PC fan set up... This is new though

I have a 12 volt pc fan. But nothing I find is 12V. Can I use two 6v chargers to run it? Will it fry it?

No I wouldnt do that for that chance of maybe coming home to a burnt down house. You can buy or find for free a AC to DC converter 12v output pretty easy and cheap. Or depending on how much heat you are producing just run it off the 1 6v and see if that keeps your temps solid and stable.

Went to radio shack and got a 12v adapter. Fan is working. Seems slow tho. Gonna look into a better fan now

120mm fan and depending on size, 80mm exhaust fan or just a hole. Which I am currently using in small CFL grow box.

Fan is used as exhaust. Just a hole for the intake.
