The temperature testing only involved measuring CPU temperatures, but there are other temperature observations to be made. Since there was no provision for measuring the internal temperature of other critical components, the following statements are based solely on my subjective observations. When the test notebook was running with full CPU load, the keyboard, palmrest and bottom surfaces of the notebook felt warm to the touch. They were comfortable to touch, but warm enough to discern a temperature difference from idle. When the Notebook Cooler S was used with full CPU load, these surfaces did not feel any different than from observations made with idle CPU load. From these observations, the Notebook Cooler S was definitely cooling other components of the notebook to a noticeable degree. An important fact is that the test notebook, our Apple Macbook, does not have any ventilation grills/ports/slots on its bottom. I feel that if the Notebook Cooler S did have direct ventilation via the bottom, it would make a bigger difference in regard to cooling internal components, such as the CPU. All notebooks are designed differently in regard to cooling design, so if you have a notebook with ventilation (exhaust or intake) on the bottom, this cooler will be in my opinion, quite effective. Switching the subject, this cooler is only practical to use on flat surfaces such as a desk or table. The reason for this is because only the back of the notebook rests on the cooler, and the front rests on whatever surface you are using. I tried using the cooler with my notebook on my lap, and found it to be unstable whenever I moved. There are other notebook coolers in the market which might be more suitable for this kind of usage, as they provide a base for the whole notebook to sit on. Mind you these coolers are much bigger, they will be what you would look for if you plan on using the notebook on your lap.
Last but not least, noise wise the Notebook Cooler S is fairly quiet. Subjectively, I could hear the blowers when at low or high settings when I was using the notebook. Something to consider however is that most present notebooks use temperature controlled fans which can get exceptionally loud when running at full speeds. If this cooler complements your notebook's cooling system well, your notebook's internal fan speeds would not have to run as fast. This trade-off between the slight noise of the Notebook Cooler S to the high pitch high speed internal fans creates an obvious decision on value.
We found that Antec's Notebook Cooler S is an effective notebook cooler, and when you have a notebook with the right design, it can transform into a very effective notebook cooler. However, there are limitations as to what surfaces you can properly use the cooler on, but otherwise if you are on a flat surface, compatibility is universal. Taking all of our objective and subjective observations into consideration, we are able to say that Antec's Notebook Cooler S provides great value as a notebook cooler, and with the right notebook, it will complement its internal cooling to perform even better.
