( This looks long, but its easy, I promise! I just tried to make it detailed! ) Hello, we have ordered 3 of these around the same time and all three exhibit this same issue. I was wondering if anyone here could test this for me and see if you have the same problem as well. To test it, you will need something to monitor fan speed and temperature. A very easy option is the iStat Pro widget, available here: http://www.apple.com/downloads/dashboard/status/istatpro.html It should show, on the right, fan speeds and temps. We are only really concerned here with the CPU A temperature (celcius, please). Now you just need to get CPU load up for a minute or two somehow. One easy way that works for me is to run iMovie HD, do the Magic Movie thing and just accept all the defaults. It should open up a camera view with yourself visible and searching for a DV camera. If you go to the dashboard and check iStat, your CPU use should be at least 50% (less than 50% idle) hopefully. Watch your CPU A temperature. If it gets towards 60c, the fans should speed up (faster than 2000 RPM). Can you guys just let me know if your fans ever exceed 2000 RPM? This has to be a new model, by the way.. Santa Rosa chipset, nVidia 8600, etc. Please post whether your fans speed up or not and if you have BootCamp installed. Thanks for any help.
