Hi, I have an NZXT water cooler in my machine, and my i7 8700k is oc'd to 5.2 GHz, but when it is stressed it gets over 90C, which as far as I know is way higher than it should be, as its water cooled. When I lowered it to its turbo (4.7 GHz) its stressed temps dropped to 85C, which as far as I know is still warm. It idles at 45C as well, I'm not sure if that is normal or not.
