Laptops are amazing machines that pack a lot of punch in a small package and as a result, they get very hot. Depending on how much you know about computers, you may or may not know that heat can cause your computer to run in a very unstable way and reduce the life of the many components used to make it run. To combat this in a traditional computer, people can buy heatsinks, water cooling systems, or increase their airflow through the case. However, none of those solutions are very practical on a laptop, so an alternate solution has surfaced. This solution is to place fans underneath the laptop to increase airflow around it. This is in the hope that this increased airflow can move the old, hot air out of the way, for cooler air to come in contact with the chassis and cool the components inside.

The Rosewill RNA-700W Notebook Cooler does just this. With two small fans that are powered by USB under a solid aluminum stand, air flow can be increased to the bottom of the chassis, cooling it the laptop and the components inside. Also, the notebook cooler is tilted at a slight angle which allows for the Rosewill to serve a second purpose, which is to improve the ergonomics of the keyboard. Lets take a closer look at the Rosewill and see how much the temperatures drop.


Closer Look:

The Rosewill Notebook Cooler is one of the most simple coolers I have ever seen. It comes in a cardboard box which lists some of the specifications and features on the front and back. A large picture is also present on the front which gives you an idea of what it looks like, but I had a hard time seeing that it was tilted.



Opening the clamshell style box reveals the Rosewill Cooler sitting right on top. There isn't much to see here except that the fans are in the middle and there is a nice styled Rosewill logo in the middle of the two fans.


Closer Look:

The back of the stand has a small pillar that props up the back of the Rosewill Notebook Cooler and also houses a switch and the place to plug the USB power in. Finally, the cable that came with the cooler has a DC power shaped end on one side and a USB end on the other. It is pretty short, but I would find it hard to imagine it not being able to reach a USB port on any laptop.







The bottom of the Rosewill just has the metal cooler and a plastic housing for the fans. The plastic housing also is how the cooler gets propped up as can be seen in the side view.



Finally, my 15" MacBook Pro is just slightly smaller than the base, with a little less than an inch visible on any given side. Overall, I would consider it a good fit and wouldn't see it having problems even with slightly larger notebooks.


Installation of the Rosewill Notebook Cooler is the same as every other laptop stand ever. Plug in the fan and set the laptop on top. Other than that, there is just a toggle switch that controls the fans being either on or off and can be switched at will depending on what you are doing and how loud you can be. I wish there was more to this part, but honestly, that's all there is to it.

Since the Rosewill Notebook Cooler only has one function that we can measure, that is what will be tested mostly. This function is, of course, its ability to help cool the laptop. The only other function that the Notebook Cooler has is the boost in ergonomic comfort. This is more or less a personal preference that you will have to decide for yourself, however. If you like raised keyboards, then you will love the Rosewill's tilt, but if you prefer flat keyboards, it probably won't be something you will enjoy.

To test the Roswill's cooling ability, I will do what I have done for other laptop coolers in the past. The temperatures will be gathered at idle and at load. To get the idle temperatures, I will make sure I have no running processes on the laptop, then leave it in that state for 15 minutes. After the 15 minutes are up, I will get the temperature and then do the same process on the stand. For the load temperatures, I will run the popular game, World of Warcraft, for 15 minutes in each configuration (on and off the cooler). World of Warcraft will be used because it can stress both the CPU and GPU instead of just testing the CPU like most synthetic Macintosh benchmarks. These temperatures will be recorded and reported in the below segments.

Testing Setup:

Comparison Coolers:


The first results I will look at is the idle temperatures.

As you can see, it didn't perform as well as some of the other coolers, but still showed an improvement in operating temperature. Now for the load temperatures.

In the load temperatures, the Rosewill performed on-par with the other coolers that I am comparing it to. In the case of the load CPU, it even produced the best temperature.


The Rosewill Notebook Cooler did what it said it would do and that is to lower the temperatures of a laptop. While the temperature drop wasn't as high at idle, the Rosewill really shined through in the load temperatures. The ergonomic tilt feature provided a comfortable base for me, but might not be something you would like if you enjoy flat keyboards instead. Another nice thing about the Rosewill is that a non powered USB port can power the fans as they only pull 250mA. Overall, I was pleased with the performance of the Rosewill Notebook Cooler, even though it was lacking a few features that other coolers typically include, like a USB hub or adjustable tilt controls. Features that it did have that are always appreciated, are silence and the ability to go dead silent with the flick of the power switch on the back side of the cooler. Good performance for a reasonable price makes this cooler one to consider when shopping for your next mobile accessory.
