I decided to try and up my overclock on my 7700k and bought a Noctua NH-D15. I've been trying to OC beyond the 4.6Ghz pre-set on my motherboard. I upped it to the 4.8Ghz pre-set and it seems stable but my temperatures are very high. I ran RealBench 15-minute stress test and at least one core will jump to 100C quite often and hold for 20-30 seconds before returning to mid-80s. My frequencies will also start to go all over the place (4.1, 4.2, 4.5, 4.6GHz for each core instead of holding 4.8GHz at 100% load) The other 3 cores will usually stay 75-85C. When gaming it will often spike to 95C+ and drop back to mid-70s. Most posts I read say that 4.8GHz should be easy with a NH-D15 and top out around 75C under load. I know delidding would give a significant temperature drop but I'm not sure I want to risk that. I set the BIOS back to the 4.6 pre-set and upped the fan speeds for the case to 100% but it still seems very hot. Did I lose the silicon lottery or does this sound off?
In case it matters, motherboard is a Gigabyte Aorus Z270 Gaming K5. I also have already re-applied thermal paste (large grain of rice CPU) and the previous paste looked like it covered the entire chip.
