The Cooler
The Xcool NP3000 was designed for notebooks with 15" LCD screens. But bigger notebooks will still fit.
Made primarily of ABS plastic, the only large metal part is the aluminium faceplate in the center. That is also where the outlet for the two 70mm fans are found.
The use of ABS plastic is commendable. Because of the extensive use of ABS plastic, the Xcool NP3000 is a really light cooler. It weighs only 650g. This not only ensures a light cooler, it also ensures there is no possibility of burning your thighs with this cooler!
Here is a close-up of that aluminium faceplate and the Xcool logo.
The grill pattern of the two fan outlets is really only there for aesthetic reasons. They do not function as a fan guard as the holes are big enough to allow even adult fingers in. So, do not start up the fans before you place the notebook over the cooler.
On the right end of the cooler's top are two LEDs. Both LEDs have only one function - to light up green when the fans are turned on. Evidently, Jetart retained the two LEDs even when only one would have been enough to ease production across their portable notebook cooler line.
However, I would have preferred Jetart to make better use of the two LEDs. For example, one LED could be lighted up to show the fans at slow speed and both LEDs lighted up to show the fans at high speed.
Like in the Xcool NP5000, the placement of the LEDs was questionable. Once the notebook is placed on the Xcool NP3000, you can't even see the LEDs! So, you will never know whether the fans are running or not.
