Easy to mount Ease of setup Not too loud Excellent performance, keeps the beast that is a Ryzen 9850X3d running cool, and isn't that the whole reason to buy a cooler. Great price to performance

Quiet and effective. Install (replaced an existing AIO) was pretty straightforward. Been running for about a month with no issues. So far under load max temp was 71 C on a Ryzen 7 9800X3D

Best 420mm AIO on the market. Dead silent even when the pump is on max (I run it at 70% but tested it higher). I think the RGB looks very classy. Excellent value for what you get, and this thing is built like an absolute unit. The tubing is very stiff, but it's hardly a reason to knock a star off.

Been 1 year since I upgraded from my be quiet! Dark Rock 4 CPU cooler, for my Ryzen 9 7900x. This was easy to install and had many how to videos on the manufacturer website. Noticeable difference in temps since the upgraded. Used to be in the 80s° to high 90s° and my pc used to always ran hot. Now my cpu temps are in the range of 65° to 74°. For me the fans are not loud even if its running on full speed. If your looking to upgrade to an AIO cooler and without spending a lot of money this is worth it. Great price and product.

I wish I could rate this cooler higher than 5 stars. I upgraded from the (still excellent) Arctic Freezer 4U air cooler because my use case changed to require a liquid cooled solution. After searching through frankly overpriced options ($600+), I found this model. Even at full retail, this product is an absolute steal. I am using the AIO with an AMD EPYC 7F52 (240W TDP), utilizing the seamless fit of the Threadripper (sTRX4) bracket on the SP3 socket. The performance is phenomenal: At idle, the temperature sits between 16C – 19 C (though, room ambient was around that, so you can expect near ambient room temperatures on the cpu under normal usage ). Curious, I ran Prime95 to pull the full 240W. The CPU would not exceed 48C. To call this product overkill is an understatement. It cools so effectively that the air pushed out by the fans is cold enough to turn your fingers stiff, thankfully computers are far more cold tolerant than my hand. On top of the raw performance, the build quality is like a tank, and the installation took barely 10 minutes thanks to the clear instructions. I highly recommend this product to anyone. Whether you're cooling an ordinary gaming CPU or a high-wattage server/workstation chip, this cooler can handle it, with included mounting brackets for both use cases. Buy this, put it on your CPU, and it will likely never feel what anything higher than 50C feels like again.
