So, I bought this case about 1 year ago. And if you don't know the specs, it has 3 120mm fan ports, 2 intake, 1 exhaust.
Anyways, When I bought the case with my build and upgraded the CPU to a Q9550 and the fan to an Ultra X Wind the temps were idle around 32-34c.
Well, just yesterday I moved into my new place and the temps in the house are about 5-10 degrees cooler than my old house. So just being curious I checked my temps on my 9550 and they were 21c sometimes 19 at idle. I was just amazed by how much room temperature affects the computer temps. Also, The Apollo case is amazing imo. For $70 total you get something well worth it and better than all the others in the same price range.
Edit: Just to put it out there, my GPU temps also went from 60c idle to 48c.
