I have recently installed the Scythe Zipang on an AMD Phenom II X4 955 / Gigabyte MA790FXT-UD5P System. I am using a Coolermaster Silent Pro M600 for power supply.
Generally, the cooler works fine. However the following problem occurred: From time to time the fan of the Zipang is not moving while when the computer starts up (mostly after beeing turned of over night). I have to open the case and rotate the fan a little bit manually. After closing the case and restarting the system, the fan is rotating normally. Haven't had those problems with the original AMD Cooler.
Opening the case each time gets a bit dull. Help is therefore very much appreciated.
