Hi, I'm thinking on changing my cooler to an AIO, but i'm still kind of considering my choices here. Now, I heard that AIO do have a lifespan before everything inside gets dirty and gunked up. I'd like to know, on high gaming use, maybe like 8 hours a day, how long will the AIO last? And if the AIO gets dirty and gunked up, will it be covered by warranty? Also, if by any chance it leaks, and killed my other parts, will contacting the manufacturers (like corsair) gave me some sort of warranty of said killed parts? Oh, and one more, can you give me some recommendation for budget 120mm AIO with good warranty? Thanks.
