Scythe Kaze Flex II PWM, 120mm, Premium Quiet/Silent PC Computer Case Fan, Quiet Model, Low-Noise Optimized, 4-Pin, Deluxe Black Colour, Single Pack

It arrived early. It is a very quiet fan. Great value for the money.

Quiet efficient airflow. Does not disappoint, just like the video reviews claim. Scythe has been around for awhile, so they must be doing something right. Stylish color scheme. The rubberized corners help to dampen vibration and noise. Easy to install.

these are awesome

Great quality fan, and silent. Everything from this brand is awesome.

This was a second fan added in addition the primary fan on the Mugen 5 Rev B. It works great and I couldnt be happier.

Scythe has been my Go-To case fan for a while. I like slow & quiet. That being said, these are their slowest fan, and there is a limit to under-volting them. Specs say 300-1200 rpm, but they don’t start up reliably if running under 600. Still very happy with them.

Will not spin up at any voltage or fan setting. Have to spin it with my finger first, then spins up. Only a couple of weeks beyond the return window, oh well. Do not recommend.

I dont remember giving anything a 5 stars review, but this fan definitely is worthy. I built a Core i7 11th gen budget PC, which is known to run very hot. With a stock case fan, the CPU was idling low 50s degrees C, and just light to moderate load caused the temp to go up to 70-80 degrees C. I saw a comparison review on Youtube where the author gave this fan a good review; in fact the author recommended this one over the more expensive Noctua and Artic fans. Considering the price, I decided to give it a shot. So I replaced the stock case fan with one of these and added another one to the front of the computer case. The result: CPU now idles mid to high 30s, and at 100% load, barely reaches 70 degrees C. My GPU also dropped around 10 degrees as well. Im really happy with these results because Im not a heavy gamer, so most of the time, the CPU will be around 40-50 degrees. The noise level is totally acceptable; I dont have metrics to give, but just judging from the ambient noise, this fan is very quiet. Considering the price and performance, I would go back to this fan any time I build a PC. Just remember the general rule to channel the air in one direction for all the fans inside the case; in my case, all the fans work pull air from the front and push out to the back of the PC (dont forget the orientation of the CPU fan as well, if applicable). Highly recommend this fan.

Moves adequate air with low noise at a fair price. Would use again.

Like everything about this fan!
