B4 the delid my 4770K ran at 65C at stock (under load), the furthest I could push my CPU was 4.3Ghz
After the delid I was able to run the CPU at 4.7Ghz while maintaining temps in the high 70S low 80S. Very happy with the result, if you have a 4770K and want a killer overclock I recommend the vice method for the delid
I ran the test again at stock (w/ the delid) and saw a 15-20C temp difference. B4 it was 65C, after the delid it maxed out at 47C
happy deliding
