idea: wind tunnel cpu cooler

post #1 of 5
Thread Starter 
has it been done before? my idea for the shroud is just cardboard and tape. and the geometry could be varied to accommodate the space you have to work with. a push configuration would probably work best

check out my excellent mspaint schematics

All the Dell desktops we use at work use something similar to this. Only difference is it uses one 140mm fan

Wonder how that would do with 4 GT's!

Yeah, as ttaylor0024 mentioned, this is how a lot of dell desktops implement their cooling--generally a passive (and massive) CPU heatsink with a shroud/duct connecting to a front intake fan--in the dell desktops we have at work, I don't think there's even a rear exhaust fan.

I can't imagine this being more efficient than a fan directly on a CPU cooler--I would assume dell and the like go with this sort of design just to reduce the number of internal fans that might go bad and require a warranty service.

It's a fun project, but I imagine you'd achieve better temperatures (and less noise) with a fan on the CPU cooler and a single exhaust fan.

you could even do more fans if you had the room. or stagger them. hell, you could even have them on "top" of the heatsink- the point being to increase the pressure as much as possible.

you could have more than 10 fans with this setup. possibly 18 total.
i think the energy carrying ability of the heatpipes would not be able to keep up and that would limit you. but there seem to be a lot of possibilities here

anyone know how diminishing returns work with fan pressure?
