Tivo Bolt cooling adapter

**Update 30 Mar 2020:** A great comment by [openscadder](/openscadder) highlights the fact that Noctua makes a 5V version of the fan which can be powered from the TiVo's own USB connections! See the comments section for more. **Update:** Be sure to take note of the comment by rscottbutler in the "Comments" section! A coworker of mine has a Tivo Bolt. Apparently, the stock cooling on the Tivo Bolt is not enough, and there are many people who do various things to improve the cooling. He approached me about creating something to fit the Bolt to improve the cooling by integrating a larger fan than the tiny 40mm fan installed in the unit. He was also hoping for something that would work with the strange bent design of the Bolt. Here's what we came up with over a month of prototyping and testing. This design uses as little plastic as possible while also requiring as few supports as possible. (see Print Settings for more details on supports) To use this, you'll need an 80mm fan and four M4x35mm or M4x40mm screws. The female screw threads are printed in, so place the fan in position, screw it in, and attach it to the power supply. In testing, Mark was seeing temperatures as much as 9°F cooler. **Update:** To check your before and after temperature, go into Help... Account & System Info... System Information and look for `ODT Temp` - keep in mind that this is the "On-die temp" for the CPU itself so it will be much higher than room temp, but it's good for a before/after comparison.
