Testing & Results

Testing Methodology

To test the effectiveness of the cooling pad a System Stability Test was conducted using AIDA64 Extreme Edition. This test stresses the CPUs, FPU, cache, and system memory, which should result in a maximum heat situation, or at least provide an opportunity to measure the effectiveness of the cooling pad. CPU temperatures were used as the test data, and monitored using the AIDA64 Computer/Sensor sub-menu.

Room temperature was monitored to ensure that the test conditions did not affect the results. The notebooks were turned on and allowed to sit idle (CPU use less than 5%) for approximately 15 minutes, on a hard surface to establish a baseline temperature of the CPUs. The notebooks were then placed on the cooling pad and allowed to idle for another 15 minutes to provide a data point at idle, to identify if there was any effect from the cooling pad at idle and at maximum cooling fan speed. The laptop was replaced on the hard surface and the AIDA64 System Stability test started.

After at least 15 minutes, when the laptop temperatures were stabilized and they were recorded. The System Stability Test was then terminated and the laptop allowed to return to idle temperature. Then the laptop was placed on the cooling pad, with maximum fan speed, the stability test restarted and the temperatures allowed to stabilize, and then recorded.

In this manner data was collected from the two test laptops.

Above is the test set up for the DeepCool M3 Cooling Pad. As you can see care must be taken with the interconnecting USB and Sound Cables to minimize entanglement when moving the two as a single unit.

Results

The results are summarized in the following table:

M3_Cooling_Test_Chart.jpg

As can be seen there is a measurable cooling effect that the DeepCool M3 Cooling Pad has on the laptop computer. 1.5 to 2 degrees Celsius seems to be usual. It must also be noted that when I used a stand-off temperature probe I found that the highest temperatures on the laptop were off to the side, which says to me that the CPUs where most likely not centered above the center mounted fan. In addition, the HP Pavilion has an opening in the bottom center whereas the Toshiba Satellite did not. This could also contribute to the differences in the cooling effect of the cooling pad.

Heat transfer between the laptop and the bottom surface of the cooling pad was minimal, and so as a method of reducing direct heat transfer the cooling pad was very effective.

The built in speakers are the other main feature of the DeepCool M3 Cooling Pad. I was able to use the sound output from the laptop to test the output from the cooling pad. The testing method used was to play different types of music and to increase the volume until distortion was apparent, and then reduce the volume until the distortion disappeared. There was a tendency for the speakers to distort when the volume was approximately 65 % of the maximum. The DeepCool M3 adds amplification, however there is no on board volume control so the sound is louder than when played through the laptop. The sound was also fuller sound and the bass clearly had better resonance. In summary, the DeepCool M3 cooling pad may not blow the doors out of the room, but it makes a good listening environment to work in.

Does DeepCool have any plans on making a version for 17.3" laptops..?!

DeepCool has a N9 Aluminum laptop cooler that supports up to 17", I would think that it would hold the 17.3" model too.

These laptop or notebook that have vents on its base
because it prevents these vents from being blocked regardless
of what ever surface the laptop is used on.
desk,lap notebook
uneven/soft surfaces and outdoors.

You are correct. Laptop cooling pads provide a surface for laptops to rest on so air will circulate through the laptop when the cooling pad is placed on a soft surface such as a blanket. They also allow your hands a more natural approach because the laptop does not sink into the soft surface either.
