As the hot summer came, I began to think more and more about buying a cooling pad for my hot Acer Aspire 5920G ... And now the time has come, I have a stand, for which I decided to write this short review.
Of course, the photo of the stand (from the official site of Zalman):
To see how the laptop will behave with the stand, I decided to conduct a simple test in two modes of the stand:
1. Without the stand,
2. With the stand (coolers at maximum speed).
The test itself is nowhere simpler:
30 minutes of compiling a heavy package (I chose GCC), then 30 minutes of rest.
From all this came a graph showing how cooling affects my laptop:
I can safely say that the stand copes well with its duties, although I expected more! With it, as one would expect, faster cooling occurs.
So, subjective pluses:
And, of course, subjective minuses:

Study Summary
I can safely say that the stand copes well with its duties, although I expected more! With it, as one would expect, faster cooling occurs.
So, subjective pluses:
- CPU temperature now does not rise above 85 degrees Celsius
- GPU temperature stably 6-8 degrees lower than without stand
- pleasant cold helps cool hands a little
- light weight - you can take with you
- very quiet
And, of course, subjective minuses:
- the laptop on top is hot as before
- almost no effect on the temperature of the hard drive
