Just like we suspected, our fellow Australian hardware examiner TrashBench is up to shenanigans again. Not too long ago, after putting a graphics card in the "wrong" place for much better cooling results, he's ... thinking bigger, let's put it that way. He took an old 4-kW outdoor radiator-fan unit from a split air-conditioning setup (sans gas) and hooked it up to a water-cooling loop to assess its performance.

He kicked off the video with his best impression of Crocodile Dundee, and set out to rearrange the unit for the task at hand, as he only needed the actual radiator, fan, and pump. Most of the fiddly guts were taken out, and casters were added for convenience. TrashBench then added a bog-standard reservoir to the main enclosure.
