> Consider that even with the most high end CPUs, they include the copper slug stock coolers than can make even a 45W rated CPU thermal throttle.

In one of the thermal design documents of their processors (It's either Core2Quad family or i7 3rd generation, I don't remember), it clearly states that:

"The included processor cooling solution is neither guaranteed nor designed to keep CPU within acceptable thermal envelope when the CPU is 100% utilized".

So they basically say that they include a complementary HSF assembly to smoke test your CPU until your proper HSF arrives.
