Radiator development has always been accompanied by two major themes of heat dissipation and mute. To improve the cooling function; the simplest method is to improve the speed of the fan; the noise will also increase after the fan speed is improved. At this time, the noise comes from two aspects; Cut the air's call and call; on the other hand, the sound of the friction of the mechanical equipment of the electric fan; this sound is from the bearing. Some radiators whose quality is not close; often the fan makes it worse; if you buy it Kind of product; you can enjoy the fear noise brought by the bearing in a short time.
Important relevance: one page after reading one station to get the evaluation of the major website radiators can be summarized; as an important part of the fan, how many bearings are important to our radiators; the following fan bearings are more common in the market; Let's take a look:
Oil bearing Sleeve Bearing
Oil bearing: This kind of bearing can be said to be the old bearing skill in the market today; however, because the cost is low; the skill is simply completed; many products contain well-known brands are still using the edge; its strength is the initial Quiet when used; low noise; cheap; but usually late because of the evaporation of internal fuel and the entry of dust; severe wear on the bearing; then slow down the speed; increase the noise; the average life is only 8000 ~ 15000 hours.
The radiator of the Thermaltake Jungle 512 is the oil-impregnated bearing. It uses a 9032 fan; the size is 9cm x 9cm x 3. 2cm; and the extra operating current is one amp; this fan with oil-bearing bearing as the center The air volume can reach 54.91-87. 70CFM; the speed of the fan is 2300~3600 rpm. The Thermaltake Jungle 512 can adjust the speed of the fan according to the temperature condition; the acoustic noise can be adjusted between 29.5dBA and 43dBA.
Laifu Bearing Rifle Bearing
Rifle Bearing: Rifle Bearing developed by CoolerMaster uses the core with reverse spiral groove and oil sump; oil in the fan operation will constitute reverse migration; then prevent oil loss; as oil bearing The modified type; Laifu Bearing has been promoted to the service life of the bearing. From the cost and oil-bearing bearings, there is not much promotion; it can be said that the low-end product center is a better economical treatment method.

The fan of the Thermaltake Jungle 512 radiator is the oil-impregnated bearing. It uses a 9032 fan; the size is 9cm x 9cm x 3. 2cm; and the extra operating current is one amp; this is centered on the oil bearing. The air volume of the fan can reach 54.91-87. 70CFM; the speed of the fan is 2300~3600 rpm. The Thermaltake Jungle 512 can adjust the speed of the fan according to the temperature condition; the acoustic noise can be adjusted between 29.5dBA and 43dBA.

Magnetic suspension hydraulic bearing HYDRAULIC Bearing: The magnetic suspension hydraulic bearing technology introduced by AVC uses magnetic support suspension and the special oil film smooth with it; usefully handles the opposition between the long life and low noise of the electric fan.
AVC's Lishan radiator is a radiator that uses magnetic suspension hydraulic bearing technology; it uses AVC's high-end hydraulic bearing 8025 fan; the fan size is 8cm x 8cm x 2. 5cm. The operating current of this fan is 0. 7A; the fan speed is about 4300 rpm; if it is the use of full-speed ball bearing fan noise is very scary; because this fan is the choice of hydraulic bearings; and the temperature control function on the motherboard; noise control Satisfied.
Nano bearing NACOOL Bearing
Nano-bearing NACOOL Bearing: introduced by FOXCONN; the new bearing materials made of nano-composite materials have a good performance in high temperature and wear resistance; this kind of bearing can be used to improve the anti-wear ability of electric fan bearings; The use of the environment will not be affected too much; the service life is more than 120,000 to 150,000 hours.
There are different differences between the radiator products that use these bearing skills in the market; the most simple is the difference in price; knowing these differences can help us to decide according to individual needs when purchasing radiators; It also prevents some merchants from shoddy; let the individual spend money and can't reach the role that the individual wants.
Summary These types of bearings are widely used in the product; and the products of the big manufacturers are often more concentric; finally give us a comparison table; let us have a ruler at the time of purchase.
