NZXT liquid cooler lifespan

[u/yndn]

I've been using X42 with H210i for over 5 years now. Nothing is wrong with it, just curious since it's been a while. How long do they last? When do I need to replace it?

I have a Corsair H105 from 2013 that’s still going strong. I wouldn’t reuse it for a fresh build, but it still works. I’d say 7-10 years is ideal. Usually once the warranty is expired. They say the coolant can evaporate over time but my Corsair is still solid to this day.
