For what is the reason that only the Asetek AIO cooler is recognized by the motherboard yet not a case fan?  According to the board manufacturer, MSI, this should not be the case.

I purchased a brand new 92mm PWM case fan to try as well.  What I discover is that the PUMP_FAN header on the motherboard seems to supply full voltage to whatever fan you connect to it regardless if that's a case fan or the CPU heatsink fan, which makes sense if it's powering an AIO cooler pump, it runs the pump at full speed.

 

However what I am still confused about and what no one has been able to provide me an answer with is why shorting pins 1 and 4 together on the Asetek AIO cooler pump wire harness seems to "satisfy" the motherboard.


I still have the Asetek AIO cooler pump in my possession, and plugging it into the PUMP_FAN header once again satisfies the motherboard and it immediately ceases to give me the fan error on boot.  It is only fans that produce this error when connected this PUMP_FAN header.
