How to choose notebook cooler?

Notebook cooling base will play a positive role in the stable operation of notebooks, especially when you use books to play games. If you really care about your notebook, you can give a laptop cooling base. However, the problem is that the quality of cooling bases in the current market is uneven and there are certain differences in specific positioning. It is indeed not easy to choose a product with good cooling effect, quiet operation, convenient carrying, and affordable price. So, notebook cooler which is good, what should pay attention to specific issues when buying it?

1, buy radiators pay attention to problems do not blindly pursue low prices in the market, we can often see some very low price of "cottage brand" cooling base, in the dealer's "highly recommended", many consumers will be unable to ban low price The temptation to buy them. However, it will take some time to find that they use thin steel or inferior plastics, which cannot improve the heat dissipation effect, and the fan noise is unbearable. Some products even have potential safety hazards. In the end, most users can only choose to throw it away.

2, metal material priority The current common heat sink base material includes three kinds: aluminum alloy, iron/steel and plastic. Although the plastic material is cheap, but the thermal conductivity is poor, and the location of contact with books is prone to heat accumulation; iron / steel material cooling effect is good, but the weight is relatively heavy, handling or carrying will be very laborious; Relatively speaking, aluminum alloy The material has the advantages of good heat dissipation and lightweight and portable, so it is worth giving priority.

3. The larger the size of the cooling fan, the better. For those bases that actively dissipate heat through the fan, the air volume directly determines the cooling effect. Air volume = fan size × fan speed. The higher the fan speed, the greater the noise. Therefore, the best state is to keep the speed at a lower value (preferably not more than 2000 rpm) and increase the size of the fan as much as possible. Better than 7cm).

4, can not ignore the hidden dangers When we observe the bottom part of the cooling base, you will see no protection measures on the back of the fan, if the user's fingers accidentally touched, the consequences will be disastrous, so we should first select those fans were Baffle spaced cooling base. In addition, the corner position of the base should also be folded or curved to avoid scratching the user's fingers.
