He asked the construction department to run a vent to the building’s exterior, with a fan in it.If there’s one thing I’ll guarantee, it’s that a Minnesota winter is as reliable a source of cold as any chiller ever manufactured.For any one reading this whose data center is located in an area where winter is something you can see out your window at least a few months each year: I commend Fitz’s example to you. It’s nearly free, pretty much foolproof, saves electricity, and will make you look smart besides. What’s not to like?– Bob Technology Industry
