Yeah i'm using a Cw3000 circulator/cooler and its got a pretty good little pump on it.

Stupid not to put clips or ties on though, would have been far worse if it was a tube pipe as that sits above the electronics and the cabinet has plenty of holes there, close call i think.

Its been on all day and no more leaks though so i think i caught it.

Made a few cuts, turned the lens over the right way, will be fitting current meter tomorrow so i can check max safe power level to use - limit is 20mA for my tube.

Its fascinating to watch, great fun.
