First time I go for liquid cooling with the purpose of going overboard and creating a nice build. Really, the result has compensated me.. whatever I say is not enough. It was installed on an Intel i7-12700K (12-core) and in the Lian Li O11 Dynamic EVO Gaming Midi case with a completely light overclock on the system from the Asus default.
I am no longer particularly involved in gaming, so I won't comment on anything related because I haven't tried it there, but at some point I will install GTA to see how it goes. What interested me mainly, apart from the aesthetic aspect, was to keep low temperatures at idle and under relatively light load with browsing and a few programs, so that it is silent under such conditions.
Together with its application, it works wonders, it has many settings, you can change the linearity in the speed increase relative to the temperature, you can keep a constant speed for a range of temperatures, etc... I set it to work steadily at around 300rpm up to 37 degrees and then increase the speed linearly. After 600 rotations, you start to hear the noise, but because I have 10 fans in the case, I don't know how much the ones from this cooler alone are heard. However, when I tried it at full speed, you would think it would take off...
Generally, with the setting I made at 300-400rpm to be completely silent, it keeps the temperature at 28 degrees at idle and instantly reaches 37 if you stress it with multiple programs and a 4K video and above. I also wondered if it has a pump noise because it works at full speed, but you can't even hear it up close.
As for the negatives, I will mention that its instructions are not clear regarding the connection because it has 2-3 ways to connect them and it doesn't explain anywhere how to synchronize the RGB from its fans and from the CPU with another 10 fans, the motherboard cable, and the lights in the case... It becomes a mess, it's better to find someone who has done it before so you don't waste your hours on YouTube...
Is it worth its money for 200 euros? Yes, if you are building a high-end PC of 2000+ euros, which means you have the financial comfort. If you are struggling to stay below 1000-1200 euros, then definitely not, there are other solutions.
