Frore unveils diamond-infused coldplates for 2,300W Nvidia Rubin, claims up to 22C drop
Frore Systems introduced LiquidJet Diamond, a bespoke liquid-cooling coldplate series that adds diamond-wafer heat spreaders at the bottom of the coldplate to target hotspots on next-generation AI accelerators such as Nvidia's Rubin and AMD's Instinct MI400 and MI500. The company claims the design handles hotspot power densities up to 770 W/cm², lowers GPU temperatures by 16–22C versus conventional coldplates and improves AI token throughput per watt by 30%–35%, though those figures come from its own models and it has not disclosed how the diamond wafers are manufactured or integrated. Frore plans to demonstrate the technology at the OCP Global Summit on October 12–16, showing cooling for Nvidia's 2,300W Rubin, but has not said whether the demo uses production GPUs or a thermal test vehicle.
As accelerators like Rubin push toward 2,300W, hotspot cooling is becoming a bottleneck for AI compute deployments.
