Broken Laptop Fan Tachometer, Any way to fix?


Mar 29, 2017
Not sure if the tachometer itself is broken or just something on my motherboard. But because the sensor always reads 0 RPM my GPU is thermal throttling itself at 67c. On HWInfo it says GPU Fan (ODN) is constantly at 0 RPM, but a little lower it has a different icon and says GPU Fan speed and stay at 19%. I've gotten fan tach speeds briefly right after boot before, but haven't been able to reproduce any similar activities, so is there any way to change sensor data/ any ideas on fixing it physically. I messed up the male end pretty bad but as far as I know the connection should be good enough. No Idea if there are any issues in the female end/motherboard
