I had a Noctua D9L, a small cooler on a 7700k with XMP enabled and all cores at 4.5 GHz. In stress tests, I reached a maximum temperature of 87 degrees. So, I decided to try this liquid cooler. It made a terrible impression from the beginning, producing excessive noise both from the pump and the fan when it reaches 1,000 RPM, which is almost always. The temperatures in stress tests reached up to 93 degrees. I couldn't believe it. I changed the thermal paste and used MX4, I changed the fan and added two additional fans. I tried push and pull configurations, I did everything, but the temperature difference was only 3-4 degrees. I was disappointed with the size of the whole cooling system, the tubes, etc. In the end, I bought a Noctua U12S, which is completely silent, and now in stress tests, I have 81 degrees. We are always talking about the same case and the same external temperature. Ultimately, liquid cooling is not worth it unless you have a cooler with two 140mm fans.
