Title: Drum fan cooling - 12x 6990 rig. Post by: mackminer on July 06, 2011, 02:21:33 PM Hi,
I want to place this over the rigs sending air right down to them. I'm wondering is 24 inches too big. I am in a garage and it's not airtight at all. Alot of the air will be recirculated by the fan but it's usually cooler anyway when the fan blows it down again at pressure isn't it? Title: Re: Drum fan cooling - 12x 6990 rig.

That's what I did with my 16-card rigs.
