If you don't have another controllable fan header (many boards don't) then you may have to get an after market fan controller so you can keep radiator and chassis fans at reasonable levels. You could put the pump on an uncontrollable header that reports RPM but the BIOS probably won't monitor that header and refuse to start if the pump fails. Fans on an AIO are usually noisy at 100% so you will want them on a profile. So if monitoring the pump is important then use the CPU fan header for the pump but keep it at 100% and put the radiator fans on another header that's controllable. Most modern BIOS will refuse to turn on if they don't detect an operable fan on the CPU header. The only bad thing about that approach is it doesn't monitor pump RPM which is good to use for setting an alarm should it stop, assuming your BIOS has that feature. If you've no other controllable headers this leaves the CPU fan header free which should then be used to control the radiator fans. Using an appropriate adapter you could connect it directly to one of the unused drive connections directly from the power supply. This is because it is (or should be) so quiet it doesn't matter and it assures instant cooling when the processor starts working hard. But a pump on an AIO should run at 100%, 12V, full speed anyways. Like Jeocho says, you can plug it onto a 4 pin PWM header (just observe the key-way) and it will still work, usually at 100%/full speed if it's set to PWM mode. First thing to know is most pumps are DC controlled anyway, not PWM, hence the three pin connector. But which 4-pin header do I plug it into? I've already got the fans that are mounted onto my 240 radiator for my AIO plugged into the 4-pin CPU_FAN1 header at the top of the motherboard near the ram slots (Reference to where everything on the motherboard is here: ) so at this stage what would I do?
