Intel is testing a new way to tackle the growing heat output of its power hungry chips. At its recent Foundry Direct Connect event, the company showcased an experimental package-level water cooling solution designed to more efficiently cool CPUs . Intel has working prototypes for both LGA (Land Grid Array) and BGA (Ball Grid Array) CPUs, with demos using Intel’s Core Ultra as well as Xeon server processors.
The cooling solution doesn’t apply coolant directly to the silicon die. Instead, a specially designed compact cooling block sits atop the package, featuring microchannels made of copper that precisely guide the coolant flow. These channels can be optimized to target specific hotspots on the die, potentially improving heat removal where it matters the most.
