Picture of 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.

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?

Really great job! I just wonder what the circuit which can output 12v with the 5v input is. Could you explain how it works?

Hi, the circuit is really simple. The chip I used is MC34063A.

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.
Oh, I see! That makes sense. Great instructable!
