fun title, no? I have a dual 1.8Ghz G5 that's served well for the last few years. It's not overclocked, sports 3GB of RAM, has a decent aftermarket ATI 9800Pro MacSE video card hooked to two Dell 2005fpw screens, wifi, bt, and lots of hard drive space both internal and external. This is, in a nutshell, my primary work machine. It runs constantly, rarely if ever being shut down or restarted for any reason. In my old house, that made no difference, as I was in a large air conditioned room in a moderately small to mid-sized house. Heat wasn't really an issue. I've since built a new house, with a specified office space in it for my business (graphic design). Now you know the basics, here's the issue. This new office is a lot better insulated than my old house, and it tends to trap in the heat being pumped out the back of my G5. I didn't notice so much in the winter, but now the outside temp is picking up, I'm really getting aware of it. The office now stays about 5-10ºF higher than the rest of the house. I've had my A/C company come out and adjust the ductwork to try and port more cold air into that room, and I've got blinds on the windows that stay closed a good bit of the time to try and keep out natural warmth. So... those of you with a Mac Pro and a G5 - can anyone vouch firsthand for the Mac Pro running cooler overall than the G5? If so, is it noticeably (say 10º or more) cooler, or only a few degrees? Anyone else with a similar problem and a suggested way to fix it without replacing the machine? I'm looking down the barrel of replacement soon anyway, but wondered if I can find an easy fix for the short term to get me through the summer without cooking myself and increasing the electric bill just to cool one room.
