PRODUCT TESTING & USE
As seen properly installed above, the cooler angles the notebooks work surface for an ergonomic working surface much like when you change the position of you keyboard for easier typing. Using a laptop on this cooler is very natural and should lead to a comfortable work environment. Nothing is more awkward than a notebook on a flat desk.
The control and setup of the cooler is painless. Just set the notebook on top of the cooler, plug in the USB cable, press the power button, and turn up the fan. At first I was wondering if the cooler was broken seeing I couldn't hear the fan at all even when using the highest speed setting. Zalman's "Ultra Quiet" claim is completely validated. This cooler is almost dead silent, yet you can feel the airflow coming around the perimeter of the notebook's bottom. Don't expect a huge amount of airflow though, just a steady quiet flow of cooler air.
Cooling performance was pretty good for such a small amount of airflow. Through an infrared temperature probe, without the cooler on the dead center of the bottom measured 33c during load conditions. With the cooler on and set to it maximum airflow, the temperature dropped and stayed consistent at 25.5c - 25.7c. A 7.5c drop in load temperatures is a pretty decent drop.
Now the burning question is, do i buy this cooler, or do I buy another option from another manufacturer. seen above is the size difference between the Zalman ZM-NC1000 and the Antec notebook Cooler S reviewed previouslyHERE. The difference in size will dictate how you use this cooler. The Zalman cooler in my mind is made for a static workstation. Nothing portable, just a place where you place your notebook and work. The Antec Notebook Cooler S represents something that is portable and easy to pack away in a laptop bag for the road, but yet can still be used as a workstation cooler as well. You get my point.
