Arctic Liquid Freezer II - 360 rev 4 slow fan speed

[bitbum]

Hello All, I am working with ALF II 360 rev. 4 mounted to a i9 10900KF. Motherboard is Asus ROG Strix Z590-E Gaming WIFI.

ALF 4 pin is connected to CPU_FAN header. In UEFI the CPU Fan Q-Fan Control is set the PWM Mode, and Profile set to Full Speed.

HWiNFO and AI Suite report a max CPU fan speed of 1,666. Even when CPU cores reach 90C plus, rad fans max at 1,666.

ALF rad fans spec at 200 - 1800.

I would like to see fans spin at 1800.

Any suggestions?

most fans have a +/- 10% disclaimer... put better fans on it, theyre only 56cfm, and make sure the pump is at max. also check that your mobo isnt feeding the cpu too much voltage. and finally, dont expect it to get to too much better, they are hot chips.

This is normal.
My 140mm Noctua industrial 3000 RPM's spin at 2903 RPM max, and my 120mm industrials spin at 2566 RPM max.
