KrsCph Posted February 14, 2019 Share Posted February 14, 2019 Building af new rig (based on Corsair 500D RGB and Gigabyte Aorus Z390 Master). According to the instructions I should connect the H100i RGB Platinium to the CPU_fan header. However, the H100i is made for a 3-pin fan connector and all fan headers on the board are 4-pins. What to do? I should mention that I would like to control alle fan headers by the Corsair Commander Pro which is able to control six fan headers. But as I can tell, I still needs to connect the pump on the H100i to the CPU_fan header. Regards KRS Link to comment Share on other sites More sharing options...
DevBiker Posted February 14, 2019 Share Posted February 14, 2019 The 3-pin connector will connect just fine to a a 4-pin header. Connecting the pump provides a tach signal to the CPU_FAN header, which prevents a CPU_FAN warning. It's optional but desirable - you'll get an error in the event of total pump failure.
