Raised Temperatures, Reduced PUE & the Efficiency Gains Hiding in Plain Sight 01/28/2026

Raised Temperatures, Reduced PUE & the Efficiency Gains Hiding in Plain Sight What if the biggest barrier to liquid cooling efficiency isn't the technology itself, but the legacy thinking that's keeping temperatures unnecessarily low? In this episode, Jake Roberts of Excool joins Robert for a refreshingly honest conversation about what it really takes to deliver cooling solutions across global markets, and why the data centre industry's conservative approach might be leaving serious efficiency gains on the table. From retrofitting existing facilities without ripping out infrastructure to challenging assumptions about water use in cooling, Jake brings practical engineering insight to an industry still debating whether to raise chip temperatures above 20 degrees Celsius. Together, they explore: · Why retrofitting for liquid cooling doesn't have to mean reinventing the wheel or running chilled water everywhere · The real efficiency cost of running entire chiller plants at 18 degrees just to handle 20-30% of airside load · How indirect cooling units can decouple airside and liquid cooling temperatures for better PUE · Why NVIDIA's push toward 45 degree facility water loops could eliminate the need for water chillers entirely · The nuanced truth about water use: why a little adiabatic cooling on peak days beats moving the problem to power stations · How West Midlands manufacturing heritage enables rapid, bespoke delivery to global markets · What speed to market really means when customers need solutions in expedited timelines If you've ever wondered whether your cooling design philosophy is leaving stranded power on the table, or wanted someone to explain retrofit options without assuming you're starting from scratch, Jake delivers straight talk with engineering credibility. His insight? Pushing temperatures up has such a positive effect on the industry, from sustainability through to cost efficiency, and the ROI on reduced peak PUE is immediate. /episode/index/show/168a41a8-ad65-4e9b-95e2-0a33ccd2317c/id/39908035
