just an odyssey of mounting behind me. On a MSI FXA890GD65 mounting the cooler per se is simple but the mounting of the fan is a disgrace. This is only possible if the motherboard is expanded. Even then, it takes a lot of patience because the manual is silent studiously. After ca.2h I had all assembled, but if I had known that before, so it would not have these manufacturers. The cooling capacity itself is outstanding. I had the Katana 3 (Phenom 965) and the Temps are u ca, dropped 20 degrees. The noise level is almost inaudible even when overclocking to 4 Ghz.
