I just received my fan from digikey (tried newark as well and got the same backorder status). I ended up running into a problem with my fan. Not sure if I ordered the wrong one or if I got a dud. Do you know what the part # is of the one you ordered? I posted in the ep2500 thread but got no response so far. Hopefully you have better luck than I am currently....everyone seems to have no problem with this mod except me.
