I have it for two years, you can't even hear it, it has better fans compared to a Corsair I had (H75). I have it on Ryzen 5 1600. The installation was very easy, a little difficulty one may have only in organizing the cables for the fans for the first time. The pre-applied thermal paste is very good. The installation on the processor is a piece of cake. I highly recommend it without hesitation!

I can say that I have loved it, it is very high-quality construction, very beautiful and simple. It is very convenient that it has a regulator for 3 fans on the CPU block, in auto and PWM mode. It has very good fans on top, it is incredibly quiet and on a Ryzen 5 1600 OC at 4GHz, it keeps it at full load at 56° and idle in winter around 25°. If you have space in your case, get it. I have had it for a year now and it has not given me any issues so far, even though it has a 5-year warranty

At the 102 euros I bought it, we are really talking about a tremendous deal. Excellent construction, exemplary packaging, and the fans work perfectly. Of course, we shouldn't forget to mention that it has the ability to be converted into a custom liquid cooling system with the addition of radiators, a pump, etc.

Update: 9 months later, I am writing because now I have seen it in both winter and summer. Coming from a 212X in terms of temperature, I saw a decrease of 5 degrees in idle (from 35 to 30-31) and 10 to 12 degrees in load (from 62-63 to 52-50). It makes a big difference in terms of sound, where you can't hear it at all under load compared to air cooling. In general, I would say that I am very satisfied and I have not regretted transitioning to liquid cooling from an aftermarket air cooling. If your case can accommodate it, it is worth it.

Specs: 3570K at 4.6, Gigabyte Z77XUD5H, Corsair 750D with the liquid cooling on the top in a push configuration
