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

These fans do exactly as advertised. Quiet effective cooling.

This fan matches the one attached to my heat sink.

I added two of these to a new build last week and they perform well. During Cinebench and IBT benchmarks, they ran at max and only gave a pleasant hum to let me know they were happily working. The rest of the time they were quiet. I will buy these again.

Replaced 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.

While I havent tested with a decibel counter, these fans are hands down quieter than the quietest cpu fan option available via amd. Settings on bios are on idle (quiet purr) unless to surpass a certain temperature, then they kick in with a turbo mode. On turbo (basically set to full throttle for gaming) then its an audible blast comparable to taking a leaf blower to the internals. Thats specifically for high or ultra settings gaming. Contemplating eventually swapping out the bundled cpu fan for another one of this type so then its all super quiet.

these are awesome

Ive bought 5 fans, no regrets so far :D

Very good fans for the money, bought two of them and theyre super quiet and work well in keeping my system cool. Great value fans and look nice!

Perfect fit for my Scythe Fuma 2 CPU cooler.

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.
