Doesnt sound like a bearing, just sounds like the fan is ramping up a few RPM. And regarding speed, thats what i thought it was a few week ago when it was boiling outside. However now its a abit cooler, temps are fine according to HW Monitor (CPU, system running mid 30c) so dont think its that.
Is a bad bearing more of a grinding noise?
