get 939 pin
hahaha (forced refferal)
OK, not to worry, but thing is, if you cant get 939 pin FX, get 939-pin athlon-64, and get board on VIA K8T800 PRO chipset.
get the zalman CNPS7000- CU series cooler, though they are heavy (750 gms) i believe, but looking at this board, they'll surely fit as transistors at one side arent high enough, as the cooler is smaller in width at bottom, and becomes wider at top.
they have qualified motherboard list as well, see if this mobo qualifies.
