Thanks videoman, I need 5 Volt fans and how do you get them to turn on and off when it gets hot?

A quick whip around on e-bay shows that the 5 volt fans are way more $ than the 12 volt.
i could not find a 5 volt fan controller - though they may be there.
I did find this It will boost your 5 volt to 12 but you will be limited to 2 amp current draw

Thanks, I guess I might add a 12 Volt Power supply to the enclosure to run the fans and controller.

Why not use a 5 volt to 12volt DC regulator to boost your voltage to run your fans as mentioned above by @videoman3857 , The fans draw very little current and is a good alternative to adding a second power supply

1 of my control boxes has a 5v power supply in it and I used a step up transformer to boost the 5v to 12v for the fans and have no issues. It is much easier to get 12v fans than get 5v ones, also having all 12v fans you can have spares and swap them easily.

Might sound silly, but for my vents I just use 90 degree pvc elbows... Looks a bit rough but does the job. And fans fit nicely...
