There was a point where pretty much all of the manufacturers would let you push your hardaware to destruction. Especially GPUs. However, I remember speaking to BFG before they went out of business (it was literally days before they closed their doors) and they were telling me that the 200 series Nvidia GPUs were their worst ever. They had thousands of returns, and no product to replace it with (because Nvidia ended production).
BFG went down because of this and because of their amazing warranty. I would imagine Nvidia and indeed others learned a lot from that, because now they lock the voltage and there is absolutely no way around it.
I mentioned this before, and it did have some sense to it. Intel could well be using TIM to make their chips run at higher temps preventing people from pushing them to destruction. Sandy was soldered, and with Sandy they offered a tuner's guarantee where you paid like £15 and they would replace your CPU no matter how you popped it. Yeah see, I don't think they do that any more.
I've also still got this nag in the back of my brain telling me that Ryzen are artificially locked at 4ghz. Doesn't any more find it really strange that no one has managed to get more than that on a consistent basis? I could be wrong on the AMD part of course, it may just be bad luck.
However, yeah, going back to the point I think that hardware manus hate dealing with RMA. It's basically giving away free product. GPUs hardly ever fail now, unless of course some one breaks it fitting a water block or modding etc. I rarely see friends having to send hardware back.
Intel are not a dumb ass outfit. They know what they are doing, and they are doing it for a reason.
