"Droomde al half van grote Gamma alu profielen van 2 of 4 meter lang met lengte ribbels bovenop waar water doorheen loopt vanuit een tank met een pompje (een kant beetje hoger zodat het van links naar rechts of andersom stroomt door de gleuven) en de bordjes met de chips omhoog en tegenaan geklemd."
google translate:
"Dreamed half of large Gamma aluminum profiles 2 or 4 meters long with longitudinal ribs on top through which water flows from a tank with a pump (one side a little higher so that the water flows from left to right or the other direction through the slots), and the boards with the chips up and clamped against it."
I wonder if the X1/X3 heatsink could be adapted to work. I have a bunch of them around the office, just not the time/expertise to try and make a mounting bracket.
