The PSU in the Sugo SG05 is a FSP300-60GHS which some people, including myself, find a bit on the noisy side. The idea to replace the PSU fan has been bugging me for quite some time and a couple of days ago I sat down and did it.
If you want to see what is inside the FSP300-60GHS, there is a good review at http://www.hardwaresecrets.com/article/757/1. The PSU fan is a Protechnic Electric MGA8012XS-A15 which, according to http://www.silentpcreview.com/forums/viewtopic.php?t=29247, has the following specifications:
A more serious concern was the possibility that the HFF-1N08N might have a higher starting voltage than the MGA8012XS-A15 and might not start to turn straight after turning the computer on but, fortunately, this was not the case. The HFF-1N08N starts turning even if the PSU is jump-started on its own.
The replacement of the fan is rather straightforward, but a neat job requires some soldering skill as the MGA8012XS-A15 wires are soldered to the PSU board. Of course, one should also be very careful not to touch any of the connectors of the single enormous capacitor.
The modified FSP300-60GHS is much quieter and has been running for a couple of days without any problems.
