Thanks for the Advice. I changed the speed profile using thee Gigabyte SIV app, and set the pump to run at 3000rpm, and it is now silent. I think that at 100% speed 4500rpm is just too fast, and with the lower speed the CPU seems to run cooler, 23oC at Idle and 63oC at max load (6700K O/C @ 4.6Ghz)

Hi Just put in a H45 AIO Cooler in my Gigabyte Z3 Gaming system, and i have noticed that the pump is making a whining noise which is coming from the bottom of the radiator, where the hoses go in. I thought it might be the fan, but i disconnected the Fan and the noise still remains. The Pump is connected to the CPU fan header, and the Fan is connected to the CPU_OPT header. I've checked the RPM of the pump and it's running around 4500rpm all the time. Is there a way of quieting the pump down. Cooling is fine 23oC at Idle and 64oC fully loaded (6700K O/C @ 4.6Ghz) Just the whining noise that is driving me mad.
