New Kraken Elite V2 AIO's have problem
I have already made post on r/NZXT before about my 9800x3d overheating with almost new kraken elite v2 360mm aio. As some people suggested, i've replaced thermal paste, remounted cooler multiple times, put the fans and pump speed to 100%, nothing helped to solve issue with my 9800x3d hitting 95C! Finally i replaced it with different aio (8 years old master liquid 240mm) and no more 95c and overheating, 84C max under load now.
But it bothered me why almost new and expensive aio was not able to cool my cpu so i investigated little further and what i found was disgusting...
If you look closer there something growing inside the aio or whatever crap this is. Micro-fins are all full of it and restrict fluid flow so it makes sense why it wasn't able to cool anything.
It still won't explain why there is bacteria growing inside less than a year old aio? But it sure explains why there are a lot of complains about kraken elite v2, high temp and pump issues with these coolers.
