Yes, we do cover components in an event where the cooler leaks and damages your other hardware. We have a process in place to tackle these cases and they are handled on a case to case basis.
Now, in regards about the Aluminum/Copper being part of the loop, now that's a totally different ball game. Most leak cases that we have seen were caused by the tubes not being properly secured, and a few caused by the pump cover being loose. We have NEVER seen a leak issue where galvanic corrosion within the loop was the reason why the cooler leaked.
We’ve been selling completely sealed all in one coolers with copper coldplates and aluminum radiators for more than 5 years now, and all our coolers carry a 5 year warranty. While you’re right that corrosion can occur, we have yet to see it happen in the expected lifespan of the cooler due to the anti-corrosion coolant used. We stand fully behind our products and their warranty, and as the best selling all-in-one liquid cooling products in the world, if anyone were going to see a problem, it would be us. Our anti-corrossion coolant and sealed units have proven more than effective at reducing or eliminating the galvanic corrosion risk.
Going to a copper or brass radiator would add significant cost – making all-in-one liquid coolers significantly less affordable to users. The added performance is also not significant for the majority of users in the type of loops we’re currently offering. However, we may explore these options in the future. For right now, however, we are confident in our product quality and reliability and thousands of our customers would happily agree.
