The technical translation of such a marketing claim typically goes like this:
Using the most howlingly strong fan available that will easily fit on to the device, the CPU in a 20C ambient room will be reaching the peak operational case temperature as rated by the CPU manufacturer.
Such temperature are typically measure by Tcase, being the temperature of the IHS atop the CPU die (the CPU die actually being quite a deal warmer than Tcase).
Always be wary of power dissipation limit figures. Such figures are given at the outer operating extremes of ALL the devices in the test system (CPU, temperature, fan, etc), but for some reason the natural human response is to fail to perceive such information for what it is.
The natural human response from me observing people's behavior online, is to think "Oh, so long as my CPU is dissipating less than 130W, then it won't get hot", which I guess exactly explains why such marketing information is given.
An analogous example would be to think of a car engine's peak power output. One rarely considers that and thinks "So long as I'm just below that figure, the car engine will be running quiet and cool", but for some reason this logic is switched off for many people when reading thermal dissipation figures.
