Cyberbetty Mark IICyberbetty Mark II is in fact three machines fused into one, a while back (around Y2K) we started to think about taking overclocking to a new level.
Back then everyone was using phase change cooling (refrigirator pumps) to cool their Athlons with some sucess, the biggest problem was and is condensation.
Later it became apparent that the best way to fight condensation was to keep the computer case filled with inert gas, since inert gas contains no water vapor there would be no problems.
The traditional method involves alot of non conducting paste and foam insulation which is messy, un-reliable and bulky. This is what CBII is designed to overcome, a sealed aluminium case containing three computers with a positive pressure of Argon gas.
We later dropped the phase cooling and choose peltiers instead, the current configuration uses massive 350W peltiers along with a water cooled hot side. This configuration can cool a modern AMD processor under full load to -48° C!
Both GPUs and GPUs have a peltier attached with a watercooling block on the backside, due to the size of the peltiers and our design we opted to build our own waterblocks, each of the blocks comes from the large block of copper pictured here.
The computers are powered by 4x750 Autosensing autoregulating redundant power supplies in a hot-swap configuration, the peltiers are powered by a seperate power supply to provide 15,5V which is the optimal voltage for these peltiers.
We will be posting more pictures and details as the work goes on and we get more parts ready.
If anyone wants pinout information for the Compaq 750W Power Supplies along with the pinouts for the hot swap panels feel more than welcome to contact us.
