The Raspberry Pi is a low-powered mini computer with a 700 MHz ARM11 processor. You can safely overclock it to 1 GHz. But if you want to get really crazy and go higher than that you might need a custom cooling solution.
Or maybe you just want to build one because it’d look awesome. That seems to be the driving force behind this water-cooled “Wet Pi” project from bit-tech forum member Phame.
There’s no reason to use water to keep a Raspberry Pi cool. It just doesn’t run as hot as, say, a high-end gaming computer.
But Phame decided it’s be a fun project anyway, and after a few months of work, he’s published photos of a custom case with neon-pink water pumped to three of the hottest spots on the board to keep it from getting too warm while you’re using the little computer.
The water pumps also draw their power directly from the Raspberry Pi board, so you only need a single power adapter to power this system.
