Cooling fan duct for the NVIDIA Tesla K10/K20/K20M series graphics card adapting (2x) 40mm cooling fans in a relatively compact design.

While building a new media server and virtualization machine I wanted to add a little extra power for transcoding and computation, but with graphics cards being as crazy as they are, I turned to the Tesla line. These K20M cards are pretty easy to find for reasonable prices, and still have some good life and purpose left in them. The K20M however is inherently a passive cooled card as the workstations and servers they lived in had heavy duty cooling pushing through the chassis, which is what led me to create this cooling fan duct for mine. I am certainly not the first to create this, and there are designs out there for other models which gave me the inspiration.

I prefer to orient this piece with the fan mounts facing down as it is the widest part of the print for the most stability on the bed. Depending on your overhang settings this will print supports from the bed up the interior of the duct to support the cable bump, and from the side of the duct to support the screw mount plate.

I haven't tested this out yet, but it does look as though it may be possible to have multiple cards stacked together and still make use of this adapter. I'm currently waiting for new PCIe riser cards to come in which may allow me to test this theory.

I have recently updated my workstations and will no longer need these fan ducts and thus will not be maintaining or updating the design any further.

Cheers!
