Im thinkin of getting two 120mm fans for my hood.... when my VHO are on my temps are 84 max and that is just with 4 lamps....im adding 2 more soon
would those fans help out alot?
blowing in or sucking out?
Yes. they would help alot. put them on the ends of the hood blowing in.
Removing the glass tops, and a fan blowing on the sump water would also help for a few degrees. I dunno if you have already done this though.
