Just a quick question on the "safety" of my current daily use routine. I get to my research lab at ~9am and open my 15" i7 MBP (Mid 2010 with the 2.8GHz processor and 8GB of RAM). I plug in my display port adapter to my 24" monitor. I run Safari, Microsoft Word, Excel, and PowerPoint, Parallels 7 running Win 7 HP and the 3D modeling software Solidworks (Parallels on the external monitor), and iTunes. I use an external Mouse and a "SpaceBall" for 3D modeling. I remain plugged into the wall, and use an Ethernet cable with the WiFi turned off. My 3D models are composed of ~120part assemblies, so they are fairly large. I'll work all day, until around 3 or 4pm. Shut down most programs, except Safari, and close the lid. I rarely do full reboots. My temps in my daily use, according to iStat Nano on the Dashboard, have CPUA hovering right around 175˚F. In "normal" use, they seem to be right around 145˚F. That's the highest temp, but all the others are elevated over normal levels. Is that "unsafely" hot? Is there anything I can do to improve cooling (I do have an iSkinz keyboard cover, though I was told the keyboard has nothing to do with cooling as it does on some other computers)? Or are those temps perfectly fine and nothing to worry about? I recently, about 9 months ago, switched from the stock 500GB 5400RPM hard drive to a 500GB Momentus XT hard drive (7200RPM, with the SSD portion, you all know the one). I've been contemplating the jump to the new 750GB Momentus XT drive, as I am approaching "full" on my current hard drive (only ~80GB remaining). Any help would be great! Thanks!
