Question Whooling noice from Liquid Freezer II 420

[bubblebeebg]

Hello guys,
10 days ago i decide to update my bios (motherboard MSI Pro Z790-a) but something happened and black screen appear for a hour and decide to restart it. There was some errors and asked me to enter new PC name and password. My fans were all spinning at max rpm`s. A friend of mine updated the bios and made windows preinstal but my PC is not the same.
I have AIO for my CPU Liquid Freezer II 420, since the problems with the bios it started to make whooling sound and it`s very very annoying. I don`t know what is the connection but it`s terrible. Any suggestions what to do? Can i reset the bios and starts all over again or? ALl my fans and AIO are at auto position (as before this happened). Everything is normal, but something happened with this AIO.
Could you help me?

Nothing can happen to cooler because of BIOS update but new BIOS version may have different defaults. Try changing speed curve for fans for CPU_FAN header, (I hope that's where they are connected to). Arctic fans can have annoying sound at some RPM

Have you checked the speed of the AIO pump motor in addition to the speed of the radiator fans? It may be possible to adjust the pump speed as well as the fan speeds in the BIOS.

Well, i can adjust the speed of the fans, but what would happen if the temperatures exceed? Will the fans start spin faster? It`s very strange that before this problem everything was perfect, even at higher rpm`s there wasn`t any whooling sound. But now...

If your BIOS allows, you can try changing the fan profiles (switch off Auto and adjust manually) to reduce noise, ten monitor the temperatures. If things get to hot, adjust the fan profile to make the fan spin faster.

Pump doesn't report speed nor it is adjustable on those models.
