How to choose a CPU cooler?
The hot weather not only makes people feel boring, but even the computer is so hot that it doesn’t move. What should I do? Friends who have some basic computer knowledge know that the CPU is equivalent to the heart of a complete computer and plays an extremely critical role in the performance of the system. However, the CPU is also a large heat component in the computer hardware. If the heat dissipation is not good, it will easily cause the computer to crash or crash. Uninterrupted restarting and other issues, at this time, you may use the u disk to install the system, it may not help. So how to choose a CPU cooler is very important.
Why does the computer get hot? Where is the fever?
Dissipating heat, where is the heat dissipating? The processor and the graphics card are the big heads of the computer's heat, and they are also the focus of the temperature monitoring of the various housekeeper software. The reason why the computer can run depends on the processor. He has been running, so he sweats and heats up. Occasionally, if you drive a large-scale use, it is like encountering a big slope, and it takes more effort to run up, and it will sweat more and get hotter. In addition to the graphics card and the processor, the hard disk also gets hot. If your computer is relatively old, you will hear the sound of the hard disk spinning. In this case, I suggest you change the hard drive~
Why do we need to cool the computer?
High temperature will reduce the hardware operating speed, reduce the hardware life, and in severe cases will burn the hardware. It's like 40 degrees in summer, if you go out and run 10KM, you will think this is murder. If you have been to Master Lu, you have turned on the temperature alarm. Therefore, every computer will have a cooling fan. How to choose a CPU cooler
1. Generally speaking, 30% of the heat dissipation effect of the radiator depends on the speed of the fan, but the higher the speed of the fan, the better. The increase in the fan speed does increase the air intake and improve the heat dissipation effect; but the higher the speed, the greater the noise, which will greatly shorten the life of the fan, and the greater the power supply pressure on the motherboard and power supply. Even cause system instability. The correct fan speed should be determined based on the heat generated by the processor.
2. Don’t be overly superstitious about copper fans. It’s not good if they aren’t copper fans. Some fans of other brands have exaggerated styles and sensationalism. When choosing a copper fan, you should pay attention to its anti-rust process, because inferior copper fan has poor anti-rust ability, once copper rust is applied, its heat dissipation performance will be greatly reduced.
3. There are some things to pay attention to when choosing a side-blowing fan, because the measured ambient temperature differs by as much as 5 degrees because of the direction of the side-blowing fan fixed on the chassis. So everyone must pay attention to the heat flow in the chassis when using side-blowing fans. In addition, there are copper-inlaid fans and double-sided blowing fans on the market. Due to their craftsmanship and other reasons, their heat dissipation efficiency and performance are not ideal.
4. If you pay more attention to the noise of the fan, you should choose a ball fan when choosing, not an oily fan. (Ordinary ball fans, just blow it lightly with your mouth, they will spin) Nowadays, good brand fans are generally ball fans.
In addition, you need to pay attention to the following two points when choosing:
1. Use with the host
Generally, the larger the heat sink of the cooling fan, the better the heat dissipation effect, but the position of the fan in the host and the size of the space in the case must be considered. You should also pay attention to whether the host can accommodate the height after the fan is installed, whether the expansion slot is blocked by the fan or heat sink when the interface card is installed, and whether the cooling fan can fasten the CPIJ fan card slot, etc.
2. Quality
cooling fans are also divided into boxes and bulk. Usually boxed cooling fans are marked with many related technical specifications on their packaging, such as the speed of the fan itself (unit is r/min), power, etc. In short, easy installation and good heat dissipation are the most important considerations when choosing a processor fan. If you plan to overclock, you can buy brand-name products with better performance when you choose.
The above is a detailed introduction of how to choose a CPU cooler. Finally, I remind everyone that there are counterfeit INTER and AMD fans on the market, so you must pay attention when choosing.
