A kind of funky fan shroud for a Nvidia Tesla P40 that cools not only the card at a rated CFM but also blows air into the next PCI slot for 10gig networking, HBA, etc. PWM controller makes the fan basically silent in a full tower case.
Use Small M2 Screws, Print without supports preferably in PETG.
