Concern over temp spikes

[Guest]

My Ryzen 1700X at idle will sometimes follow a very odd pattern according to HWMonitor. It will hit 39 degrees Celsius, slowly go down until it reaches 30 degrees, then spike back up to 39. I am aware these temperatures are fully within the safety threshold of the processor, but I'm concerned the amount of spikes happening consistently over time may damage the processor. Thoughts?

The fan curve is probably set weirdly.

I'm willing to bet if you leave the fan at a single speed it'll even out. obviously pick a high speed.

i tried and no difference

plug the fan into a constant source of power like a molex connector, lets just check and make sure cooling has nothing at all to do with it.

after that , check and see if in task manager if the cpu usage increases with the temperature.

also check and see if the cpu is throttleing back in terms of speed when the temp goes up.

if the machine is idle , the fan is constant , and the clock speed is constant , and the temp have a repeating pattern of temperature spike , it very well could be a manufacturing defect which seems to be somewhat common lately with cpu's

the temperature and clock speeds have no correlation, so i am confused. could it just be its reading temps inaccurately?

what program are you reading temps with?

HWMonitor

each core will have it's own sensor if it's showing it correctly , is it just one core or all of them at the same time?

all at once

well last step would be to stick a physical temperatur probe on the heat sink as close as possible to the contact point with the cpu. if a totally separate piece of hardware can confirm the consistant temperature spikes , then the cpu might actually be bad. test it both with the os load and just idle in the bios

in fact check the bios temperature reading right now and see if it also shows the cpu temp going up and down with no os loaded
