I have an NF4SK8AA board with a crippled fan. The fan is located between the PCI/E slots and was damaged by a protrusion from a heat sink placed on a video card in one of those slots (This issue was discussed here). I've managed to use a cardboard spacer to clear the heat sink from the fan but the fan is noisy and appears not to be spinning at a full and consistent speed. It has been cooling adequately and has run in this configuration about 5 days and just did a reboot today (previously it was rebooting about 3 times per day). What I'm trying to find out is if this fan is replaceable, how difficult it would be, and where I might locate one. Any help at this point would be appreciated. Please advise if any further information is needed.
