Doesn't look especially abnormal for an intact 3770k, depending on ambients.

Distance to TJmax wouldn't change, and that's all that's relevant.

I only have a 3570k and it's only using 1.26 V at 4.6 GHz instead of OP's 1.28 V. But I use a simple True Spirit 120 which should be a lot weaker than the NH-D14. With the small FFT test in prime95, I see 10 C lower temperature compared to OP. It's staying below 75 C on the hottest core. That's at about 20 C (68 F) room temperature. I also don't remember it ever being high 70s temperatures when running prime95 blend for hours.
As mentioned 3570k generally put out less heat because they lack hyperthreading and thus cannot typically do as much work. Your ambients may well be lower than the OPs, and/or you could have a less leaky part.
Without de-lidding, it's rare for the cooler to be the weakest link on an Ivy. If you can't get the heat out of the die efficiently, it doesn't matter much what's attached to the top of the IHS. There is literally a ~10C difference between a 25 dollar air cooler and a 300 dollar custom loop on many Ivy setups.
