In my experience, EVGA RMAs return the same item if they can't find an issue within a few minutes of scripted testing, sometimes just visual inspection. This is more likely to happen if they don't have much stock of replacement devices. They certainly don't go out of their way to find a problem. Considering their engineering group didn't find the design flaw during engineering, I doubt the RMA testers are going to.
This is a design flaw. The paste they use is relatively high quality, fresh, and properly applied, more or less, so repasting may buy you only a couple degrees, not nearly enough to keep the CPU in line. The heat pipe they use is simply unable to shed the heat produced by this CPU. Once it gets up to full temp, the heat pipe fails to be a heat pipe - the fluid is unable to condense at the far end since the whole pipe is hot enough to boil the liquid inside. It's basically a pipe of uniform steam at that point, not particularly good at moving heat one direction. This is why the CPU temps fluctuate so rapidly even when fan boost is on. It can't produce a temperature gradient, the load is too great. The GPU is fine, it's a higher spec heat pipe and works as it should.
"This is the world's first true underclocking laptop". There, fixed their marketing.
I could underclock to 2.8, undervolt to -100mv, hope it's still stable, and still have a machine too hot to touch..
I'm cancelling my RMA and selling the laptop. What a waste of time.
