8700K on a NH-D15

Hi guys,

Any expectations or real world tests of what a NH D15 can do on a 8700K? What's the expected overclock? Could it handle an all core 4.7GHz?

Unless you have the absolute worst IHS contact possible, 4.7 GHz all cores should be very easy. If your IHS contact happens to be terrible, no ambient cooler - including custom watercooling setups - is going to fix the thermal bottleneck between the die and IHS.

For reference, I have an i7-7820X at 4.8 GHz running on an NH-D15S. The CPU alone can pull up to 275W. There's no way you're going to get an i7-8700K to pull nearly as much power or dump nearly as much heat, so you should be fine. I would, however, consider delidding or purchasing a delidded CPU. There is always a nonzero chance you get absolutely awful IHS contact.

I didn't spend a lot of time messing with it before delidding, but I had no issues at 5.1 in realbench with my nh-d15. I think it hit 83c at 1.35 vcore. The vcore was higher than needed but I just wanted a quick baseline before delidding, and delidding did drop temps around 15c.
