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

I basically cant hear it. I just needed to replace a venting fan, so Im not sure how great the air flow is, but it is super quiet.

Using it as a rear position case fan.

Easy to install. Premium braided cabling. Premium quality build. I need two more, when you guys restock please let me know, I will definitely be buying more.

Great Price, low noise. On time a day early actually. Package came in perfect condition.

These fans do exactly as advertised. Quiet effective cooling.

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

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.

Great fan at a great price. Quiet, low rpm, and pushes air at a high level.

Ive had these for a couple of months now. Out of curiosity, I set them to 100% and all I could hear was wooshing from the air.

This is the fan that came with the Scythe Mugen 5 cpu cooler. Bought an extra one to mount onto the cooler but it turns out 1 of those was more than enough for my delidded 8600k running at 5.2ghz. Currently its acting as my exhaust fan in the rear. Runs so quiet I had to stick my hand behind the case to make sure its running. Considering buying a few more to replace my other case fans. 5/5 will recommend.
