3 pin is DC pump, regardless the bios is not perfect, if auto doesn't work, try DC, remember to safe and reboot, just in case this is needed to take effect.

mine is a PWM pump, but it does not go below 60%, but auto allows it to go below 60%, so try whatever combination you can.]]> Tue, 21 Feb 2023 15:00:51 +0000 https://forum.asrock.com/forum_posts.asp?TID=25480&PID=103574&title=cannot-set-aio-pump-speed-below-60#103574 https://forum.asrock.com/forum_posts.asp?TID=25480&PID=103572&title=cannot-set-aio-pump-speed-below-60#103572 Author: kerberos_20

3pin doesnt have PWM, it relies on voltage, reducing pump speed reduces voltage, too low voltage and pump wont spin
pump rated voltage is 12v and rated pump speed is 4400rpm +-10%
there should be zero noise comming from pump]]> Tue, 21 Feb 2023 12:48:24 +0000 https://forum.asrock.com/forum_posts.asp?TID=25480&PID=103572&title=cannot-set-aio-pump-speed-below-60#103572 https://forum.asrock.com/forum_posts.asp?TID=25480&PID=103508&title=cannot-set-aio-pump-speed-below-60#103508 Author: ynr

Mine is a 4pin pwm, after set in bios to AUTO, it would go down below 60%, I've currently set it to 10% = 1800rpm in my case. 100% is 4200rpm, not noisy at all, but I don't want to shorten the pump life, hence idling PC is 10% = 1800rpm then 70C cpu will up pump tp 3000rpm. Try again AUTO but safe bios and reboot into bios to check.

pump speed should run at full speed all time..if it makes noise, RMA it

I recently bought an MSI Mag Coreliquid 280r which is making a very loud beeping noise. Some people suggested lowering the Pump speed through BIOS, which did not work for me. I have plugged it into the correct W-Pump header and set it to W-Pump in BIOS . I also set it to DC since it's a 3-Pin Header (also tried PWM or Auto to see if it does anything to no avail). When trying to go below 60% it just goes back up to 60%. Going above 60% works perfectly fine though. I am on a b550m Steel Legend.]]> Thu, 16 Feb 2023 04:27:58 +0000 https://forum.asrock.com/forum_posts.asp?TID=25480&PID=103431&title=cannot-set-aio-pump-speed-below-60#103431
