Notebook Cooling Pad Test
Faced once with the problem of overheating, and as a result of the brakes of the laptop, I decided to test the beech stand with coolers, that is, with cooling.
As a prototype, a cooling pad for a laptop with three coolers was taken. The stand itself is plastic, its upper surface is made of aluminum, it stands on 4 rubberized circles. The stand is also equipped with a built-in USB hub for 4 ports, powered by 5V via a standard miniUSB input. There is a lever "off / on".
Technological specification:
To test the stand, we took an Acer Aspire 4920 laptop with a 1.83 GHz dual-core processor and 2 GB of RAM. Mileage - a year and 4 months. The operating system is Windows Vista.
The principle of the test was as follows: measure the temperature of the main components of a laptop (processor, memory) under various loads without a stand and with a stand. For temperature measurements, the program “Speed fan” was used.
Test program:
Let's start by explaining why the temperature of the computer is so important. And it is important for several reasons. Firstly, if your laptop is very hot, then it is quite problematic to keep it on your knees or flammable surfaces. The tested Acer can easily burn a hole in a regular A4 sheet. Secondly - it is not very comfortable to type on a hot keyboard. And thirdly, and most importantly , increasing the temperature of the conductor leads to an increase in its resistance ( physics, section conductors, paragraph 48 - a consequence of the Joule-Lens law) Plus, in modern processors there is an overheat protection system. To prevent your processor from melting, when the temperature rises sharply, it starts to skip some measures in its work. That is, CONDITIONALLY, if he performs 100 cycles (actions) per second in a normal state, then at high temperature he will do 50 cycles. In simple terms - the higher the temperature of your computer, the lower its performance! In general, the temperature of the computer is a very, very important thing.
Let's start the test. To begin with, we will measure the temperature in a condition of conditional rest.
The screenshot below shows the temperature of the main devices, as well as the load on the processor.
Further, includes Photoshop and Counter-Strike. After 20 minutes, we look at how the temperature has changed:
We see that the temperature has risen strongly, and is not safe for a laptop to work. This is indicated by red lights near the temperature values. In addition, the processor load is 100%, and the game Counter-Strike noticeably "slows down" (and this is on 2 cores and 2 GB of RAM !!!).
Now turn on the stand. It works very quietly, but still a quiet unobtrusive sound from coolers is heard.
We continue to play CS and observe the temperature change.
After a few minutes, the temperature went down, and after 20 minutes it became quite comfortable for work. The keyboard has cooled down, the "brakes" in the game have disappeared.
We turn off games and photoshop and leave the computer to work in a conditional state of rest. We look at the results:
It is easy to notice, comparing with the first screenshot in this article, that the temperature of a computer with a stand is much lower than without it.
Below is a graph of the temperature change of the computer during the entire test period:
On this graph, all phases of the test are very clearly visible: work at rest (indicated on the graph as “ USP” ), work with the programs turned on (indicated on the graph as “CS 1.5 + adobe CS3 "). And the moment when the stand was turned on is very clearly visible.
From this we can conclude that our laptop stand fully and efficiently performs its functions, namely, it cools the computer. In addition, she has a built-in hub for 4 ports, which is also a definite plus. You can easily take her to bed to work on a laptop while lying down or gawk at a movie without straining about the fact that he is unevenly standing and warming your legs very much, and, among other things, she still looks very stylish! A very important nuance - the air intakes at the stand are located on the end and not from the bottom, so the device can be safely used on any surface (blankets, sofas, knees, etc.)
Our verdict is an excellent stand, an excellent product!

Test program:
- Measurement of the temperature of the laptop without open programs and with the stand off (conditional state of rest).
- Measurement of the temperature of the laptop after 20 minutes after an active cut in Counter-Strike (version 1.5) and open Photoshop with the stand off
- Measuring the temperature of the laptop after 20 minutes after an active cut in Counter-Strike (version 1.5) and open Photoshop with the stand turned on.
- Measurement of the temperature of the laptop after 20 minutes after turning off all programs with the stand on (conditional idle state)
- Analysis, conclusions.
