Review on 🌀 ARCTIC F9 PWM - 92mm Case Fan, PWM-Signal Regulates Fan Speed, Ultra-Quiet Motor, Computer Fan, Speed: 150-1800 RPM - Black by Adisorn Wichit ᠌

I put two on the tower 775 CPU cooler. They work quietly. Quieter than native dipkulovskih without speed control. Silence. Its pros: Quality , performance, low noise by 4 points. The kit includes a splitter for connecting two to one connector. hydrodynamic bearing. The best combination of price / quality / performance / noise! Its cons: Noise level by 4 points. It would be quieter, but I think it's the noise of the air currents. We need a different design of the blades and diffusers.
