A question about cooling with the Picade

It doesn’t get that hot, even without a fan. I have the Picade running 24/7 and game on it about 1 hour a day, sometimes running Dreamcast games. I never noticed the temps reaching 70 degrees, and the inside of the case never gets hot. I did stick on a low profile copper heat sink to the cpu, but that’s it. No need for a fan. I power the Picade with the official raspberry pi adapter, and power the 8 inch display separately using an old 1amp Apple phone charging brick.
