How can I hook up spare computer case fans to a wall outlet to cool my home theater equipment?

Question

I have a bunch of spare computer case cooling fans (120mm) that I want to use to cool some of my hot home theater components in an entertainment wall buildin. Going to specific HT cooling sites, the fans did not look much different than the ones used in a computer, but they cost a lot more and were capable of being hooked up to wall outlets (using some type of adapter, transformer, etc.) Can I use an old computer power supply? Does it need some type of jumper? Is there some type of transformer/adapter that I can plug into?

Thanks

Yes you sure can!

Look carefully at the labels on the fans.  It should indicate which DC voltage and the amount of current (amps) it needs.  Go to an electronics store (Radio Shack or similar) and buy a plug in power supply with the correct voltage and has an amperage output that matches or is more than what the fans need.  Hook them up to your fans.  That's all you need to do.
