Nintendo Switch Active Cooling Adapter

thingiverse

This is probably not a thing for everyone owning a Nintendo Switch. <b>I am not responsible for any damage done to your Nintendo Switch or other hardware caused by this little 5 minute project of mine.</b> When playing Fortnite and other games which are squeezing the last amount of power out of the Switch, I noticed the amount of hot air leaving the console. The original fan should be able to cool the Switch and the hardware has for sure overheat protection, but I found that adding a little fan would support the cooling factor and it did. Using this adapter there is no noticeable temperature difference between the room and the vent shaft, while before if was way above room temperature. To build this adapter you need a 3D printer (who would have guessed that?) a 30x30mm fan, at least two 2mm self tapping screws to fit the fans mounting holes and a way to power it. I soldered the unused USB plug from an USB LED strip directly to the fan and covered the mess using some heat shrink. The adapter fits directly onto the switch when in docked mode. You can plug the USB in the back of the Switch Dock to hide the power cable of the fan. I have a network adapter there, so I needed to use one from the left side ports. Of course you can use another power supply or add a switch to turn the fan off, when not needed. I know this project is not designed perfectly, but it works and it looks kind of cool. If you have better ideas, then feel free to let me know and show me your results. As mentioned I just took the measurements and hacked it into FreeCAD. <b>Just a small note:</b> The top side of the adapter has cut outs on each side of the fan which match the lower Switch vent. This is on purpose. I did not want to limit the air flow from the Switch, when the fan is not active or somehow broken. This way just a minor part of the fans frame is blocking original the cooling. You may consider this, when trying to invent a more perfect solution. <b>I am not responsible for any damage done to your Nintendo Switch or other hardware caused by this little 5 minute project of mine.</b> As always FreeCAD source file is included. Happy Printing.
