Ryzen 7 3700x fan 0 RPM At High Temperatures
So, this is my first time with a Ryzen CPU and I'm having an issue with it's cooling system.
I'm getting around 70-90ºC with my PC idle (just using the browser) and the CPU fan isn't working 100% of the time. It stays on 0 rpm for like 30-35 seconds then goes to a burst of 2900 rpm for around 3-5 seconds, and back to this loop.
I don't know much about processors and cooling but it seems pretty stupid to have it's fan on 0 rpm while it's over 70ºC, no?
I've tried a few different settings for the fan curve on the BIOS but none had any effects. I also used the CPU-Z Stress CPU test, which made it go up to 95ºC, but still. The fan always behave like I mentioned earlier.
I'm not sure if I should address this to AMD or MSI (I'm using a MSI X570-A Pro).
Is this normal? Should I get a new cooler? Or maybe return the processor?

PS.: It's a fresh processor. I've been using it a little more than a month.
