AIO buildup using different metals. Ticking Timebombs

You might go as far as calling it planned obsolescence.

As zanza said, avoid asetek. They're the ODM for 90% of brand name AIOs. They only use alu, and they're huge cs. As he mentioned, some custom parts manufacturers like swiftech or ek also have some sort-of-all-in-one kits that, while more expensive, are more reliable and will perform much better over their lifetime, compared to cheap AIOs that might do well in the beginning, show good performance in reviews, and get progressively much worse.

AIOs with copper radiators do exist though, you just have to look for them. Alphacool provides units with copper rads to some manufacturers, but you'll have to double check each model. Be quiet uses them for their silent loop series, Fractal Design for their Kelvin series, and I'm sure more exist.

I hate that planned obsolescence It just kills me but it the way of the world, no company wants to kill return biz....
So the customer suffers, planned obsolescence is probably an American invention...

But i also agree about base buildup, but i never really thought about the Radiator...
So i found the video i saw and also another one showing the base...

I also think it would be a good idea to come up with a purchase list of real "All Copper" AIO's it would be an interesting exercise.

Enjoy

Well, it looks like propylene glycol + anticorrosives are more effective than I thought, and that corsair unit showed no signs of corrosion after years.

That said, it's hard to make 100% sure a specific unit uses a safe coolant mix, and I would still steer away from asetek-made units for other reasons. All-copper loops should perform better anyway: the radiator is better and they can use water, which is a better coolant. Well worth the price premium.

That was essentially NOS. You only get the corrosion if you have heat and mixed metals. The other problem with AIO is that they tend to have evaporation through the tubes, but you cannot refill it.
