The Silverstone FQ91 represents a perfect balance between performance and low noise.
It has dimensions of 92x92x25mm, white and blue blades. It has a PWM function which allows the motherboard to control the fan speed and adjust it depending on the internal temperature of the PC. Its dual blades are tailor-made for better air pressure performance. All these features not only improve ventilation but also reduce the sound level. Integra PCF Bearing Bearings (Copper Fluid Powder Bearings), which will make the Silverstone FQ91 have a lifespan of 150,000 hours. We highlight ... * PWM fan 92x92x25mm. * Adjustable speed: 1000 ~ 2500 RPM.
The fan rotation speed will be automatically adjusted between 1000 and 2500 RPM, generating an air flow between 19.8 and 44.2 CFM and a sound level between 14.7 and 24.8 dBA.
* Optimum air flow and pressure with extremely quiet performance. * Innovative blade design that concentrates air flow and optimizes efficiency. * High air flow: 19.8 ~ 44.2 CFM. * Low noise level: 14.7 ~ 24.8 dBA. * Connection: 4-pin.
