Its called Macs fan control. Since I was told (by talking to Mac tech support) to eliminate the one app I didn't have anyway to keep track of anything. All seem great in terms of a cool MBP and the fans are so quiet. I actually have to have my MBP brought up to my ear and complete silence to hear anything. I have a feeling that I got all the trouble with my MBP corrected without any professional store help (i.e. The genius bar, the store i go to get things looked at at the spur of the moment, or one of my handful of friends and family who help me when I have a big problem out of the blue. Thank you again, everybody, you are all awesome! PS. I am pretty sure the app is doing a good job because the bottom of my MBP where it actually will rest on my legs isn't very warm at all. I'll keep an eye on it.
