Pc fan...

Was wondering how i wire/power a pc fan to be in my growroom?

yep.. already found it maybe u can help me out with where to put the intake n exhaust... top vs bottom that is.

Intake on bottom exhaust on top THIS IS KEY for any temperature regulatory ventilation system. The idea here is hot air rises and will remain on the top 3rd of the medium warm air hangs in the middle and cold air being densest hangs at the bottom.

Placing a exhaust vent in a high quarter of your grow space will suck the hot air away from where it pools and allow it to be replaced by warm or cool air.
