Scultpor (56)

You can see the voltage regulator I used for the CPU cooling fans and pumps. I had to fabricate/install a heatsink to the regulator as it wasnt designed for this purpose and was overheating. I later realised that regulating the speed of the fans/pumps was a terrible way to control the voltage. As explained in my previous post, a better way was to shut off the TEC's themselves when too cold.
