Hi, The conventional laptop design has 3 vents. One is usually on a side or back face and vents the power supply. The other two are usually on the bottom and are intended to disipate the heat from the processor and hard drive. The problem with these is that they usually aren't fanned. Therefore, if you use a conventional laptop on your lap the heat from the processor will be dumped right onto your thighs. It's very disconcerting especially if you dwell on it.
Apple's design has one fan at the rear which does for the whole laptop. They get away with this by using aluminum materials so that the entire laptop dissipates heat. For normal use, your laptop should feel like it's running at room temperature. Even if you fire up your windows virtual machine, the heat should be tolerable unless you try to do something really high end under windows. Fan noise all the time and constant heat speaks to me of something inside your laptop. You don't for example, have a guide dog by chance? Dogs shed, and no matter what a good dog owner does, they will invariably be covered in dog hair. It sticks to clothes, fernaturem bedding (even if you don't allow your dog on the bed)... No matter how well you keep things up, dog hair can get into your laptop. That happened to a client of mine who refuses to use a desk, storing her laptop on the floor and using it laying down on the bed. And of course, dog hair from clothes, bedding, and especially floor was pouring into her laptop all unbeknownsed to her. I believe in laptop coolers myself because of my experiences with turion notebooks, but you shouldn't necessarily need one for your mac.
