Its performance is on par with the Scythe Fuma. It keeps the i7 8700 @ 1.2V at 40 over ambient under non-AVX load. Regarding the performance, I have the following to note. Due to the thin radiator, it reaches equilibrium quite quickly compared to other AIOs and has nothing to do with 240mm+. The fan for the VRM is not decorative, but don't expect miracles if you don't have an exhaust fan directly above. Other than that, it's absolutely silent, no pump noise, the fan is barely audible.

A few additional points:
- It's incredibly positive that the entire circuit is powered by ONE SINGLE fan cable for the pump, fan, and VRM fan.
- I hear a lot of complaints about the installation, honestly without reason. There are informative videos on YouTube for installation on common sockets.
- A negative aspect is that the radiator protrudes both above AND below the fan, resulting in it not being able to be placed in panels that barely fit your fans, which is why I gave it 4 stars.
- Install the AIO so that the block (which also houses the pump) is lower than the radiator to prevent it from drying out and starting to make noise due to air in the pump.
- As with all AIOs, anyone who tightens them too much on the socket will crack them and water will leak. The same will happen if you stretch the hoses too much.

UPDATE 19/10/20
I upgraded to 8700k. At 4.8GHz with 1.25V set/1.241V get, we are at 48 degrees over ambient under non-AVX and 56 under AVX loads.

Amazing AIO, especially if you don't have much space in the case for a larger air cooler, it's just right.

I have it on a Ryzen 7 2700, overclocked @4.0Ghz 1.3V, and it cools better than the Noctua NH-U12S and the Arctic 34 Esports Duo, by 3-4 degrees. In the Cinebench R20 stress test, it reached up to 73 degrees, in summer (with a temperature of 30 degrees). In gaming, it doesn't exceed 50, in any game I tried.

One downside is that its installation is very difficult. It took me about an hour and a half, and I needed a second person.
