Man, the matt in that pic is old-school...lol. Mine just has 2 fans....

I wouldn't mind one fan just as long it was under the cpu cooling vents, but of course it's not, but overall, it still works well. It says it sucks the warm air under the laptop out, and shoots it out the back. Which I can admit because if you put your hands over the fans, you don't feel any air, and all the air, you feel coming out the back.
One reason I got mine was I'm usually laying down while using it, one of the worst things HP claims you can do w/ a "notebook." LOL, I call them about it one day, and they're like "well sir, your laptop is a 'notebook' and you usually use notebooks on desks and other flat surfaces, so that's where your computer is supposed to go..." I'm like, "Hmmm....that's odd....last time I was writing a school report on my spiral notebook while laying down in bed, it didn't start getting warm from me using it too much...''
I just wish laptops had better cooling, like my dad's older laptop had 3 tiny fans in back that did a real good job of keeping it cool w/o it beeing too loud, and I wish that the RAM had better cooling as well... I've thought about custom making my own fan to go under the ram, but unfortunately, I could never find a fan 3mm in width that I needed...lol.
