Designed this PCI fan bracket for my system. Figured someone else might be interested in it. Might add a fan guard if I get my fingers caught in the blades to often.

This is neat! I may give this a try when I have some time. Fan guard is a good idea, but it would also be able to remove the unit without the screws in the back for easier access to the PCIe cards. Maybe the screws already used to hold down the PCIe cards can also hold the fan bracket? I have my HL15 rack mounted in pretty full cabinet so that makes it harder to see / maneuver a screwdriver behind the system. I suppose some thumb screws may also work for quick removal.

I was thinking about that last night. I think I have figured out a way to allow for quick removal.

Does this sit up against the top of the case lid or have some room to draw air from above? Thinking of giving it a try.

Any other 3d mods you’ve done? I noticed a fan shroud that funnels airflow towards the PCI slots but haven’t tried that yet either.
