How do I connect my AIO to my motherboard?
Moreover, can I plug case fan into AIO pump?
See More: Will a case fan work plugged into the AIO_PUMP connector? The AIO-pump is designed for a water-cooling system , most likely together with the EXT-FAN (sensors). The CHASIS-FAN's should be sufficient. You can also use fans running at 12V running at a continuous (high) speed.
In this regard, should I run my AIO pump at 100?
Pumps should run at full tilt, for maximum liquid flow. That is why most AIO coolers (minus digitally controlled models such as corsairs I series) have their pumps attach to a 3 pin fan header, to run at 100%.
You are probably wondering if AIO coolers need maintaining, the answer is yes. Not like how Custom water loops need maintaining, they require you to maintain everything. With customer water loops, you only need to maintain the fans and the radiator, make sure they're dust-free.
