In the last couple weeks I have had a CPU fan error on two separate occasions. After rebooting a couple times the error disappears and my temps are the same as always. I have seen some people report problems with Asus z87 mobos and cpu fan error, but they all say that their fan still spins. My pump is connected to the CPU fan header though, and if I go to the monitor temperatures tab, I can see the CPU temp steadily rising so I know the pump is not actually on. Is this a problem with the pump or is it just a fault with the mobo? The liquid cooler is a Cooler Master Glacer 240L, less than a month old.
