DIY: Laptop Cooling Pads
| by Francis D'sa
With gradually dropping laptop prices, most people prefer to have one at home or in the office simply because it offers the convenience of a compact computer. High-end laptops are quickly becoming desktop replacements and are in great demand for resource-intensive uses such as graphics design, video rendering, and even gaming. With prolonged and extensive use, a laptop tends to heat up faster and higher than the normal working temperature. A laptop used on a regular table has some drawbacks; the limited gap between the laptop base and the table doesn’t allow adequate airflow and, at times, creates a bad ergonomic posture for keyboard use. We show you how to make a simple and efficient laptop cooler in just under
Note: We have made numerous holes on the fan area for sufficient airflow. You can also cut a 120 mm hole and add a protective mesh or a fabric as a dust filter for additional airflow. When the drilling is complete, you will need to smoothen the entire surface to get rid of sharp edges formed due to the drilling. Use sandpaper or a metal file to smoothen the sharp edges and then polish the entire surface of the sheet for a final paint job (if required).
The next step is to bend the sheet. The bending process is a tough one, but made simpler
Note: The engraving needs to be done on the opposite side of the bend. Click for larger view
While the cooling pad is drying, you can get the fan circuit ready. Solder the fans, potentiometer and the DC power jack in series according to the circuit diagram shown on the left. You can use 5 V DC brushless fans and have them powered using the laptop’s USB port, but as 5 V fans are difficult to procure, we have used two 12 V fans rescued from an old PC case. You can eliminate the potentiometer if you do not want to regulate the speed. Speed regulation is only beneficial to cut down the whirring sound when high speed fans are used. You can also add a switch if you need one. Additionally, you can also personalize the cooling pad by including a USB hub, speakers, lights or anything else that comes to mind.
