Description

Thicker shroud with more room, which allows for a thicker fan to be used.

Remixed this from jass_on's thing. I just removed the grill/guard portion and increased the hole diameter a little bit. It's a bit quieter this way as the air can move more freely.

Since I'm using an enclosure it's no risk for something to get stuck in. And otherwise, it won't chop your finger off anyway! :)

Using a Sunon MF40202V2 fan.

Please post your makes and let me know in the comments what you think!
