I have built a stealth cabinet however im running into a problem I didnt expect and that is temperature. Temps got up to 95 in the room yesterday. ambient is 70 so there is an obvious problem.

My room is 1' by 2.5 by 3.5 and so i though a 60cfm computer fan would work fine.
right now there is only one intake but im drilling another hole today.

my question is should i just by a nice inline fan and risk it being too loud for the stealth grow or do more computer fans.

this cabinet literally sits in my room so the passive air intakes have to be light proofed.

Well a fan should take temps down a few degrees and you will need a fan it their anyway so try that first and see the outcome.

Point the fan at the lights if the plants are too young at the moment.

If you go the inline route I'll warn you not to buy this type:

http://www.amazon.com/LEDwholesalers-GYO2402-6-Inch-Hydroponic-Booster/dp/B003YFADW8/ref=sr_1_2?s=lawn-garden&ie=UTF8&qid=1366761764&sr=1-2&keywords=6+inch+inline+fan

I know it's a 6" but they make a 4" also. I bought 2 this winter and they lasted hours apiece, then just ceased working.

Get one of these or similar http://www.amazon.com/Active-Air-Inline-Fan-165/dp/B0050C2SZI/ref=sr_1_1?s=lawn-garden&ie=UTF8&qid=1366762045&sr=1-1&keywords=4+inch+inline+fan

And one of these http://www.amazon.com/Hydrofarm-ACSC-Fan-Speed-Controller/dp/B003URBQ1M/ref=sr_1_12?s=lawn-garden&ie=UTF8&qid=1366762045&sr=1-12&keywords=4+inch+inline+fan

Just my experience and opinion. Lots of people get the $25 cheapo to work, but lots just have them go dead in the water like I did with almost no use. If noise is an issue spend a couple$ more and get a 6", they run a ot quiter.

Well I meant try using a 6 inch oscillating fan then check the temps and see where you're at.

Go to Home Depot and buy a 4" duct booster fan. About $20.

Y dont u just make an exhaust, and place a small mini oscillating fan in the box or at the entrance so u can move air around the bulbs and canopy. If u can, crack your window in your bedroom open a bit. very easy fix.. Just go do it

I have opted for a way overside inline fan with a speed control like aimaim suggested. they had a good deal on a 400 cfm one and i figure ill be able to use it if i decide to move up.

your always going to have high temps is you dont have an exhaust you need to take all the stale hot air out and replace it with fresh air
