Ok, first a disclaimer - on one of the posts here, I claimed my 2.7 CPU (new MBP) got around to 70 degrees while running CPU intensive tasks. It seems I was wrong, I didn't look at the correct temperature in iStat Menus, I was checking CPU Proximity - and it's true, I just can't get CPU proximity over 70, in fact, it's around 60 for even the most intensive tasks. However, I didn't observe CPU Digital Core and Die (PECI) sensors. No idea what those are. But these hit 90-100 degrees on a regular basis when running Zbrush. Continuous brush strokes cause these to constatnly go from 95-100, and pausing for even a very short time drops them down. But if I keep working, they are near 100 all the time. Now, I didn't measure temperatures with iStat Menus on my previous MBP, but it was definitely more warm to the touch than the current model, and the fans were blowing full force. My current MBP is not very warm to the touch and the CPU proximity is rarely above 60, never hits 70. But, as I said, Digital Core and Die are a different thing. This never happens while I'm using Photoshop and Clip Studio Paint, but these are not CPU intensive. So, my question is - is this normal? I didn't worry about this for almost three years with my old MBP, and it felt warmer to the touch than the new one. But for some reason I started paying attention, and now I've brought myself to full paranoia mode: is this normal? Is it safe to run Zbrush for hours and hours? Anyone has any info? Thanks.
