Well I have owned an Intel 1.6Ghz Atom mini-itx motherboard [D945GCLF] for little over a week now and already the chipset fan has failed. I came home today to a room smelling slightly of burnt electrics and a very, very noisy chipset fan. As I have been testing the new system out as the future home of photogabble it was already set up as a server so I remote shelled into it and ran the “sensors” command to see that the north bridge was running at almost 70degC and the fan which normally runs at 6000rpm was reported to be running at 2700rpm and decreasing. I shut down to check the fan wasn’t being impeeded in any way before restarting the system. The fan was quiet and running as normal to begin with and then a few minutes it began to whine and the sensors app showed the fan speed slowing down until all of a sudden it stopped. A very quick shutdown later I have removed the chipset fan and am looking for a replacement.
It looks like the fan is a 40x40x10mm standard build so I am going to be looking for something like the SUNON KDE1204PFV2.
I found infomation on this here, here, here and here.
