    I have this in my newest system and extremely quiet. I also have a Cooler Master Hyper 212 Plus and this is quieter to me. I also got for $20 without a rebate and free shipping.

    For the money spend is excellent. Much better performance in thermals and acoustics that the stock Intel cooler. It is almost whisper silent even @ full rpm Its short so it will fit most cases, plus the installation is a piece of cake. It is able to handle a small/moderate overclock on coffee lake cpus. Is good looking too in my opinion.

    For the most part, temperatures stay below 50 C and only under full stress does the temperature rarely get above that. even under full load, my case fans drown out my cpu cooler, which aren't that loud. It is a bit large, but that may just be me. Only issue was getting the fan on since the wire that holds it on really hates bending.

    Swapped my Corsair H100i GTX to this, Why I hear you ask? Well because my PC sounded like a fish tank and my CPU is only 2 degrees hotter when under load and overclocked.

    The cooler looks great, simple to install and hardly makes a noise under load.

    Thank god for German engineering.

    Great cooler, effective at keeping temps down. A little on the tall side, so be sure to check clearances. Effectively silent!

    This cooler is amazing. It looks great, it's incredibly quiet, but the mounting and install is weirdly complicated. The fan is mounted with a sort of hinge-like thing, and that seems unnecessary.

    Cheap and cools really well while remaining dead-silent! What more do you want?

    Blocks the first RAM port on the AsRock Fatal1ty AB350 Gaming K4 mobo. Instructions weren't very clear, had to YouTube some things. Feels like it was mainly designed for a Intel CPU. Otherwise it's a great cooler and super silent!

    from completed build I5-6600k - R9 Fury - First Build

    Other then being very large and bulky I think I am very happy with it. Not sure what the temps would be without it but I assume it is doing a good job. Very quiet and doesn't look too bad. Cons are size, and blocks RAM slot.
