AI is an enormous energy drain, contributing to greenhouse gas emissions at a time when the planet desperately needs progress in the opposite direction. Although most of that comes from running GPUs, cooling them is another significant overhead. So, it's worth noting when a company of Microsoft's stature claims to have achieved a breakthrough in chip cooling.
Microsoft's new system is based on microfluidics, a method long pursued but hard to implement. The company claims its approach could lead to three times better cooling than current methods.
Many data centers rely on cold plates to prevent GPUs from overheating. Although effective to a degree, the plates are separated from the heat source by several layers of material, which limits their performance. "If you're still relying heavily on traditional cold plate technology [in five years], you're stuck," Microsoft program manager Sashi Majety is quoted as saying in the company's announcement.
