Keeping the IPad cool

[Lindaubry]

I have been looking online for a small fan or device to keep my iPad Pro cool while playing a graphic intensive game. I did not have a heating problem with my ipad 4 when playing the same game. Does anyone have any suggestions as to a specific device or favorite, I am not sure which one to get. I would like the simplest one possible that works. There are several fans that can attach to the back magnetically and there is a small passive cooling device (about 2”x3”) that attaches to the back, requires no power. Any input would be greatly appreciated.
