Macbook pro late 2010 2.53 GHZ core i5 with 8gbs memory installed After doing fairly basic memory intensive tasks computer fans turn on at full speed and memory becomes bogged down http://www.flickr.com/photos/92368436@N05/8395334105/in/photostream After ending most processes, computer fans continue to run at full rpm and do not turn off. Memory seems to lag as well http://www.flickr.com/photos/92368436@N05/8395334191/in/photostream I proceed to shut lid of computer and fans then turn off as computer goes to sleep. when I wake the computer memory bogging is elminated and fans turn off and no lag. http://www.flickr.com/photos/92368436@N05/8395334277/in/photostream The following photos show all processes in Activity monitor. The computer is working fine in this photo for roughly one minute before fans kick on http://www.flickr.com/photos/92368436@N05/8395432011/in/photostream Computer then repeats as before and bogs down. all processes are shown. http://www.flickr.com/photos/92368436@N05/8395432241/in/photostream I have tried resetting SMC, and have used many different programs to clear caches and memory. Computer does not even feel hot to the touch when the fans turn on and after all programs are ended. I have also regulary cleaned computer so no debris is obstructing fans. I have taken the computer to an apple store and they ran testing on memory and graphics cards. They also reinstalled newest OS and updates. At first, I thought this resolved the issue but backing up using time machine caused the same situation. Any Ideas?
