Hi guys,
Recently I replaced my motherboard MSI P67-G55 for a Gigabyte Z68XUD3H. using the same CPU cooler (Corsair H60) however I just can't seem to lower the pump speed as it stays around 4500RPM and makes a tremendous grinding noise.
Back on my old board, I was able to use MSI control centre to drop it to about 3000RPM, absolute silence with good tempts.

Right now the CPU FAN gives me 4300RPM, the PWM FAN gives 4500RPM and they make the pump grind like crazy. I've tried using Easy Tune 6 (I see the 4500RPM, but there's no option to adjust it), Speed fan 4.49 (same thing as ET6) and changing the Smartfan setting in BIOS to 'Silent'.

Nothing seems to be working, so I took a stab in the dark and hooked the 3pin pump to a molex adapter onto the PSU, its much quieter now but idle tempts shot up to 50C (and slowly rising, scary... usually its around 25C).

Google really hasn't helped much either. Can someone please help me out here?
 
Hello... "grinding noise" in a liquid pump means there is air in the coolant supply to the pump... elevate the coolant supply and lines well above the pump to "bleed" the system for a while... if air has become "microscopic" in the coolant, you will have to let the system sit quiet for a while, till the air releases from the coolant... Once you get rid of the air in the system/coolant, re-evaluate system conditions, pump speed, temperatures, etc.
