Cooler Master NotePal Ultra Slim R9 NBC XSLI GP
I have what my husband calls a "giant" laptop- it has a 17" or 19" screen or something (I can't ever remember which), and it's difficult to find a cooler that will fit under the whole computer. This one works perfectly- it fits completely under my laptop. I really like the option of having "feet," even though I don't always use them. I also like that I can plug the USB in either side- really convenient. I have my computer on it all the time, and just plug in the fan when I'm going to be using it for long periods, like writing a paper or something. Even without the fans on, my computer stays much cooler.
Overall, when this cooler dies, I'd buy another. Seems well-made and reliable, and like it will last a while if you take care of it. I am definitely happy with this one!
