I can't find the video, but I watched it yesterday, where a guy with a 4770k with an h100i was at 4.3ghz at 1.295v, but was running at 90-95c and he tried reapplying sever different thermal pastes. He ended up delidding the cpu, applying new thermal paste under the heatspreader, and at the end with the same settings was at 70-75c. Not that I recommend it because it is really easy to screw up, and can kill a cpu and the warranty, but worked well for him.
