> 3 dayI 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 dayThese are great case fans at a great price. If anyone is saying theyre loud, theyre being stingy and want absolute silence. Bought 2 of these as front intake fans and they provide great thermals despite them being used in an NZXT H210 which isnt great for thermals. Theyre quiet even on load, and still quieter than my Zotac 3060 fans on idle. Would definitely recommend these to anyone that want competitive performance versus Noctua fans without the price premium. Just wished these came in 3 packs at a slightly cheaper price since these are still hefty compared to some other fans like the Arctic P12 which does come in multi-pack despite being cheaper.

> 3 dayThese fans are quiet. Main reason I use these in my builds. They can run at lower RPMs than other models in my experience.

Greater than one weekA 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.

> 3 dayI cant even hear it and the rubber corners really do help stop the vibration in my case unlike my last fans

14-04-2025Noise level on Normal settings in BIOS in much better than the cooler master sickleflow 120mm that came with the nr200. The vibrations buffers on the fan housing is just outstanding. Sleeved wires make cable management that much nicer. All in all, a great buy for the price.

> 3 dayId go with Arctic for quiet fans that cool well. [If you dont want to spend a fortune on Noctua fans]
