140 is nice 'n' low. That's 60 deg C, which is well within the acceptable range of modern processors and their coworkers. It's when you're getting up to 70 or 80 that you should worry.

Now, I like my processors running around 50, but I also have the luxury of not running them in a 1/2 inch thick case.

I am the Doctor, and THIS... is my SPOON!
