Excellent cooling. Can handle the i9 9900k really well. The pump is a bit louder but as long as you have it on balanced it should be fine. ( Don't use quiet for the pump)
I kept it, as over time it became a bit quieter. Also I found a discussion on an official Corsair forum and an employee from Corsair said that the noise is within normal levels (somebody had linked a YouTube video showing the noise of the pump)
