Review on Razer Kunai Hydraulic 120MM ARGB PC Fan: Quiet, Powerful ARGB Fans - PWM Fan Controller Support & Connect Up To 8 Fans - Powered By Razer Chroma RGB - 3 Fans by Matt Jenkins

I really like these fans. I just helped my son build his first computer which he worked with me and saved up for an i9 12900K, 3070ti. He was leaning towards the Lian Lu fans but I let him test these review units in his computer. We both agreed that the build quality of these is very good. They feel precision made, smooth operating and quiet. Even at full speed the blades don't seem to make as much of a whine or whirling sound. They also move a lot of air. We tested them exhausting air which is the front side in orientation. We also reversed them with the backsides facing in to use them as intakes. You can see the wires exiting and the backside of the fan, but the LED's still look the same on either side. He decided to spend his money on another set so that he now has all Razer fans. We both agree that these get 5 stars. They are premium fans. The price is premium, but they do seem to reflect that in the quality and performance.
