        Even better than model 2

        Despite changing the fluid and removing the bubbles, a temperature protection shutdown made me decide to switch to the SL3. Problem found: solidified dust (baked on) in the radiator fins. Impossible to clean properly. Extreme heat, fires and Sahara dust/talc are terrible.
        Worth noting:
        - Like the SL2, very quiet operation (BeQuiet Silent Wings 140mm fans). The PC is next to me on the desk and the sound is soft and fades into the background.
        - Used as it was 5 years ago, with the Arctic MX-4 2019 paste (4 grams). During the change, the paste wasn't even dry...
        - Unlike model 2, the cooler head is bigger than the processor! Probably to be compatible with large processors. There is therefore additional air cooling on the perimeter, and the head can absorb more heat mechanically.
        - Make sure to separate the 2 inlet/outlet tubes, otherwise you will reheat the cooled liquid flowing back down if the tubes are touching.

        Makes noise

        I had another water cooling system before that was great, but this one is noisy. I don't know if it's the product or the installation.

        Very good

        Very quiet, good cooling even under load. Clean mounting, solid pipes, and no parasitic vibration. The only 'fault': assembly requires a little more precision than other AIOs, but once in place it's a tank. Excellent thermal performance with a 7800X3D.
        A very good choice for silence + cooling.

        top for the moment

        as always the best advice and the best team at LDLC Aubagne!
        Replacement of an AIO following a faulty one.

        Done by the TAF for the moment, but this is just the beginning

        I changed my S.L. 2 for this S.L. 3 after the old one broke down after 3 1/2 years of use, despite the fact that I had replenished the fluid level and changed the thermal paste twice in recent years. White particles were forming in the liquid in the old one and I imagine this clogged the pump/circuit. It worked intermittently at the end.
        Apart from the breakdown, I was very satisfied with the system, so I decided to put my trust in Be Quiet! again for this new model. We'll see what happens over time. I probably won't get a third chance with their AIO cooling system if it breaks down again before 5 years (or if I change it myself).
        The cooling and noise levels are very good (like the previous model) despite the high temperatures, so I'm giving it 5 stars, but I'll come back and lower the rating (or post a new review) if another fault occurs.

        Beautiful beast ..

        To take the pressure off a Ryzen 9, if you have a tower that accepts this size of AIO, don't hesitate for a moment...

        Pafait for Ryzen 9 9950X3D

        Perfect for Ryzen 9 9950X3D. The proco heats up quite a bit and I wanted a big radiator with three fans to cool it down.
