Yeah but I'd never build a PC where the components that generate the most heat actually suck the warmer air in from the top of the case and vent it out the sides. The way my tent is set up with 3 stock Vipar panels I've got 10 pc fans moving 250cf/m of hot air from the top of my tent and venting it out the sides.
This is making my 4" rvk extractor fan (running at half speed rate of roughly 55cf/m) less effective at removing the heat from the tent. It also means that the panels are venting hot air onto each other from the sides.
I can't help feeling it would be at least as effective but probably a lot more if the panels were an integral part of the tent set up and actually contributed to the whole basic premise of getting a lot of cooler fresh air in from the bottom of the tent and pumping it out faster to maintain good cooling and negative pressure in the tent. The cooler air flowing through the panels must be better than recirculated warm air and if drawing particles in from below is a consideration then it is pretty easy to cut some decent PC filter mesh to fit the panel intakes when I'm fitting 35cf/m custom fans which will make up for the mesh restricting the airflow in.
