Rad fans to mobo headers or AIO fan connector?

DigitalPixel · December 25, 2018

I have the Ryuo 240 and in the BIOS I can't view the RPMs or change the speeds of the rad fans because they're connected to the Y connector from the Ryuo pump. So I connected them directly to the RAD1A_FAN and RAD1B_FAN headers on the motherboard. Now I can control the curve and see the RPMs in the BIOS. So is this something that is recommended or should I connect them back to the Y connector?

I don't know if the fans are dependent on liquid temp in this cooler or go by CPU temp.

If I were to leave them connected to the Y connectors my guess is the Ryuo would control the speeds via AI suite. Is that correct? I don't have my OS installed yet so I can't test this out. What takes priority BIOS or software monitoring?

so long as you can tie the fan speeds to the liquid temp (NOT THE CPU TEMP), it doesn't matter where they are connected.

Thats what I would like to find out. Can the motherboard (Maximus XI Extreme) read the liquid temps from this AIO if the fans are connected to RAD1A_FAN and RAD1B_FAN headers? The Ryuo is connected to the CPU_FAN. From my understanding this only controls the speed of the pump. I can hear the pump speed increase if I change the CPU fan curve in the BIOS.

well that's what the USB cable is for... so the software knows what the liquid temp is. so it can issue speed control commands to the fans. from the pump connectors.

i mean, i donno why you would use the motherboard headers in this instance.
