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.

I recently upgraded my PC with the Cooler Master 240 Atmos White AIO cooler, and it’s been a game-changer. The white and RGB design looks sleek and fits perfectly with my build. Installation was straightforward, and the included thermal paste and accessories made the process smooth. The SickleFlow Edge fans are impressively quiet, even under load, and the cooling performance is top-notch, keeping my Ryzen 7 7700X cool during heavy gaming sessions. The customizable pump cap adds a unique touch, allowing me to personalize the look. Overall, it’s a solid cooler that combines aesthetics, performance, and ease of installation.

Amazing cooler. Cools my 9800X3D inside a Lian-Li A4 H2O keeping it cool at around 60C in game and maximum of 80C in stress tests like Cinebench and AIDA64. Pump is quiet and the included fans are decent. Would purchase again for another build.

Funciona bien, pero peor de lo esperado en climas cálidos, vivo en donde la temperatura ambiente llega a 30-37 grados en días normales, y si bien la pagina dice que el TDP es de hasta 270W, le cuesta mucho enfriar el i5 14600KF, que consume hasta 180W, en videojuegos va perfecto pues no consume más de 125W y la líquida es capaz de enfriarlo, pero cuando renderizo videos apenas puede, lo consigue mantener a máximo de 95 grados y promedio de 92, pero para la gente con aire acondicionado irá perfecto (con el aire acondicionado a 24 grados, incluso renderizando por 10min no supera los 84 grados), para mí, quedó muy justito, pues casi nunca tengo el aire acondicionado prendido, pero pues como renderizo poco tiempo no lo veo tan grave. Tuve que hacer un ajuste en la BIOS para indicarle a la tarjeta madre que tengo refrigeración líquida, porque si lo dejaba en las configuraciones predeterminadas funcionaba HORRIBLE, pero eso no creo que sea culpa del producto, tal vez es un tema de la placa madre MSI, pero al indicarle correctamente que se tiene refrigeración líquida instalada, funciona como debería, en general contento con el producto, excepto por: El HUB que viene para controlar el RGB con el programa MasterCTRL dejó de funcionar a los 2 meses, por suerte mi placa madre tiene puertos para el RGB y pude conectarlo a la placa madre sin problemas y volver a tener RGB, espero eso no sea un problema recurrente en todos los HUBs de esta líquida porque si te da un susto, cuando dejó de funcionar apagó mi PC e intento prenderse sola como 4 veces y no pudo, creí que había perdido toda la PC pero por suerte solo era el HUB.
