installed I noticed that the CPU fan would randomly kick into high gear every now and then, even if the PC was idling.


I installed all the drivers I could find both from AMD and Gigabyte + updated the BIOS to the latest version. The issue remained.

Monitoring the temperatures I noticed that they would have peaks going quickly from 30ºC to 50ºC without doing much. Decided to run a Prime test and the CPU goes to 80ºC and seems to stay there or around, I didn't dare doing the test for much longer.


I proceeded to replace the thermal paste, thinking that the first try wasn't good enough but the I still have the exact same issue.


Anyone has any ideia of what it could be?
