It only seems confusing because you took them out of context.
In case #1, I was arguing: don't buy a CPU without a roughly suitable cooling solution, or you might be wasting your money vs. a cheaper option.
In the second case, @thestryker
wanted a new CPU but is lamenting the high power limits. In that case I was saying what difference does it make if you set the power limits a little lower or if the manufacturer did it? No matter what, it sounds like he doesn't want a 65 W version or fewer cores, so it doesn't make sense for him to just buy a non-K or non-X model. The point is he doesn't want
all of the heat, even if he has to live with slightly lower performance.
Get it, now? Case #1 is about wanting not to waste money, while case #2 is about wanting not to waste power.
