Review: Keeps CPU cool even when over clocked! - Fantastic cooler. Monitored temps for the first few weeks and it keeps my Ryzon 7 cool even when over clocked. Extremely quiet and functions perfectly. It is not bulky so it fits easily in my case. I highly recommend this cooler.
Review: Excellent Cooler That Fits In The Dan A4-H2O - This was exactly what I was looking for - it fits perfectly in my Dan A4-H2O. The packaging was easy to work through, and durable enough that I'm holding on to it should I ever uninstall this AIO. I put some Noctua fans on it, and it cools my 7800x3D excellently. Installation was pretty straightforward, there weren't a crazy number of cables to manage, and the tubes are flexible enough without feeling too Pinner. The RGB effect is pretty great as well. I would definitely recommend this cooler.
