CPU Fans

[MaTTraP]

Hello to anyone reading this, I have a question that maybe someone will hopefully help me with, so I randomly noticed that my CPU Fans stopped spinning, however my CPU temps were staying in the 60's and 70's so there was no overheating happening. I have a Cooler Master Hyper 212 Evo and a Ryzen 7 1700X, I did have my CPU and RAM overclocked but decided to reset my bios back to default settings because even though I had it stable I still experienced some crashes in games. Resetting the bios fixed that but anyways here's the real kicker. I saw my fans stop spinning while I was getting into a League of Legends game, after the game was over I was about to restart my computer but then noticed my fans started spinning again o.O I don't know why or how it happened but could perhaps somebody possibly have an idea on why it did this? I'm not using the fan that came with my cooler, I'm using Cooler Masters high performance fans at 2000RPM.

For the record, that means not stable

 

If the fan doesn't spin but you're still cool, that's pretty incredible. Does the fan kick in when you stress test? Have you tried Aida64 or a more CPU intensive game?

Have you checked to see what your fan curves look like? Go into the Bios and see if at what point theyre set to spin up. On some Asus boards this can also be modified in windows. 

 

The other possibility is a bad bearing which is causing it to intermittently stick and not spin...
