So my pc has run out of warranty a while ago and the stock AIO fan started rattling so it had to be changed. Since the pc has run out of warranty the only option was to use an aftermarket radiator fan. After installation i started to get the 90b fan error on boot. Any ways to fix this? Temps are fine and the system is clean, it only seems that the motherboard does not like the fan.

@Hyperprofessor , welcome to the Community.

 

I have seen this problem in the past.  Here is a guide to help you solve the problem.  If there is another connector for the fan on the motherboard you may want to swap to see if that solves your problem.
