Lowers my temperature by more than 10 degrees?!

I received my brand new replacement macbook yesterday and while i waited around 5 days for it, i knit a cover for it, kind of like an envelope that lookslike a sweater for my computer- really cute, it's purple with blue stripes. Anyways, i first downloaded coreduotemp to monitor my temperature and just sitting on my kitchen counter the temperature went up to 102 degrees farenheit. I then shut the lid after going on the internet for a little while. I came back a little while later and put the computer on top of the knit macbook pouch i made. The temperature never went over 93 degrees. Last night i had it on my lap in bed- 107 degrees. I have it on my lap with the knitty underneath- 91 degrees!!!!

Does anyone know why this is, or is the love in every stitch attempting to save my computer from over heating? XD

Temperature can vary widely based on what tasks you are performing (CPU usage) and the air flow around (and especially behind) your MacBook. Also, when you close your lid and open it back up you'll notice that the CPU wait state will have dropped your temperature significantly (even if the MacBook is not "sleeping"). A more valid test would be to verify that your CPU usage over a certain period of time is identical, then measure your temps in different environments...

The lower temp is probably due to the heat being able to move through the knit cover rather than being trapped against a solid surface. However, 107F is not hot at all for a MacBook and well below the normal operating temps. My MacBook runs around 65-70 celsius (up to 158F) and this normal. Under a load it will get up to 80c before the fan kicks on. Don't worry about the heat you are fine.
