Does Ryzen 5600X need water cooling?

Contributing Writer. I am assuming you mean with an AMD Ryzen 5 5600x? You do not ‘need’ a liquid cooler for that, but if you do, ensure it is at least a 240mm or larger AIO. There isn’t any sense in getting a single 120mm or 140mm AIO, and if you are overclocking, you’ll need radiator space for cooling.
