As do I.
Meanwhile in a server, I'm starting to worry that as I work to flush performance issues out of the system, especially latency problems, that I won't see the sort of perf numbers I'm expecting because the fact that the machines are running well below 50% CPU utilization are likely to dogleg the moment it hits the thermal limits, and I have no way to predict that, short of maybe collecting CPU temperature telemetry. Not only might my changes not translate into 1:1 or even 1.2:1 gains, they might be zero gains and or just raise the CPU utilization.
Magical CPU utilization also takes away one of the useful metrics for autoscaling servers. Thermal throttling opens the door to outsized fishtailing scenarios.
