Oh dang. Thanks for the input guys.

. I will probably get another fan and do a push pull. The room is a small 10x8 in the basement. I will try to get air blowing from the basement into the room and vented out... problem being I would want the basement door closed (access is from the outside of the house to the basement. so the air wouldn't be as cold as outside.
So the red circle is the fan I already have. And here is the "plan". So I shouldn't really have to worry about condensation on the rigs?

The fan by the gpus will be the more normalized/ambient air from the basement. (or would it work better to have the fan by the gpus pull air to the basement? It will probably be a smaller fan. (The window fans are 14" 1400cfm, i think. The fan by the gpus will probably be a small house style fan.)
