Surface Pro Mini Fan Mount (40mm)
thingiverse
This is a 40mm fan mount for an extra cooling fan for the Surface Pro. The mount clips over the back of the Surface Pro and provides extra cooling for improved performance. I use mine on a Surface Pro 7 i5, but it should also work on at least the Surface Pro 4 through 6. I used a Noctua NF-A4x10-5V-PWM fan, which comes with a USB adapter and can be plugged into the Surface USB port. Other 40mm fans will probably fit as well. You will need 4 standard fan screws to attach the fan. The holes are countersunk for the fan screws included with the Noctua fan. My overall power limit increases from around 10W to around 17W, which provides a significant boost in performance. This was designed in FreeCad and is loosely based on skiiermike's fan mount (https://www.thingiverse.com/thing:1710600). Most aspects of the design are parametric, so it should be reasonably easy to adapt to a different fan size.
