Huge disclaimer that I'm not an expert on this, but: Googling suggests that you're trading off electricity used to cool the data center with electricity used to blow the air over the electronics, and that ~25C is the temperature where the sum of those is minimized: https://i.dell.com/sites/content/business/solutions/whitepapers/en/Documents/dci-Data-Center-Operating-Temperature-Dell-Recommendation.pdf https://i.dell.com/sites/content/business/solutions/whitepap... On Oxide and Friends (a podcast by a startup building servers) they claims their choice to use larger quieter fans reduces the power consumption of the fans from ~20-30% of the power a rack consumes to ~2%. Which might suggest that that ~25C number is actually a result of poor hardware choices for moving air more than anything else. https://youtu.be/xNLxknaj72g?si=TWdQnHIRq_BsOOXi&t=3301 https://youtu.be/xNLxknaj72g?si=TWdQnHIRq_BsOOXi&t=3301
