https://www.amazon.com/Dell-Optiplex-Processor-Heatsink-Compatible/dp/ B00DZVBJRY http://itechjsc.com.vn/techsupport/dell/desktops/op980/sm/fan.htm I've got a Dell Optiplex 980 SFF with the CPU fan missing. The fan is a hot- swap part, the above 2 URLs have a picture of the fan assembly. https://www.amazon.com/Dell-92x92x32-Fan-PV903212PSPF-0A-3612KL-04W-B66/dp/ B00HMCPITW The fan itself seems to have a part number of WC236 / G5883 and is probably used in more than a few Dell workstations and maybe some of the low-end servers. Does anyone have such a fan to spare? Alternately how likely is it that I can take a fan from another PC that's the same size and have it work in the Dell? The Dell in question is a nice system, it has one of the faster i7 CPUs so it would be a shame to waste it due to the lack of a fan. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/
