All product specs are lies. The CPU cooler in this computer claims it

The TDP figures given by Intel and AMD may be given in "Watts" but they
don't correspond to actual watts of power consumed by the processor,
they're calculated mumbo-jumbo, then the cooler manufacturers base their
recommendations on the CPU manufacturer numbers, so it's lies all the
way down ...

How hard can it be to quote the TDP as the amount of power the CPU uses
(which is the same as the amount of heat it gives off)?

It is used for engineering as well as public relations purposes.

What part of engineering requires a number that is meaningless to be stated? It's neither the heat given off or the power used.

The coolers are "honest" in that their theta can be
verified by FrostyTech and they'd look bad if they
fudged the number.

What is happening today, is "industrialized overclocking".

Are you saying the TDP of my Ryzen is actually 105W if I forbid it to up the clock? That's like selling a car that will go 100mph and only make a noise of 50dB. But not telling you that you can't do both at once. Actually I've seen that kind of bull****, I bought an HP (spit!) laser printer which quoted pages per minute. It was referred to (hidden away in the smallprint) as "blank page speed". If you printed blank pages, it would achieve that speed. But a full page of text (what most people print) was nowhere near as fast. What they'd done is tell you how fast it could spin the roller.
