That's a cool idea. I'll see if we have any laying around the house (I know I have some in a box somewhere) or I'll buy an adaptor like mentioned above.

As for the fan, that was the only fan the radio shack near me had in stock. I take that back, there were three but they were all similar.

I wouldnt consider paying that much for a radio shack fan. Check out tigerdirect.com or newegg.com they will have a much better selection for sizes at much better prices. You should also be able to find a 12v dc transformer at those places also. or you I have heard of people using an old cell phone charger which is lower voltage which will work the fan will just spin a lil slower.

The actual fan says it's a 0.32A 3.84W...not sure if that's important.

Also...I've never installed one of these, but the salesman at radio shack said I could just hijack my wiring on my heat tape to get it to run. I figured that wouldn't be a problem since I'll be using a Herpstat 2 on it. I was going to plan on sodering it to the wiring coming off my heat tape. Is that alright to do?

it's a 12 volt dc motor. so if you take the 12 volts and times it with the 0.32 amps = 3.84 watts. volts x amps = watts. ohms law. did it come with a power supply.
I wouldn't run it off of the heat tape. mine is ran thru a light dimmer, so I can control the speed of the fan if needed. did it come with a power supply that will change the 120 v ac into 12 v dc?

It didn't come with a power supply, just wiring. I purchased this today to run it off of: http://www.gandermountain.com/modper...arger&i=414669

I like it!!

You can skip the rheostat with that thing. Just click in the voltage to change the fan speed.

Yep! That's why I liked it! If the fan is too much, I can half the speed pretty easily. If that's still too much, I have lamp dimmers around the house that I can hook up to it. I'll be finishing up the incubator tonight so I can test it until I get eggs.
