It's not just temperature: many laptops also hit their power limits under full load.
I had a Surface Book 2 that was particularly bad for this, I think because it uses the same connector as older versions, and it could not supply enough power. Undervolting seemed to help quite a bit.

- XMPPwocky 6y agoAnnoyingly, there are 3 major related limits for Intel mobile CPUs- thermal, power (both an instantaneous, absolute max limit and a set of "okay you can use 25W for up to 5 seconds but then have to stop" limits), and current. Within that envelope, the CPU can boost up to its max turbo frequency when needed.
