Or do - because water cooling can be a fun hobby. I've got a custom loop with my Ryzen system (420 + 280 rads, mostly EK kit including a D5 Glass XRes) and it's been enjoyable putting it together, and if you're not totally incompetent easy enough to make leak-free with the latest generation of fittings. As for a pump failing, as others have said the CPU will thermally throttle before damage is done, but for added peace of mind I'm running my setup with an Aquaero which will shut the computer down if the coolant temp breaches a set threshold, or it senses the pump has failed. The biggest thing for me is that my computer is EERILY quiet unless I'm pegging all 8 cores, and the GPU, at 100% ... which makes for a nice peaceful environment.
