Interesting problem here. Lately I will hear the fans spin up to 4 or 5k RPM's every 10 or 15 minutes. They will only spin up then spin back down not staying spun up for an extended period. When this happens while I am on the computer, no performance issues are noted and I don't see anything going crazy in the processes.

In addition, every once in awhile, the system will start lagging badly. The Magic Trackpad and BT Keyboard inputs will get slow and the cursor will be jumping around the screen instead of moving smoothly. Once again, if I open Activity Manager, nothing looks out of place even if I select to see All Processes.

This is on a 2011 15" MBP with the latest version of Lion installed. Any tips on tracking this issue down?
