The guys at Puget Systems have been at work again creating another completely silent gaming computer. Like the first design, this computer is completely submerged in non-conductive mineral oil.
The biggest design improvement in version 2.0 is the newly designed acrylic motherboard tray. They also majorly improved the cooling system. The new radiator sits on the back, and mounts directly to the aquarium. They mounted four Antec Tri-Cool fans to the radiator. Running them at low voltage, they achieved a very quiet operation. The loudest part of this system is the bubble bar!
How well does this setup cool? AMAZINGLY well! In this system, we put in the best hardware — an Intel QX9770 overclocked to 4.6GHz, 8GB of DDR3-1600 memory, and a NVIDIA GTX280 video card. It ran at 50C under full load, and that was with our fans on the low setting!
In this system, the pump and hard drive (solid state) are both submerged. Using a special bracket, we are able to secure them both in the oil.
