Cooled phone holder

I use my phone as a hotspot for my desktop PC a lot due to location circumstances, however my phone would overheat while charging and tether, so thus, I made a stand with a 140mm PC fan. For me, I've just went basic and connected it to my PC on the motherboard, but there might be better options out there.Any regular mounting point 140mm fan will work, regular screws that come with the fans will work.
