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.
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
This is the aluminum shell I choose. It is 8*9*3cm. What’s more I love the color very much.
This is the centrifugal fan I use. Its working voltage is 12v and the current is 0.2A.
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.
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.
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.
Then I put the centrifugal fan and step-up power circuit into the shell and assemble the front and back plates. Like this.
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.
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.
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.
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.)
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)
This picture shows the temp of my laptop without my cooling device after the 15min test.
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.
