Overview 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, on the occasion of which I decided to write this short review.

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 stand,
2. With stand (coolers at maximum speed).

The test itself is nowhere easier:
30 minutes of compiling a heavy package (I chose GCC), then 30 minutes of rest

From all of this came a graph showing how cooling affects my laptop:

Results of the study

I can safely say that the stand copes well with its responsibilities, although I was counting on more! With it, which was to be expected, there is a faster cooling.

So, the subjective advantages:

• CPU temperature is now above 85 degrees Celsius does not rise
• GPU temperature is stable at 6-8 degrees lower than without a stand
• pleasant cold helps cool hands a little
• light weight - you can take with you
• very quiet

And, of course, subjective minuses:

• laptop on top is also hot as before
• almost does not affect the temperature of the hard drive
