I've had a MacPro since February. For the past month and a half it's become loud with noisy fans. I can be working in Maya or Shake (processor intensive) or watching a DVD only and it's loud. Also the revving often shifts, with periods of greater loudness, without me changing activities. Here are my current temps (it's nosiy now): CPU A - 104 CPU B- 106 Mem Module 1 - 173 Mem Module 2 - 189 Mem Module 3 - 167 Mem Module 4 - 158 Power Supply 1 - 121 Power Supply 2 - 121 I called AppleCare to ask if this is a problem. They're able to handle OS questions, so my questions were a little beyond their domain: they couldn't tell me if these temperatures were bad or if the MacPro is characterized as a noisy computer. They said I should take it in if it shows signs of problems (slowdowns, crashing, etc.) but otherwise it's probably fine. I've had no problems, other than having to turn the speaker up to hear a DVD, no slowdown, etc. I keep going back and forth on deciding to take it in, as it's a day (or half) wasted, I don't have a car right now, and it might be fine (and although I like the Apple Store I find shopping malls monstrous and unbearable). So the question is...Is the MacPro a noisy computer? Is it just the post-winter temperatures running it warmer? If it is noisy, is there anything I can do to make it quiet, besides headphones? Thanks, Happy Memorial Day to everyone.
