To be blunt, I'm slightly disappointed, and let me explain why. I love the looks of the cooler, and it does do two out of the three things that I require of my testing. It will keep your legs free of the "hot" most notebook users are used to already. It looks super attractive sitting on the desk even when the majority of it is covered by your notebook of choice. The issue here is it fails the most important test for my needs, and that is controlling the temperatures. Now I know I have a thermal nightmare for coolers to have to battle, but one degree of drop in temperatures is almost laughable. The first Antec I looked at was capable of this and the fan concept in that cooler isn't all that great.
I really liked the attention to detail delivered in almost every other aspect of the NotePal U3. Things like the Pass-thru USB connection, and the way the fans clip into place wherever I want them; superb concept! - Visually the NotePal is sleek, and let's be honest, who doesn't like anodized aluminum? For the simplicity of the design the NotePal 3 is sturdy and with the rubber trim things are kept in place right where you put it, and the unit will not slide around. Even on a portability level, the U3 delivers something that will fit comfortably on any lap. But in my opinion, to make the U3 a full on success it is going to take a different fan housed inside of those "trick" clip on housings.
In the end, I have to take this for what it is. At this point I am going to say if it is sold as a notebook cooler, it fails to do that well. Cooler Master does use a bit of wording to shed the U3 under a slightly different light. Labeled as a NotePal, it does achieve the status of being an attractive, simple, and sleek addition to any notebook up to 19" in screen size. It does have a 10° angle to offer and ergonomic experience to your computing and it does elevate the screen, giving you more time at the computer before your neck and back start to feel the pain. With the pricing involved when attaining the NotPal U3, my opinion it relaxes again, and I have to say it is priced very well at the $29.99 seen at Newegg.com. Above all else, it did end up on my desk even though the Antec 200 outperformed it. I simply went for looks and function as the cooler winter months are soon upon us. If you really need some serious thermal help, I would keep looking though.
