Have you checked using 'Activity Monitor' (in Applications -> Utilities folder)?

Check under CPU tab and find the process 'Lightroom' and it's corresponding CPU usage.

On my system, the process is pretty much idle either in Develop or Library modes - if it's CPU usage is near 0, it can't be the cause of the heat as it isn't doing anything...

Thanks for the tip. When LR is active the activity monitor is showing drastic changes in CPU usage in both library and develop module. Ranging from 20% to 120% range.
