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 Melvin Goerge

The bottom line here is that these are up to the Razer standard - they are good quality, well-made and they perform. They move a solid amount of air for their size/RPM and seem like thy'll last a long while. They're easy to install and they come with both rubber pull through mounts (for vibration dampening) and screws for a more solid mounting. (I ended up using three of the pull throughs and one screw on each fan - using all four pull throughs didn't keep the fans in the right position - but all four screws would have increased the noise.) The RGB is really nice - with an aRGB ring on both sides so it shines nicely though but doesn't diffuse like fans that have the LEDs in the central hub or as "mini-spots" shining in - controlling it comes through the device you plug the aRGB leads into, so in my case through my motherboard.So why only 4 stars instead of 5? Two things really. First, Razer prioritized performance over sound here so they're a little louder than similar fans from completing manufacturers. Second, in part because of this, they're not a very good value for money at over $43/fan even in the three pack - you can get similar performance (and a bit quieter) for less - but they won't look as good, that's for sure.
