The ROBOCLOCKER was designed by KINGPIN and Illya "TiN" Tsemenko, and adopts some ideas from the liquid (water) cooling realm for LN2 cooling. The cooling process is automated through a closed loop system and requires no human intervention for pouring the LN2; it is instead drawn from a primary tank. Software is used to keep both the CPU and GPU(s) cooled to the desired temperature while leaving the operator/overclocker free to focus on other activities. And since this is a closed loop solution, it "uses a lot less LN2" according to KINGPIN.
The benefits of such a setup are readily apparent. For starters, there's less LN2 waste, as the nitrogen gas is collected via a secondary tank. The control system, which includes a laptop that connects wirelessly to a custom controller, will automatically respond to cool the hardware down to the desired temperature. So, when temperatures naturally rise during an intense benchmark run, the system responds appropriately to maintain the desired temperature.
KINGPIN says that the ROBOCLOCKER has already broken five overclocking world records in 3DMark and will likely continue its winning streak as the system is further optimized and improved. It can be connected to one processor and up to four graphics cards in its current configuration.
We should mention that this is by no means a consumer-grade system. This is just something that KINGPIN and TiN have been working at EVGA on to help further advance their overclocking achievements with minimal fuss. It most definitely is a rather impressive achievement, although we doubt you'll be see anything on the commercial front for a device of this type anytime soon.
