> 3 dayA lot has already been said about these excellent fans. I especially like that they come standard with the 4 pin PWM connectors at a very reasonable price point. The Scythe Kaze Flex worked perfectly with my Z390 Aorus Pro board, and the screw holes aligned perfectly with my somewhat aging Centurion 5 case making this a drop in replacement for my failing Cooler Master fan. If you are looking for a 120mm PWM fan that doesnt have the 50% PWM surcharge, consider this one.

10-04-2025I purchased 5 of these fans to replace the standard fan in my Fractal Meshify C case. I noticed an instant increase of airflow and slightly lower temps. With all 5 fans running system is quieter than before with only 2 standard fans. Great price to performance ratio for me.

> 3 dayReplaced a noisy fan in my pc with one of these, and I can barely hear it. I will definitely be replacing more of my fans with these.

Greater than one weekI got a pair of these fans to be used in a PCI bracket to cool off the GPU (MSI RX580 OC). In pursuit of a quiet computer, the stock GPU fans were very loud.

> 3 dayAbout as quiet as the bquiet silent wings at full. But for the same price they have less case vibration, a braded cable and are 4pin. Im going to get these for now on

> 3 dayI am really impressed with the quietness of these fans. I purchased two 120mm fans and mounted them side by side inside a full size tower ATX case. There was hardly any noticeable additional fan noise created by these fans. There is a rubberized material in the four mounting corners which I believe is to help reduce vibration.
