Basically, got a used MacBook Pro, and it's overheating when I use almost any software at all. It was overheating a bit at idle, and I got smcFancontrol, which fixed most of the problems. Thing is, when I use any intensive program at all, specifically games or PhotoShop/Illustrator, temp spikes and it goes all flickery and overheats, eventually causing me to force shutdown. Afterward, it has to completely cool to avoid the endless gray screen of restart circle. Specs: 2007 MBP Mt. Lion 10.8.5 2.4 GHz 4 GB RAM GeForce 8600 GT Idle without the fan control runs about 60-65C With fan control (ramped to 5K-5.5K RPM) it'll run solid around 40-45C. When apps are launched (tried WoW, DDO, and The Sims 3 since I had access, though oddly, no problem with Torchlight or some virtual box apps) it'll run 65+C and hotter, even with the fans ramped to 6k rpm. I have istat, and I'll post what's going on when I get it fired up (no pun intended). Posting this from my phone right now. Edit: There's also some lag going on in the hard drive. It takes forever to write, and it's slow on startup. Couple minutes to fully launch. I'm planning on replacing the HD regardless. I was wondering if that may have something to do with the heat, if something was wrong with it (it makes the grinding noise when it starts. My old regular MB did that after having some HD damage, FWIW) Thanks party people.
