Hi guys, I have a 3 week old Quad 2.9 mac pro with ATI 4870. I have noticed the temp to get around 75C+ while CPU is 99-100% idle. I've noticed mostly when running itunes the temp will just keep climbing...fast! Within 3 min of running itunes my computer is at 65C (attached). When running Photoshop/Dreamweaver/Lightroom, the temp doesn't get as high. I've installed SMC Fan Control, and it helps, but the temp will still climb, just slower. Do the new Mac Pro's run hot? Any ideas? Thanks!
