Precision 7550 & Precision 7750 owner's thread

[reise]

Hi everyone. I've read the topic, but I still need some advice. I have a DELL PRECISION 7750, and unfortunately, as is well known, it has inherent thermal issues. Even when just turned on at idle, it easily reaches 100°C. The heat sinks, fans, and thermal paste are in the same factory condition (as in fact, the 7750's CPU reached 100°C even when new). I could certainly install the best thermal compound available, but what would change? 5°C, maximum 10°C, and that would be insufficient, because it would still thermal throttle. In the BIOS/UEFI, no matter what option I change (SGX, SpeedSpep, C-State, Speed Shift or Thermal Management), I get no resolutions, but only unacceptable compromises. For example, with Thermal Management in Cool, the frequencies are limited to around 3GHz in multicore, so it doesn't go into thermal throttling (or almost), but with very reduced performance. What can I do to defeat the monstrous temperatures of CometLake-H?
