	Dear BrickColdsteel, Thank you for choosing ASRock. Regarding your case, we would like to know which fan connector you?�re using and the fan are 3-pin or 4-pin. Also, because you are using AIO water pump, water pump should connect to The CPU Optional/Water Pump Fan header, and set to water pump under BIOS. Thank you! Yours truly, ASRock TSD

	I have this same problem but was able to circumvent the issue by setting a custom fan profile

	Dear support, Is it true that only 2 of 5 4-pin fan connectors support PWM on z370 Extreme 4 ? The rest of 4 pin connectors work as regular 3 pin connectors? With kind regards.
