Your mistake was using stagnate cooling water. Next time, drill a drain hole in the bottom of the case, and keep a supply of fresh water going in. Be careful however, because the waste water will have all your data digitally encoded upon it, and the drain operatives might get to know your secrets.
When I was at school, I was charged with relaying
the electrickery from one end of a corridor to the stage. I supplied the wire. Single strand 3 core rubber - that I'd got off a dump. It just reached.
I wired the stage with the schools rheostats supplying big bulbs in biscuit tins. All these 'dimmers' were totally open!!! and the multi-leaf sliders sparked gently until I rubbed my pencil on the windings. On one bright scene, the wire - hanging from coat hangar to coat hangar along the corridor - started to smoke. On the day of the play, the parents all remarked how good the lighting was, but what was that
smell?
