Hey...I have a ASUS P5N-SLI mobo and everything worked fine and then all of a sudden i turn it off and back on (properly) and it beeps saying the cpu fan is not working...I plugged it in a few different fan locations that were currently working and it still failed to power on even after being turned off and back on....I checked the temperature and the CPU was htting 70 so i turned it off and have left it off as ive seen that temp can be very dangerous...Does anyone have any suggestions for fixing? It is a watercooled fan by coolermaster..I can give more details if needed...Thanks for reading and hopefully someone can help
