Review on Fractal Design Celsius S24: Silent Liquid CPU Cooler - PWM - Intelligent 💧 Controls - 240mm Radiator - Includes 2x Dynamic X2 PWM GP-12 Fans - Black by Eric Young

These are great for cooling your system. You can choose between two modes: Auto = slower but quieter and PWM = louder but faster (means better cooling). This can be a good thing if you don't want to tweak fan settings and everything, but can also be a disadvantage if you want to tune your fan speed to hit specific temperatures without blowing your fans faster than necessary, resulting in more hands. free pc configuration. I overclocked my 8700k to 4.9 with no issues. They're generally very quiet compared to some like the H100i (which I also use in a different setup).
