I thought they meant the overall lifespan of the product, considering that AIOs themselves have a reputation for failing sooner than just a pair of fans.
I have a 2080ti with an AIO and I love it. Temperatures never go above 64c at 99% usage. It does have a larger radiator (it has 2x 140mm fans). I can definitely recommend this type of GPU. Some people have complained that AIO cooled components have chances of leaking, but I've had AIOs for the CPU and GPU for a few years now and I never had this problem. I imagine it's just bad RNG for some :) It does not limit its lifespan since it has great temperatures.
Would the fact this is liquid cooled with an AIO limit its lifespan compared to a typical air cooled card? Would appreciate some opinions as I've never used an AIO solution before.
Just noticed that it has already been posted. My apologies :)
