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 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.

The fan performs amazingly. It pushes the highest amount of airflow out of all the competing 120mm fans and does so while being very quiet. Recommended purchase :)

I am really impressed with the quietness of these fans. I purchased two 120mm fans and mounted them side by side inside a full size tower ATX case. There was hardly any noticeable additional fan noise created by these fans. There is a rubberized material in the four mounting corners which I believe is to help reduce vibration.

Great product. Its the quietest of all I have and puts a great amount of air.

Ive ordered 3 of these fans so far and the first two are super quiet and are residing on my Cooler Master 212A EVO, silently keeping my gaming CPU I5 9600K cool. The 3rd one is residing on the side panel of my Cooler Master 690 and even though it is set to Silent in the BIOS it will still hum a bit too much at times. Otherwise these fans would have been a solid 5 stars all the way.

Needed more fans for more air circulation. Added 3 of these plus the stock 120 lian li fans. Super silent compared to the stock fans. Lots of difference with pc temps! Will update if I have any issues, but so far I am pleased. Great for the value.

Used as a rear exhaust. Very efficient and quiet. Exactly what I needed!

There’s not much to say. The fan is slim and quite. It makes small cases work.

Value

Easily one of the best fans you can get. Scythe never disappoints.
