I believe it is no secret for anyone that the add-on ventilator pads for laptops
that are sold does not make much sense,
to put it mildly. The reason for that is simple.
The turbines that cool the laptops are enclosed systems and additional airflow that the cooling pads provide,
does not create higher air velocity.
In addition, the airflow from them is largely blocked by the lower casing of the laptop itself.
On the small ventilation openings, the air from the pad can enter, hardly can sweep any cooling surface.
Problem:
With the rising power of build in CPU/GPUs in the laptops, the cooling systems can hardly maintain
reasonable temperature even in AC cooled room.
But I have desktop for my room!
The laptop is for the outside. For the bus, for the plane, etc.
In this summer heats the cooling of the laptop cannot behave over 26*C.
And even light tasks like Video on youtube or Age of Empires lead to overheating, thermal throttling
and even inability to touch the laptop because it gets so hot.
My laptop can handle 4K gaming and content creation, but when it overheats, I can not use it.
Analysis:
As Linus once said. The cooling of the laptop is a function of:
Velocity of the airflow. (Higher is better)
Area of effective cooing surface. (Bigger is better)
Temperature of the air (Lower is better)
Temp. of the cooled part (Lower is better)
For the laptops in general we can try to control only one of these criteria –
the area of effective cooing surface.
Idea:
To attach (to solder or to bolt in)
n amount of coper split core electrical cables to the copper tubes of the laptop.
To guide them through the bottom openings of the laptop and spread the inner core of the cable, c
onsistant of smaller copper wires evenly on the outside of the bottom cover of the laptop.
Using this setup with external cooling pad may even work.
I’d like to hear your opinion on that.
May be, even someone will be crazy enough to try it.
