I have a 14 inch Asus K450ld. I need a laptop cooling pad that is fairly comfortable to use on the lap (yeah yeah you aren't supposed to use it on your lap. I don't have any other options) but of decent quality and that has fan placement in the right spots. My usage isn't heavy (I don't game for 12 hours a day) so the air flow doesn't have to be extreme. Just pretty good. I have a Targus Lap Chill Mat but found it to be too weak. I'm currently just using it as a stand because the USB cord broke off.
Below is a picture of the bottom my laptop so you can see where the air vents are.
