What I found to be fascinating was the die size; 22nm!!
From my experience skul, that happens purely due to too much heat. Maybe not necessarily just the CPU, but the surrounding components as well.
A trick I found is to do the run with the pc near a open window on a relatively cool night. It's like cheating to make your rad stay cool but hey, it works. I'll admit that was how I got to 4.5GHz

. I did mention ambients tho haha
P.S. PPCs has the EK full MB block for $79.95. Both acetal and acrylic versions
