EVGA makes ‘all-in-one’ cooler with liquid nitrogen
EVGA showed an all-in-one partially closed circuit cooler using liquid nitrogen at the Computex trade show in Taiwan. The cooler is intended for users who want to go through extreme overclocks and don’t want to manually top up the nitrogen.
The cooler has been given the name Roboclocker and was developed by two overclockers, Vince Lucido and Illya Tsemenko. The GamersNexus website reports to have attended a demonstration of the cooler. Lucido, also known by the nickname K|NGP|N, is able to circulate the liquid nitrogen with the Roboclocker, whereby the degree of circulation depends on the set, desired temperatures. In the system, used liquid nitrogen passes through a number of flexible steel pipes and can also leave the system. This makes the liquid nitrogen partly reusable, so that an overclocker does not have to pour nitrogen into the system every time.
The cooling system consists of two tanks for liquid nitrogen, one tank serving as the nitrogen input while the other is for the collection. The input goes through a steel pipe and an input manifold to two valves: one valve is for the CPU and the other for the GPU. The valves can be opened or closed directly via a 12V rail, but this is also possible via temperature measurements on the sockets of the CPU and the GPU. About 75 percent of the LN2 can be collected again.
The cooler isn’t exactly an easy-to-use consumer product, as EVGA had 300 liters of liquid nitrogen available for a desktop system with the Roboclocker. The cooler was used during a record attempt with a system with an Intel i9-7980XE Extreme Edition and an Nvidia Titan V-gpu. The CPU reached 5700MHz at -95 degrees Celsius and the GPU ran at a clock speed of 2300MHz at -80 degrees Celsius. This resulted in a 3DMark Fire Strike score of 36,551, a 3DMark Fire Strike Ultra score of 10,527 and a result of 17,441 points on the 3DMark Time Spy benchmark. The Roboclocker is said to hold some overclocking world records.
