Unique combination of two patented fan design of the Torx Blades of MSI combines the power of two different fan blades: Traditional Fan Blade creates a stable air flow dispersion fan while the blade has a steeper than curve, which speeds up the flow of air and increases its efficiency. Bearing and super silence gently turn on self-lubricating HDB, the fan has an extreme long life in constant operation. Integrated Anti-Vibration Pad made of soft silicone rubber to reduce vibration between the fan and the additional chassis, anti-vibration pads prevent noise static air pressure: 0.16 – 2,09 mm-H20 life expectancy of MTTF: 150,000 hours (25 °C)
