Overview of the cooling pad for laptop ZALMAN ZM-NC1500

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.

Bit of theory

Cooling pad

The number of coolers	2
Cooling	1100 - 1500 rpm. ± 10%

Of course, the photo of the stand (from the official site of Zalman):

Study

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:

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
