Having read many reviews of the Arctic Cooling Freezer 64 Pro, I was lead to believe it was very quiet. I wanted rid of my water cooling kit to make room for more drives, and this evening I sat down to fit the Freezer 64 on my AMD X2 3800+... To my horror I noticed the fan used a 4-pin connector used for PWM, a connection my DFI Lan Party SLI-DR does not cater for I knew however the 4-pin connector can be fitted on a 3-pin header, but unfortunately on the DFI the cpu fan header is placed right next to a capacitor, and thus the 4-pin does not fit So I used another 3-pin fan header on the board and it works. However. To me the fan sounds noisy, it's running at 2200rpm constantly and it keeps my X2 3800+ (overclocked to 2.4Ghz) at a very cool 32c idle. Now considering this, to me it sounds like the fan is running at full speed even though it dosn't need too. Is it because it's not on the cpu header? I know I've came from a quiet water cooling setup, but people who have this cooler say it's very quiet, and this isn't.
