This is a fan upgrade i printed for my Dell Precision T3420. I lost the original shroud that came with the system and cooling suffered alot with that. So what i did is i modeled this after some of the older Dell Optiplex systems that had a centrifugal fan that blew hot air out the back of the system and made it mount to my existing heat sink.

NOTE: This fan relies on having the guts from a Delta BFB1012H cpu fan assembly. That was a very popular offering from the 390, 790, 990, 3010, 7010, 9010 and some newer sff systems. Not confirmed to work with the Foxxconn fan assembly but you can try it.

Also you will notice it will only allow you to screw down three of the cpu heat sink screws (since the 4th was removed completely) i screwed the two across from each other then the third just tightened a little bit. after alot of stress testing it proved to work just fine

This is only my second design using Fusion 360 so any feedback is appreciated!
