Intel Thermal daemon: Linux daemon used to prevent the overheating of platforms

Intel shall put their act together and build processors not heatears. What good is a laptop's 4 core processor when only one core is working and the other 3 are thermally throtled ?

I wholeheartedly agreed.

I would rather have four-core underpowered and underclocked than one that is running and other three CPUs that are cooling off.

Better yet, the entire CPU chipset regulates itself without consuming their own processing bandwidth.

CPUs do regulate themselves in hardware. They can throttle to whatever maximium Tdie is registered by the BIOS or sometimes the host system within milliseconds and even communicate with the VRM.

Apparently, you haven’t minimize the current and future need for an upower daemon, not even close.

CPU throttling means decreasing frequency (and voltage). By definition, CPUs will operate at their maximum possible performance given thermal limits, making your scenario impossible. The harsh performance degradation observed during prolonged compiles stems from the aggressive turbo limits Intel enforces, which draw far beyond what the CPU and VRM can sustain. For 15 W, 28 W, and 45 W class CPUs, the PL2 values are 55 W, 64 W and 115 W.

Now they just need a Maxwell's daemon to keep all the hot out of their processors! /silly
