Raspberry Pi gets UK made water cooler


The Raspberry Pi is supposed to help teach kids how to code, but one Londoner (Phame) has used it to learn how to fabricate a water-cooling rig, after building a liquid-filled radiator to cool his Pi.
Why? You may ask. The device can certainly be overclocked, and the Pi Foundation says last year added a “turbo mode” that doesn’t void the warranty. The post announcing turbo mode says “We are happy that the combination of only applying turbo when busy, and limiting turbo when the BCM2835′s internal temperature reaches 85°C, means there will be no measurable reduction in the lifetime of your Raspberry Pi.”


Water cooling could therefore come in handy to keep the CPU temperature lower for longer, enabling more use of turbo mode.
Phame, is not concerned about how it looks, his motivation seems instead to be a competition and the challenge.

Why am I doing this project?
I hadn’t been on bit-tech forum for a while, and was one day browsing the site looking for inspiration to get me to mod/build a new case. I came across Combatus post about the competition, the first thing that came to mind was… “why not water-cool this thing?” – That became a problem, as I started to look at jrs77 (thanks by the way) model of the RPi and throw some modelling ideas on CAD, it quickly became apparent that the thing was a lot smaller than I first anticipated. Not to worry I thought, i’ll give it ago so that’s where we are.

More details of the project, complete with other pictures, can be found in forums- bit-tech thread, link below.
Towards the end of the thread (on page seven) are pictures, like the one below, of the completed beast.

What you’re looking at is a coolant-filled radiator with twin pipes leading to a water block that sits atop the Pi’s CPU, LAN controller and other components. The rig sits in a frame that houses a tiny British micropump drawing current from the Pi itself, just a the Pi guys intended. The frame, water block and radiator were all custom-made. The radiator even includes custom etching on its interior surface.
The thread doesn’t, sadly, say if the Pi runs with this rig attached. Phame’s also posted a video, here, of the cooling rig in operation.
