PC Fan inside my coolidor ?

[Bubba -NJ]

Here's the photo . On the left side of the fan is the speed switch(low ,medium and high). I let the fan run for about 10 hours today and no visible problems . The DC converter I used is a Sony from an old cordless telephone that I had in my basement for some reason . The good thing about the connector end for the PC fan being soldered to the DC converter is that if the fan should burn out I can just get another one and replacement is easy - Plug and play . Thank you for your help , if not for your tips I wouldn't have this hooked up yet .
