Does your mac (specifically macbook) get really hot with use??
Mine certainly does... actually to the point of lightly burning my skin if I am using it on my lap wearing shorts etc.
Recently I downloaded smc Fan Control. It is a tiny but great free programme that lets you increase the minimum fan speed to make your mac book run cooler. It works like a charm and within minutes the mac is running cooler and no longer is a danger to me.
Recently I have also added this application to my start up list so that it automatically loads when I start my computer. I am finding that setting the fan control to "higher RPM" is proving beneficial too.
Smc Fan Control now just runs seamlessly in the background and displays a reading of the temp and rpm that the fans are running at.
Sorry macbook... you're not so hot anymore :)
