BIOHAZARD Computer Systems, a niche US ultra high-end enthusiants' PC vendor, seems to aim higher than Alienware or VoodooPC, both now absorbed within Dell and HP respectively. Its rigs, going by names such as Nuclear Winter (the freeze ones) or Armageddon (chilled liquid cooling) provide some unique cooling set-ups.
We just caught a glimpse of the newest product, Rapture - from the outside, it looks like a modded Lian Li full tower case, but inside is a whole different story. We're talking about one of the first serially-produced multi-head freezer-integrated casings here, weighing up to 40kg in full configuration.
The bottom of the casing contains a huge compressor system with its own PSU besides space for the PC's own power supply. The supercooled evaporator pipes above extend to provide up to four heads for freezeblocks, handling up to two CPUs and two GPUs. The evaporators themselves are custom designed and installed in the cooling system. Standard configuration is 1 CPU + 2 GPU evaporators, but this can be customized to 2 CPU + 1 GPU, 2 CPU + 2 GPU and so on.
BioHazard claims the rig operates the CPU at -20degC with each GPU operating
at -25degC. At these temps the system is able to
handle 550 Watts, with wattage tailoring possible, depending on the desired temperature. A temp monitor with several preset levels can automatically shut the system down at certain presets.
You can see the most recent "beta version" here, still a bit unpolished, with a shot of the GPU freezer head too - the maker claims the final Rapture cooling system will give a 5-15 per cent cooling gain over standard phase change units on the market, with that much less noise along the way as well.
If it does what it promises, Rapture should bring easy supercooled multihead overclocking without the hassle of drilling and creating your own stuff - an everyday deskside 4.5GHz dual-CPU Skulltrail freezer PC, for instance? We'll be checking that out soon. µ
