Quiet but Large! 1/28/2020 6:11:16 PM

Pros: Incredibly Quiet,
Install was easy enough - or find an install video and it all makes sense
Black color scheme works well for my setup
Fan CAN be put on opposite side to allow 4 sticks of RAM, but I installed the regular way

Cons: So large that it blocks 2 channels of RAM - could move fan to opposite side, but meh.
Paint can scratch easily when installing fan, as it is held in place by pressure - not enough to complain, but should be mentioned.

Overall Review: I love this thing! My whole setup is insanely quiet now.. to the point I don't know if the desktop is on or not! Will be purchasing more "be quiet!" brand fans to replace others in my case.
Keeps my I7-9700k nice and cool, running smooth as butter!
I would suggest getting 2 sticks of larger capacity RAM, as the cooler CAN block 2 RAM channels - or at least it does on my MSI-Z390 A-Pro mobo.
BUY ONE!!!

Effective and Adaptible 12/22/2019 6:33:53 PM

Pros: Quiet. Moves air. Keeps things cool.

When the fan in the default location interfered with the memory, the hardware supplied was able to be reconfigured to move the fan to the other side of the heatsink while still pull air in the right direction. Fan position can be in front, rear, pushing or pulling on either side, and moved up or down with included hardware.

Cons: Its tall. In a standard ATX tower, it fits. But anything else may have issues.

Overall Review: Adapable cooler so long as you have the height.

Great but won't fit 7/27/2019 7:21:47 PM

Pros: - it can keep 9900k within 34-69c (not OC)
- very nice design and look.
- silent fan.
- high quality materials.

Cons: - I have Aorus Z390 master and it won't fit with 32gb (x4 8gb) memory (Gskill rgb traidnetZ) and i couldn't figure out if there is another way to do it. so I had to use only 16gb (x2 8gb) .
- fan installation can be really annoying.

Overall Review: it doesn't fit my application but it's really good product, high quality + good price. I might give it to my friend and buy a liquid cooler.

Super Impressed! 7/19/2019 1:11:47 PM

Pros: -My case fans are louder than the cooler
-All black fits my case
-Temps are very good under load and near silence
-Max temps on ryzen 3700x are 65 C

Cons: N/A

Overall Review: INSTALL CORRECTLY!
My first installation resulted in extremely high temps and I realized the mount was not lined up correctly. After re-installation it worked like it was intended to. Make sure it does not move around when mounted; it should be very secure.

Love be quiet! 7/12/2019 8:46:15 AM

Pros: - easy to install
- comes with their own screw driver
- comes with multiple fan "arms"
- Intel/AMD stands

Cons: - attaching the fan was a bit of a hassle because removing it from the cooler required me to pry with more force than I'd like to

Overall Review: Love how quiet this fan is, can barely hear it even with the side panel taken off.
