Ok, so I have been bored today. Was thinking of making a custom shroud for my graphics card. I want the air to blow through instead of down onto the GPU. So, doing some quick CAD sketching it looks like a 50mm fan and a 40mm fan will be just stand about 2.15625" tall on the PCB. Would have to use a 40mm to sit on top of the power connectors. My guess work puts that as a triple slot cooler. Question is if this would be beneficial or not before proceeding. I only have a junk 7600gt and my 4890. Dont really want to destroy my 4890 leaving only the drastically different 7600. With the 4890 I could just mod the stock cover to accept my fans. 7600 will require complete fabrication. Would the work be worth it? Can a 50mm and 40mm fan blow enough air to cool the HS better than a stock fan? It would allow good cooling for SLI or CF, but the problem is the 3 slot design. Most mobo have a single slot between PCI 16 slots so dual slot can utilize CF/SLI. So, my design would leave a slot open but at that point, provides nothing over running standard cards in SLI since there would be space between the stock cards also.

Probably stupid and wont work huh?
