Performance
The Dell laptop that I used for testing usually keeps itself at a moderate temperature, but naturally we are going to push it a little bit here. With laptop coolers I use two applications in 15 minute cycles.  The first test is taking a temperature at full idle after 15 minutes, using SpeedFan to take the temperature.  The second test is maxing out all four cores on the CPU using MaxCPU for 15 minutes and taking a temperature reading.  The third and final test is repeating the test with the laptop cooling fan running.

Before we even discuss the chart above it is important to make one very important note about laptop coolers which I say in every laptop cooler review - your mileage will vary!  They are *highly* dependent on how your laptop is constructed and how the ventilation is designed.  The Dell laptops I tend to work with have more side venting than bottom venting.  Coolers can help, but have limited penetration of the casing.

The difference in temperature was relatively small - only 1.5 degrees Celsius.  I suspect this is due to the LapAir having a relatively small fan when compared to the X-Slim.  This makes it harder for it to penetrate the side venting on the laptop I am testing with.  However, having a cooler did result in a lower overall temperature during extreme use.  During normal usage when you only have spikes in temperature periodically, this will help remove the excess heat buildup quicker.
