ARCTIC ACFAN00137A P12 PWM PST 120mm Black Case Fan - 5 Pack

I was shocked when I picked up the box containing these fans. It's heavy! Each fan has a weight to it and feels rock-solid. They push the air efficiently and when I switch my PC on, I have to double-check as I don’t hear anything. It's only at the very high RPM-range where you hear them and it's hardly necessary for them to run at those speeds.

They are much quieter than both Cooler Master and Gamdias fans that I've had previously. I can highly recommend

Fans feel like high quality out of the box. Daisy chainable connectors helped with less cables to manage and they are whisper quiet if installed properly.

Does it's job at a good price for 5.

After some time with these fans I have changed my mind, they are the best for the money by far! Quieter than even the Cooler Master Mobius OC, which is louder than a jet taking off right next to you, even when they're at 1500rpm.

Yes they are good value for money and look good, they have decent airflow and can be quiet from around 500rpm to 1200rpm, anything lower or higher and it makes some of the most irritating sounds I've ever heard from a fan, whining and drone-like humming.
Maybe my expectations were too high, but they seem overhyped to me.
