My Corsair H110 AIO have multiple corroded holes on the radiator channel after just 5 years usage. I'm so lucky the liquid isn't spill to my hardware.

In conclusion i will never go back to AIO especially those with copper block and aluminium radiator as this combi is prone galvanic corrosion.

Anyway, just change mine to EKWB P280 custom loop starter kit. Won't consider air cooler as well since all the surrouding components that in the air path will be very dusty after some usage period.
