hey guys my brother just built a new pc not that long ago, everything was working fine and then today it suddenly decides to boot up with cpu fan error. We checked to see if his stock fan (ryzen stock cooler) on his asus tuf b350m plus motherboard was ok and it was in the right header. The fan still spins fine but when ever we go into the bios we notice that in cpu fan speed it says 'N/A'. The other fans show the rpm and no problems. Again the pc was fine for 2 weeks and now this happens out of the blue. any help? We also tried setting motherboard to default settings and still giving us the issue, for now we have ignore monitoring rpm, will this affect how it responds to increases and decreases in temp or is it simply that we cannot see the rpm (not a big deal unless the fan completely stops spinning)
