Frore claims its diamond-based cooling systems lower junction temperatures by 22 degrees Celsius on Nvidia Rubin chips drawing 2,300 watts, according to BigGo Finance.

The figure matters because it targets the exact thermal envelope now defining AI datacenter design. Rubin-class accelerators at 2,300W exceed what conventional air cooling and many liquid loops can absorb at acceptable operating temperatures.

What does diamond change?

Diamond conducts heat several times better than copper, the standard material in cold plates and heat spreaders. Placing a diamond layer between a chip's package and the cooler moves heat away from the die faster, reducing the temperature gap between the silicon and the coolant.

A 22C drop at a fixed 2,300W load buys operators one of two things: higher sustained clock speeds on existing silicon, or cooler-running hardware with longer service life and lower thermal stress on surrounding components.

Why 2,300W is the benchmark

Frore's claim names Nvidia's Rubin generation explicitly. Each new accelerator generation has raised thermal design power, and cooling capacity — not transistor count — increasingly limits how densely racks can be built.

If the 22C figure holds in deployment, diamond-based coolers could allow:

• Higher rack densities without exceeding thermal limits
• Reduced coolant flow requirements for a given heat load
• Sustained boost clocks on 2,300W-class GPUs

Frore has not yet published third-party validation data, so the 22C figure remains a vendor claim. BigGo Finance reported the numbers; independent benchmarks have not confirmed them.

Market impact

Nvidia's Rubin roadmap anchors the upgrade cycles of the largest hyperscalers, and every vendor in the thermal chain — from cold-plate makers to coolant suppliers — aligns its product claims to that roadmap. A cooler that delivers a 22C reduction at 2,300W would reset expectations for the entire segment.

Until Frore ships production units or publishes measured results, the claim stands as a specification target, not a verified result. Diamond cooling for Rubin-class chips is now on the industry's radar at 22C and 2,300W.
