The shell is made of excellent material, , strong, - and aging-, 100percent new and high-quality, improves air flow, and cools your CPU. Integrated heat dissipation, the fan blades are not easily deformed, the wind is stronger, the operation is stable, the high-precision bearing, the vibration is small, and the service life is longer. Precise hole position, firm installation, no falling off, more convenient and convenient installation, large air volume, low noise, fast start-up, low power consumption, low noise, low vibration, fireproof and waterproof.. The high-precision bearing adopts the form of rolling friction and adopts two . There are several tiny steel balls in the bearing that rotate around the shaft core, so the friction is small and there is no problem of oil leakage. High-quality pure copper motor, clear line resistance, 100percent copper wire wrapped, copper wire after 12 hours of insulating varnish soaking, high temperature resistance, low consumption and energy saving, suitable for: electrical appliances, computers, servers, power supply equipment, power supplies, household cabinet cooling Wait Although the version is small, each layer of the structure is manufactured with care and quality assurance.
