Yeah, below 65 degrees. My preference is around 70 or 75. I only start to overheat when it gets above like 105 like when it did on Fourth of July this past year. Granted in computer labs and stuff it's easy to layer up but that doesn't help much. The previous office I worked in kept it about 52 and I was dyingggg. The difference between that office and this one I'm in now is that we aren't allowed to bring in heaters or layer up or anything because it's not business appropriate.
