fans

[cowfishrule]

getting ready to put together my light strip this weekend.
my mh will be ready to go, and im also getting my no flourescent ready.
my question is- i was going to put in 1 fan for exhaust. dont know if it should be a 3" or a 4". the fan has to be almost dead silent, as i'm getting crap from the mrs about the noise from the fans on my pc lights.
can anyone recommned a fan/brand? i would be putting them on the same timer as my actinics.

Go to pricewatchDOTcom and look up ultra quiet fans for a computer, get the biggest fan you can get. Id also reccomend getting 2. If you want, ill tell you how to hook them up to a std wall outlet with a schematic.
