1Pc 4028 12V 1A Dbtb0428B2G High Speed Server Fans 40*40*28Mm Dual Ball Bearing 4-Wire Pwm

Description: 1. High-Efficiency Heat Dissipation: 12V 1.00A high-power configuration + optimized aerodynamic fan blades generate strong concentrated airflow, quickly expels accumulated heat inside server cabinets, effectively prevents component overheating and extends device service life. 2. Ultra-Low Noise Operation: Precision dynamically balanced fan blades + dual ball bearing design reduces running friction and vibration, keeps noise output at a low level even at full speed, avoids noise disturbance to server room working environments. 3. Long-Lasting Durability: High-precision ball bearing material has lower friction coefficient and better wear resistance than sleeve bearings, supports 24/7 continuous stable operation, greatly reduces fan replacement frequency and later maintenance costs. 4. Intelligent Speed Regulation: 4-wire PWM speed control cable with copper core conductor supports -time intelligent speed adjustment according to device temperature, balances cooling performance and power consumption, improves energy utilization efficiency. Specifications: Material: Dual ball bearing, flame-retardant engineering plastic housing, tinned copper core cable Size: 40mm × 40mm × 28mm (4028 standard size) Color: Black Application: Servers, industrial PCs, network communication cabinets, small electronic equipment, compact cooling systems Quantity : 1 Piece Note: 1.
