This passive heatsink works really well for the Raspberry Pi. I've had RetroPi running a Gran Turismo 2 AI Race for 3 days and the CPU temp maxs out at 50degress C. It also feels really nice in the hand and feels like it protects the Pi. I feel I can slip this in my pocket and take it over a friend's house for some retro gaming. It gives a really nice aesthetic too. Highly recommended.
