MS Surface Pro 3 Auxilliary Cooling Fan

thingiverse

MS Surface Pro 3 Tablets are prone to heating excessively, especially when doing computationally intensive tasks, such 3D editing ....... This can lead to performance speed issues such as CPU throttling. to help my tablet keep its cool under pressure I felt the need to come up with something to help. When docked the fan must not interfere, must provide sufficient air flow, optionally it should work from a USB supply ( several on dock and one on the power brick). It should not interfere with case flap stand operation in any way in use and create free air flow all around the housing for best cooling, there is an intended gap around the housing an computer back panel. I chose a 120mmX120mm cooling fan with good air flow capacity, smaller can work but more is better, fan should be quiet and the one I chose came with grills to protect fingers. the fan came with a speed control, purchased from Amazon. It is size that counts here mostly The goal was to provide extra air at the top right corner air intake and to cool the back panel and blow past the air outlet on the right side also. the ports on the right upper corner must be unobstructed and it must not interfere with dock use. the housing attaches to the fan with the grill screws on the supply side of the fan, the upper screws are a tight reach, be warned. The unit rests on 3 pads top and right side that I have added some felt pads ti prevent damage to the tablet. The housing does require supports in printing, I used PLA 210,60 with a brim, there was some clean up required. Performance has been very good. enjoy, good luck!
