No, I'm not Bill Gates and I'm not Steve Jobs too! But I'm not doing a wild statement. Despite the facts that lots of vendors selling expensive and 'advanced' cooler pad, it didn't keep your laptop as cool as you thought. Most will only give you 1-3°C difference when equipped.

Cooling method that use fan to enhance the cooling effect. The fan either powered by USB connection to the laptop or using batteries. Most common cooler pad can be found on the market.

Cool air from surround is sucked by the fans inside the cooler pad and then blows toward the air intake below your laptop. This action should improves the flow of cool air into the laptop to enhance the cooling. The cool air will decrease the temperature of your main components such as hard disk, processor, and graphic processor. The hot air will be pushed through the vent at the side of your laptop.

There are hundreds of computer company in the world, thus producing thousands of different model of laptop. Different models having different design, and that's what make most cooler failed to do it's work. Check out these laptop's vents:

Looking at the difference in the placement of the vents of those models, we can clearly see why most cooler pad can't work efficiently. These weakness bottleneck the cooling potential of the cooler pad tightly and make all the money you spend for a decent cooler pad seems useless. Apart from that, actually at the bottom of most laptops only consist of one intake vent, and other vents are for HDD and RAM, which exhausting hot air, not sucking cool air; something that most failed to realize.

There are companies that realize this problem and came out with new cooling technique. They start to use larger fan instead of multiple small fans so that no matter where your vents are placed, the air pushed from the fan can go into the vent. However, larger fan are slower. Slower fan = less air = less cool.

Some companies even came out with the idea of sucking hot air from the exhaust rather than pushing cool air into the laptop. This method sounds good but the reality shows otherwise. In cooling your laptop, what's matter is to make sure fresh, cool air flows through the hot components. However, this method still can help to improves the cooling effects if you already have decent cool air flows through the bottom of your laptop.

Few months ago, Cooler Master announced their new product. This is an awesome product with brilliant idea that worth to be praised. Cooler Master NotePal U3 is a unique cooler pad that have 3 fans that can change position easily so that you can placed it to right below your vents for efficient cooling. NotePal U3 may reduce your laptop temperature by 5°C given an optimal condition. Apart from that, it can be used as a laptop carrier and to improves the viewing angle of your laptop. However, due to some weakness, this cooler pad cooling potential still not good enough. Click here for more images.

When you go to computer shops, you may find that there are some coolers that having fans that sucks air rather than blowing cool air. A few companies thought the bottom part of the laptop is solely for exhausting air, thus they design cooler pads that sucks all air from the vents, which is dangerous because that will prohibit any air from moving through the intake vents and may cause overheating. Using poorly designed cooler pad is dangerous after all.

The bottom of your laptop consist of exhaust vents. By absorbing the heat exhausted from the vents using suitable materials such as aluminium and distribute it evenly across all dissipation area, heat accumulation at the bottom of laptop can be prevented thus reduce the temperature of laptop.

Differ from what most people believes, the bottom of laptop consist both intake and exhaust vents. Therefore, the laptop will need fresh, cool air from outside to moves through the intake vents.
