On 18.07.2004, the third Version of the Hilfsdrache was finalized.
The CPU Cooler was replaced through an selfbuild Watercooling System.
The coolant radiator used was from an Ford or Opel Automobile. The other parts were an small 12 Volt pump, and selfbuild copper water cooling unit for the CPU, and an water tank (made out of an plastic tube with cover).
To get an better airflow through the main 120 mm fan, the back of the Server got 2 coverplates with holes and - for better optic - an lighted perspex plate like the one I made in large for the mousepad.
The parts of the watercooling - like radiator and water tank, were lighted with blue leds, too.
To switch the light on and off, the display holder got an additional switch.
What is not seen is the relais I build into the MiniATX Powersupply AFTER I made these pictures: From the moment the PSU starts delivering power (the Pc is powered on) - the pump also starts and therefore the waterciruculation and coolant of the CPU.
NOTE: The Server is disassembled at the moment, as it needs more work on the watercooling system (it worked one year flawlessly, but there are some weak points where it has to be redesigned).
