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.

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.

Good AIO
Dropped my CPU temps in my ITX build from around 80c under high load to around 70-72c. Installation wasn't too bad and for the price, it's awesome. Would reccomend, does it's job good.

Phenomenal Pump, terrible fans.
I used this in a sff build of mine and I was definitely surprised by its pump performance, compared to the be quiet pure loop 2 it was about 7 degrees cooler however the stock fans on this are just terrible and whine super loud when their on max rpm, I replaced them quite quickly with some lian li

Silent Pump, Great Cooling
This cooler works great. I'm coming from TWO EK CR240 coolers that developed grinding pumps within a month. Installing this, the pump is dead quiet, and using the same fans (Phanteks T30) and same thermal paste across all of them, this runs about 5c cooler than the EK coolers. It could be the large difference is due to the pumps, which seem to have been defective. Either way, this cooler is dead silent and cools well. You don't have to use all of the RGB nonsense it comes with and deal with a big nest of cables, either. If you just want to install the cooler without fan RGB it's just the PWM pump header and the fan header on the mobo. You can plug the pump head in to any 2nd gen RGB plug on the motherboard, too. It's a very clean install overall.

Worth it 100%
So far an amazing cooler that looks absolutely stunning in a white build, great for small builds and easier cools my CPU with no issues, if anything, this increases the available performance and is a great value for its money.

Perfect
I put this in my T1 and honestly the best. The pump is quiet, and the tubes were very easy to work with.
