Updated on July 2, 2017

Heat Surge

The thing is, heat surge is likely to happen under your laptop or keyboard especially in hot countries which in turn could make our laptop to freeze or shut down.

Good thing lately that the invention of a simple device called Laptop Cooling Fan made our laptops to stay on its performing level even for a long time.

What is a cooling fan?

A cooling fan is a rotating device that has fan blades to push air in a direction towards a heated device to release the heat and maintain its functionality.

The Laptop Cooling Fan is especially designed for laptops or netbooks.

What is a cooling pad?

A cooling pad for a laptop has cooling fan powered by the USB wire of 5 volts.

Cooling pad draws power from the motherboard of your laptop.

There are lots of varieties of cooling pad.

I have taken a photo of my own simple and folding cooling pad at home.

I have the very handy/portable cooling pad with me.

As you can see on the photo, it has four stick to which you can move to minimize space.

The pin-out of the USB is also seen inside the connector.

The four pins inside the connector that will be connected to the laptops USB port are not use at all.

It only uses the two pins, the positive pin and the negative pin of the USB connector.

Turning the folding cooling pad upside down shows the wire and the Y connection to the two cooling fans of the cooling pad.

This simple cooling pad makes my laptop in good condition until today.

It's been four years now since I bought my netbook.

To show how portable my USB powered cooling pad is, I am including one photo folded ready to place inside a handy bag or any laptop case I have for travel.

USB pinout is also shown in the photo.

As you can see, the red wire and the black wire are only the wires that have been used to power the cooling fans. the markings of the cooling pad says DC 5 volts.

I have two cooling fans connected in parallel so it means 5 volts is drawn from each of the cooling fan.

You can also make your own cooling fan at home by just slicing up your USB wires and a connector.

Just look for extra cooling fan of 5 volts in your garage and place it in an hard box or wood enough to place your laptop or netbook.

To conclude, the pins in the USB connector are connected to the red and black wires to the cooling fan to complete the circuit of your cooling pad device.
