I currently run an 100 watt LED setup that uses five PC fans as well. I wired the whole thing myself, using as much safety as possible. I use two PC power supplies at 650 watts, and 550 watts. I've modded the insides to bypass the power switch, and to clean up the excessive wires that are mostly un-needed.

So I'm here to help, please feel free to ask!imp:

P.S. PC power supplies are very lossy under load, meaning the more you run off one Power Supply Unit (PSU) the less voltage that PSU can produce on it's 12V line. (That is why I use two, and they are so high in wattage.... also the 550, and 650 rating is for ENTIRE wattage, and the 12V line is only getting about 50% of that total in most situations.... no matter what it says on it's sticker..... I've done excessive testing, as I am a computer repairman, and have tons of old PSU's lying around)

Wall-Wart: A power adapter, the type you plug into your wall, and will have a cord running off it, or possibly terminals where you can attach wires.

NOTE: Wall warts in the 12V DC variety are not easy to find over 500mA..... just so you know, each normal PC fan takes 140mA-170mA.......
That's very useful to know. Thank you for the info and the offer for help. I do have one question, have you carbon filtered any PC fans for exhaust?

PC Fan Power Supply I found a site with power cords for PC Fans: Dayton Blowers: REPLACEMENT 6' POWER CORD FOR AXIAL FAN - Fans, Blowers & Ducting - Environmental Control - Discount Specialty Farm, Greenhouse & Garden Supply Store - Horticulture Source . Box Layout: Flower Chamber - 3' x 3' x 6', Mother Chamber - 1.5' x 3' x 4', Clones Chamber - 1.5' x 3' x 2'. The only reason I had not planned to do PC fans was the power cord for them as I read that while it is easy to wire something like an old car Rating: 5
