Makeshift ventilation fan...

Low on funds, decided on a temporary fix. Took a 4" aluminum elbow fixture, used foil tape to mount a 5" fan to the end of it, cut a hole in the ceiling.. and voila. It makes my room about 5 degrees cooler with no intakes yet. So actually it's quite perfect.

Haha, thats funny. I did the same thing but hooked a filter up to it. Fan is in the big part.

Works well but its a little loud.

I see no probl.... well i see lol.... i'll just close my eyes.If it works and that all that fits into your budget, perfect!

haha.... whether or not I said it was efficient is a WHOLE different story!
