How to Make a High Efficient Ventilation Cooling System for Laptop




In summer, how to cool my laptop is always a big problem for me. My laptop is Y460 which has core i3 and HD 5650, so it is really hot when I am playing games on my computer. I have bought a laptop cooling pad, but I found it useless. The cooling pad can only decrease the temp of the CPU and GPU 3 to 5F, and I can’t satisfy with such bad effect. And I want to create a new way to make my laptop cooler.
The above picture shows what I made.

Step 1:

Though I only use this device myself, but I still like to keep the device as dedicate as possible.
In order to finish making this device, we need a aluminum shell, a centrifugal fan, a step-up power module and a self-locking button. And I find a great website to help me make this device. You can check this website here.

Step 2:

This is the aluminum shell I choose. It is 8*9*3cm. What’s more I love the color very much.

Step 3:

This is the centrifugal fan I use. Its working voltage is 12v and the current is 0.2A.

Step 4:

Before making the pcb, I use the universal circuit board to test the circuit which can output 12v with the 5v input. The test circuit is showed above.

Step 5:

Then I draw the single layer pcb to make the circuit so small that I can put the circuit and centrifugal fan together into the shell.

Step 6:

Is it small enough?
After I got all the parts I listed before, I start to assembling the my device.
First of all, I need to put the self-locking button into the shell which has already been drilled by UFactory. Unfortunately I made a mistake in the size of button so I need to use the drill driver to make the hole bigger first.

Step 7:

Then I put the centrifugal fan and step-up power circuit into the shell and assemble the front and back plates. Like this.

Step 8:

Originally, I think I have already finished the assembling, but when I saw the big air inlet I realized that I need to find something to cover the air inlet. And I find the screen - a kind of net. Do you think it looks much more better? At least I think.

Step 9:

Before I make use of the device, I also need to use some soft material like EVA to make the device and computer fit closely.

Step 10:

After finishing doing that, you can see the finial device beside my laptop. And it really works well. Let’s see the temperature test I have made.
I use the the System Stability Test from AIDA64 Extreme Edition.

Step 11:

Before starting the test, I should know the temp of my room, so I take out the device to measure the temp. It is 32℃.(Does this device looks lovely? I like it very much.)

Step 12:

This picture shows the normal temperature(℃) of my laptop.(the blue line is the temp of CPU and the yellow line is the temp of GPU)

Step 13:

This picture shows the temp of my laptop without my cooling device after the 15min test.

Step 14:

And this shows the temp of my laptop with my cooling device also after the 15min test.
Generally speaking, both CPU and GPU’s temp are more than 10℃ off. To tell you the truth, I am very satisfied with my cooling device.

That's a great design ..two questions: what are the fan specs for power and airflow? and would it be possible to adapt your design to use the laptop usb port to power the your device?

Awesome design! Love how your desperation to make your device look nice! Where did you get that temperature measure device? it looks really sick!

I don't know what do you mean by looks really sick?
I made that temperature measure device by myself.

That looks great, but where is the circular hole you would need for the fan's air supply and internal cooling? I don't think I saw it? I think with a hole there and facing up, you would get even cooler and higher velocity air

Hi, I didn't get you. You mean drilling a hole on the top of the device? If you mean this, I think the efficiency will be lower. Because the air supply are not only from the laptop's inside hot air but also the cold air outside.

The fan you pictured is a centrifugal fan, so it pulls air in at its axis, which requires a hole a little smaller than the diameter of the fan. Then the output lease the chute designed in the fan. Rarer than cooling the hot air, it would be more efficient to pull in cool air and displace the hot air with the cool air.

Yes I can understand. It will make the device more efficient. But if I drill a hole at its axis, the device will be more higher. And the whole device will be less portable.

Awesome!!! I really want to make one for my laptop. It seems that this device works very well!!!!
