This always happens after driver 23.2.1 the GPU clock spikes to 1300mhz every 60 seconds while idling or just using web browser.
Additionally after PC is on for around 8 hours GPU clock speed won't idle and will jump around in addition to the spikes every 60 seconds, rebooting fixes this though.
I'm using driver 23.2.2 and it has both of these bugs. 22.5.2 doesn't do this
