Earlier today my computer shut off due to a processor overheat which made no sense because I'm using a liquid cooler. The BIOS wouldn't show fan speed for any fans, but did register the fans. My cpu cooler's fans are running, but the tubes get increasingly hotter the closer you get to the cpu. It may be a pump error, but that doesn't explain the chassis fan speeds not registering. The fans are all plugged in to the pwm splitter that came with the cooler.
