Help hooking up my pc fan to 12v power supply

[prncssprplfrog]

I would much rather have some electrical assistance than blow up my little fan. I'm sure that many people feel the same way, but I am a little intimidated by playing with electricity.
Here's what I have:
12vdc 2-3/4" square muffin fan. has one red and one black wire.

ac/dc adaptor- (input-ac-120v 60Hz 7.0W) (output DC-12v 200mA)


I have cut all the wires & am ready to attach them.

Trial and error, try one and if it dosn't work do the other one,

Thats what i suggest. Did you get wire/eletrical nuts?

I think I have some, if not, I do have electrical tape. I put the light/ thermostat together without a problem. I'll just have to do it huh?

I guess that will work! Good luck! Im tryin to find an adoptor for my fan!

use an old adaptor from a cell phone or other phone, you have a black and red wire on the fan or I did, and on my adaptor I had a cord with a white strip on one of the wires and solid black on the other. I think I put the black to black and red to the white............duh.......I guess I should have written it down somewhere

I got lucky on my first try- it worked.
I just used an old adapter that we couldn't remember what it went to. I was annoyed when I started to look for parts for my 'bator because I knew that I had just gotten rid of a few adapters that I could have used. If my temperature does better with the fan, I will put my first (smaller) 'bator back together and find a 2nd adapter because it didn't have a fan in it.



I am going to need a place to put my first set of eggs in as a lock-down hatcher while the maran eggs progress- as they are far enough apart that the humidity might affect them.


Right now I have the fan hanging from the ceiling of the 'bator blowing down......I don't have screws to hang it from the side... Where's the optimum placement?

yup- that's what worked. I bought two of these fans from American Science Surplus for like $2.50 each. For my small incubator- they should be sufficient.... I hope.
