Whereas it is well-understood that the Raspberry Pi 5 runs a bit of hotter than its predecessors, maker Michael Klements has taken the issue to its excessive conclusion: the event and becoming of a full watercooling system, together with customized water block.
“I’ve constructed a customized water block for the Raspberry Pi 5, and I’ve gone all out,” the maker explains of the challenge, which is designed to be fitted to Raspberry Pi’s newest and strongest — and power-hungry — single-board laptop. “This block includes a milled aluminum chilly plate, an built-in clear acrylic distribution plate, a built-in pump, and hardline tubing resulting in an 80mm radiator and fan.”
That the Raspberry Pi 5 is an enormous step up in efficiency from its predecessor isn’t any secret, and neither is that this additional efficiency comes at the price of further energy necessities — and, thus, warmth era. Raspberry Pi itself gives a selection of two active-cooling options, a heatsink with a built-in fan and a case with the identical, however Klements’ strategy is excessive overkill.
The Raspberry Pi is housed below customized full-coverage water block, machined from aluminum utilizing a desktop CNC mill, which sits below a see-through distribution plate crammed with coloured coolant. That is pumped over laborious tubing as much as an 80mm radiator with fan, the warmth bled off, after which returned to the opposite aspect of the water block.

It is as pointless as it’s enjoyable: the Raspberry Pi 5 can function with no cooling in any respect and solely throttle below sustained heavy load, and with both of the official cooling options would not throttle in any respect. There is no denying that Klements’ strategy is efficient, although: the system was examined to peak at 32°C (89.6°F), lower than half the temperature of the identical unit working below the official Raspberry Pi Energetic Cooler.
The construct is documented within the video above, with extra particulars obtainable on Klements’ weblog.
