Hate to necro an old thread but the Big Typhoon VX is perfectly compatible with am2+ and am3 motheboards I'm using a VX to cool my FX-8320 on a GA-990FXA-UD3 motherboard the VX uses an AMD style retention clip and not a pushpin or screw down type like intel.
BTW my Typhoon is good for letting my CPU reach 4.7 ghz, that's 1.2 ghz above stock not bad for an old cooler.
