Mine is 3.06Ghz so that helps a little. My initial reason for the os upgrade was a clean install but after installing 10.7 onto the second SSD partionof 480GB I found the same stalling issues. After screwing around all night and loading Temperature gauge I started to play with going to energy saving mode to use the less powerful graphics card and lo and behold the stalling was greatly reduces. I googled and found a lot of temperature related stalls. It seem by my limited research the new 1 TB OWC SSD should run cooler than my old 5400 500GB internal drive. I fired up the fans in my cooling pad and then downloaded smc fan controller and even better but still some stall. That was last night today I started fresh and set minimum fan speed to 4K for both fans and again I fired up the fans on the cooling pad I've always used but never activated the fans before. I also used the rear leg risers on the cooling pad and as I type my hands are cooler than ever on the keyboard and wrist area. Also even in high performance mode with the hotter graphics card no stalls while running my pinnicle hd TV stick and iTunes. I run iTunes because I found it would still when the TV stick stalled so it was easier to monitor while edit. So I think my initial concerns of stalling are temp related.
Today I was surprised at how much running firefox taxes the cpu. I open multiple tabs on my startup page and even though only one page is viewable at a time it feels like the passive tabs are also sucking system resources for their flash video etc... I also read others saying how flash and other cpu taxing web video codecs increase the heat load. This all make sense now but I hadn't considered open but background firefox tabs would still be working the cpu enough to cause excessive heat.
As a 2009 model I'm sure I should go back in and blow out more dust than I did when installing the SSD and ram upgrade. There was also mention of replacing/adding more thermal paste but I didn't really dig deep into that thread. Right now just to the touch the laptop is cooler than I've seen it which makes sense with the tile and active cooling pad fans along with smc keeping the fans at minimum 4K. My edit bay is noisy with a portable AC unit anyways so the excess fan noise from the mbp internal fans is not noticable. Think I have the stalling issue surrounded. Now I'll start to play with the new 10.7 partition. For some reason the bootable os 10.8 usb drive I created wouldn't run when I clicked install 10.8 and when I tried to startup with option held to choose the usb drive which shows as EFI something it wouldn't boot and defaulted back to th 10.6.8 partition. I'm wondering if there is a hardware limitation or os limitation that is hindering this install usb I made throught the various sights on how to create a bootable usb os drive. I did the same proceedute for 10.7 and that worked. I wonder if installing 10.7 on the second partition might enable the use of the 10.8 usb drive. That's just a guess or my usb created 10.8 boot up is defective, I've never used it before because my macpro cme with 10.8.3 but I made one for protection sake. I also found out the my carbon copy cloned startup partitions don't have the recovery partition. I think that was an option on later versions of CCC but I must not have checked it and I do have a paid for CCC. I found out when trying to activate "find my iPhone" that it required the recovery partition. I seem to recall using my 10.8 usb then but it was on the macpro. Hmmm so many questions so little time to dick around. I need a software reinstall vacation but I don't see it coming any time soon. And to think my wife like scrap booking when she could be reinstalling my software!!!, and that's not a sex joke.
