Feels like CPU manufacturers should be at least slapping a big warning on if they're selling a CPU that draws more power than any available cooler can dissipate.

In hindsight, I would have gone for an AMD deskop replacement laptop instead of the Dell Intel-based gaming laptop that I purchased last year. The CPU is the best the Raptor Lake line has to offer in mobile format (i7-13900hx) but there is no conceivable way for the laptop, ast thick as it is, to cool it beyond very bursty workloads.

This affects the laptop with other issues, like severe thermal throttling both in CPU and GPU.

A utility like throttlestop allows me to place maximums on power usage so I don't hit the tjMax during regular use. That is around 65-70W for the CPU - which can burst to 200+W in its allowed "Performance" mode. Absolutely nuts.

The idea is that it's for a limited time, after a period of lower-than-that cooling. In other words TDP is time-weighted.
