Kalua Posted October 7, 2010 Share Posted October 7, 2010 I'm a very happy camper with the H50, with respect to temps, but not so much regarding noise. First the good. It beats my previous air cooling by 8-10C for the same fan noise level (dialed down to near silent). The H50 is set up with two (push/pull) generic 2000RPM fans, managed by SpeedFan, intake configuration through the back with exhaust out the top of the case (2x140s @500rpm). CPU is AMD Phenom II X4, 3.1gHz BE. Not overclocked (yet). P-states managed by PhenomMstTweaker. Mobo is GA-890GPA-UD3H The H50 fans are set to 700rpm, which is the point they are just below audible. Ambient is 24C. Idle (800mHz, 0.925v) system pulls 86 Watts ============================= @700rpm (silent), CPU is 4C above ambient @2000rpm, CPU is 3C above ambient Prime95 Load (3.1gHz, 1.275v) system pulls 179 Watts ============================= @700rpm (silent), CPU is 21C above ambient @2000rpm, CPU is 18C above ambient So now I've got about 10 degrees of O/C headroom to explore. :laughing: Unfortunately, I have the buzz mentioned by several others coming from the pump. I reseated the pump, and tried pressing, pulling, squeezing, etc., and it is constant. It is definitely noticeable over the fans when they are at 700rpm. I can hear it from the closed case easily from 1 meter away when the TV/radio is off, but OTOH, other than the pump buzzing, the system is near absolute silent. If I dial down the pump to about 1150rpm, the buzz is then inaudible, but temperature performance suffers. So my question: how much pump noise is expected - particularly when the noise is such an annoying buzz? I don't want to go through an RMA if the next one won't be any better.
