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

was iffy on these fans, as i have never used the brand. So i went ahead and got them, upon starting up my pc, i could feel the fans moving lots of air. they are quite. And that is 2 of my main things i look for with pc fans. These things are not Noctuas. But they are very very close. cables are nice and braded. the antivibration rubber pads do their job. I would buy these again. Just make sure to get PWM.

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.

Installation to add to other side of Mugen 5 was a snap. Installed with provided clips from previous Mugen 5 purchase without removing cooler from heat sink. Works as well as the identical fan that came with my Mugen 5. My 3600cpu runs 10c hotter than my 1600af did at idle 48c and load 67c . Temps were within specs but I still wanted to keep it cooler. This cut 5-7c off the difference. Using on a MSI B450 pro carbon. I only saw one CPU header on MB so plugged this 2nd fan into the pump fan connector on the MB. It won’t control the fan speed identically to cpu fan without a fan splitter. I just got around to ordering the splitter 2/7. If it doesn’t work as I suspect I’ll update review.

These have great flow characteristics on low fin heatsinks, like those found from scythe, and cases. In both cases, they are extremely quiet, more so than the Noctua Redux that I replaced, where at 1200rpm you could hear the buffeting air with the noctua. Not that it was a bad sound mind you. It is much better sound than the noctua is what I am saying though. May system is running cooler with these, but that is my case supports 3 120mm or 2 140mm. So getting these allowed me to add one more fan verse the 2 140. This offers better pressure characteristics and encourages flow.

I got a pair of these fans to be used in a PCI bracket to cool off the GPU (MSI RX580 OC). In pursuit of a quiet computer, the stock GPU fans were very loud.

Perfect fit for my Scythe Fuma 2 CPU cooler.

Quiet and effect fans that work great. The gray coloring made these far more attractive looking than other fans in this price range.

Good product, excellent value.

It blows! Nothing pretty but its quiet and gets the job done! I dont really care too much on the look of my computer, its a natural looking and great fan!

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