What is the Iceotope KUL AI?
KUL AI is a server rather than a piece of facility equipment. Iceotope builds it around a Gigabyte G293 board carrying two Intel Xeon Scalable processors and up to eight graphics processors. The chassis is sealed and filled with dielectric fluid, so the fluid reaches every heat-generating component instead of only the processor lid. Iceotope calls this precision liquid cooling and says it removes the need for supplementary air cooling. The company reports up to 40 percent lower server energy use and up to four times the compaction of an air-cooled equivalent. Those are company figures against an unnamed baseline, so they describe a direction rather than a guaranteed result for a given hall. The board is served by two 3 kW power supplies, and the storage and expansion bays sit outside the fluid volume. Iceotope also published a laboratory result in which the same architecture cooled a 1,500 W thermal test vehicle at 8 liters per minute; a test vehicle is not a shipping processor. Public material does not state facility-water temperature limits, flow per chassis, pressure drop, fluid volume, or the service interval for the fluid. A buyer should ask for the rated inlet water temperature, the flow the chassis needs at that temperature, who warrants the server once it is filled, and how a failed board is drained and replaced in a live rack.
