Need a replacment fan for AM2 HSF

I have a anthlon x2 that the fan is starting to go on and I want to replace it anyone know what size I need and also can I use any kind of fan or does it have to be made for a CPU cooler fan

Instead of spending $10 on just a fan you might as well just get a new cooler. This Cooler Master Intel Core i5 compatible Hyper TX3 Socket 775/1156/AMD is a great deal at just $20 shipped!

Make sure you clean off the old thermal paste with isopropyl alcohol and let it dry before applying new stuff (supplied). When putting the new thermal paste put a dab right in the middle, not too much just the size of a large grain of rice.
