Not here. With ~3.5-4kW worth of computers running 24x7, we run A/C
year-round. With how hot our part of Florida has become over the past
5-6 years, we'd probably still be running A/C year-round even without
the computers. It's unbelievable. That's the big reason we're trying
so hard to move back up north.
