Does anybody know an online electronic store where I can find the same size and dimension fan that comes on the AE heatsink?

A manufacturer and part number would be nice too.

you are looking for something that is seen commonly in computer video cards. try Radio Shack of your local computer store.

I belive that Reddy is selling the same fan now...(minus the heat sink)

KT Hobbies has them right now

These fans are all 5V fans but most are larger than the tiny one that associated uses.

Perosonally I use the 1.6" sq size fans and they work well.I use this one
