AIO Pump RPM issues

[ThreePeenSoup]

I have it installed on an ASUS maximus x formula and in the bios the RPM is reading ~1800 which is half of the rated RPMS for this AIO (riing floe 240mm) which is probably why I've been having heat issues for a year.  I just can't seem to get it to run on full power.  I set the q-fan to full that didn't work, i read you have to disable q fan completely and set the monitor to ignore and that didnt work.  I tried both PWM and DC modes with full time %100 curves and that didn't work.  I'm stumped and i know this is my cooling issue.  The pump otherwise works fine, I don't think it's defective.  This bios is still manufacturer 0220 from 2017 and I've been reluctant to update it due to me not wanting to lose a $2k computer, but if that's the issue i'll risk it.  Any help would be appreciated.
