When a AIO clogs up you toss it. When a Noctua C/D 14 clogs up, remove fan and suck out the clog with brush and vacuum cleaner. The fan should last 5 years or more. So the only thing that is left with a AIO is the fans. DIY water has got to be cleaned and drained if you use flexible tubing annually. Rigid maybe once every 3-5 years drained and cleaned. You still have to clean the dust out of the radiators 1 or 2 twice a year. They can both be moved to another socket style. I have had three different water cooler set ups and will not be using water again. A Noctua C or D 14 is almost as good as 240mm AIO and better than most if not all 120mm AIOs. If your ambient is 40C water is better, But 30C or less no real advantage. Truth I don't get any more DAILY Ghz out of a FX-8350 with water than I do with a C14
