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 replaced two original 120 mm Corsair CPU water cooler radiator fans with these Scythe fans and drastically reduced the sound. The 4 wire control and my mainboard fan profiles allowed me to match CPU temperature to fan speed. In addition, I downloaded a free utility called Argus Monitor that also enables fan profiles and monitors all mainboard temperatures, which is super nice. If want a silent system, Get These Fans !!!!!!!!!!!!

Excellent cooling and very silent!

Silent and efficient. These puppies are quiet, even at max load! You wont hear much bearing noise, only the wind turbulence.

I purchased 5 of these fans to replace the standard fan in my Fractal Meshify C case. I noticed an instant increase of airflow and slightly lower temps. With all 5 fans running system is quieter than before with only 2 standard fans. Great price to performance ratio for me.

These fans do exactly as advertised. Quiet effective cooling.

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.

Excellent fan, very quiet, draws little power.

Before purchasing these, I watched several reviews/comparisons on YouTube and wanted to give it a try along with Arctic P12 fans. I also have several Noctua fans like the S12A and A14.

I got two of these as exhaust on the top of a CM NR200 build I put together for the wife. They are working wonderfully so far. Very quiet. And exhausting enough air to help keep the system under control. I wanted some black noctua fans but they were out of stock on the slims and I didnt want a bunch of different brand fans. Glad I went with these so far. Much cheaper and performing just as well.

These 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.
