Features: The 15mm thickness take up less space than the traditional 25mm thickness and reduces interferences with the motherboards and graphics card. Suitable for various small chassis. 4Pin intelligent temperature-controlled fan supports PWM temperature control and speed adjustment, balancing performances and noise. It adopts the 9 leaves design and silicone shock-absorbing pad to reduce chassis resonance, easily achieve low noise to achieve high-efficiency output. Using hydraulic bearings, the speed is stable, reducing wear and noise, durability and quiet There are shock-absorbing rubber pad on both side of the corners, which can effectively absorb vibration at high speeds, reduce resonance noise, and make the operation more stable.
