Diamond-infused watercooling coldplates for 2,300W Nvidia Rubin drop temps by up to 22C

What happened

Frore Systems has introduced its bespoke LiquidJet Diamond liquid-cooling coldplate series that operates with a diamond surface combined with a multi-stage 3D short-loop jet-channel microstructure to address precise hotspots on next-generation AI accelerators, such as AMD's Instinct MI400 and MI500-series, Nvidia's Rubin, and beyond. Unlike Nexus, which integrates multiple coldplates into a large cooling assembly for several processors, LiquidJet Diamond is an individual GPU (a chip built for many calculations at once, used for graphics and AI) coldplate, albeit a bespoke one. NVIDIA is a semiconductor company based in Santa Clara, and its products and services include graphics processing units.

A bespoke coldplate for custom designed AI servers: Frore's LiquidJet Diamond. The company claims its new coldplates can handle hotspots with power densities reaching 770 W/cm², reduce GPU temperatures by up to 22C compared with conventional coldplates, and improve AI token throughput (how much work a system gets through in a given time) per watt by as much as 35%. LiquidJet Diamond combines the expertise it used for its original LiquidJet coldplate product and the LiquidJet Nexus bespoke coldplate for Nvidia Blackwell and Nvidia Rubin-based servers.
