I never noticed any issues over the past few months although I have been travelling more so I probably wouldn’t have noticed if it was gradual.
I would say for maybe a year it was in my last apartment and I would put the max temp around the 90’s at the highest (accounting for when I was not there).
For the past year it has been in my office and the temps usually do not get past the 80’s (nest thermostat kicks in on the weekends if it gets too hot due to servers in a separate room).
