Hi,
While I agree to a certain extent with what you say, there are also cases,
mine being typical where the laptop is as new, i.e., 100% spotless inside,
the fan and all of its cooling ducts, PCB surfaces etc are totally clean and
free of any dust throughout the laptop. I know this to be true because like
you, I thought that the laptop would be full of dust inside causing the over
heating. Being an engineer I opened the case dismantled everything and
checked for dust etc only to find it was shining like the proverbial
new pin.
It was a new laptop to me, second hand sold as seen and was not working
correctly. So when I found out that dust was not the problem I had to go
looking at other things and found out that the memory had failed. Plugging
in new memory modules the laptop sprung to life but after about 30 Min's of
use I noticed that the cover over the memory compartment was getting hot. I
then googled for information and it seems that laptops are prone to memory
overheating due in part to the fact that unlike desktops or tower units,
they have have to be very compact and as a result cannot shrug off the heat
as easily as air gaps either are so small or none existent.
The size of the fans fitted in a laptop are only a fraction of the size of
those in desktops etc, which usually have at least 2 fans fitted if not
more, to say nothing of the cooling effect of having a large metal cabinet
which acts like a radiator to get rid of heat build up. Laptops are made of
plastic, only have a small single fan and so cannot be as efficent as their
larger counterparts when it comes to cooling.
Laptops are not meant to used to be used for long periods at a time, they
are used as portable computers for business people to use when you cannot
take a desktop etc along to see a client for a presentation, work on the
train or plane etc. Anyone attempting to use one as their main computer for
hours on end regularly will soon experience costly repair bills.
In a similar vein, it is like using a city car as a regular long distance
motorway cruiser rather then a car designed to handle it, the city car like
its driver will all to soon show signs of fatigue and both will require some
TLC.
A cooling plinth costing a few pounds seems like a happy compromise and the
problem must be a widespread one as there are so many types of coolers on
sale in the shops for laptops. It is not the perfect soloution as the heat
has to travel through the plastic casing before the cooling plinth can take
the heat away, but it is better then nothing and seems to work relatively
well.
