The mobile CPU began acting oddly, reaching PROCOHOT at 70° instead of the usual 95° threshold. Occasionally it works fine, but around 60% of the time it throttles to 70°. I can't adjust an offset in the throttle stop settings because that would cause random shifts between 70° and 95° limits. Disabling BD-PROCOHOT didn't resolve the problem either. After installing OEM drivers and various Intel management tools, nothing helped. Switching OS from 21H2 to Windows 11 and then back to the latest stable Windows 10 didn’t improve things. A temporary fix seems to be setting an offset for PROCOHOT and removing it several times, but the throttling returns when workload changes. It's a frustrating situation. Do you know any possible causes or solutions?

Which laptop are you using? Lenovo seems to be misrepresenting their product by understating the thermal throttling limits. In the ThrottleStop Options, adjust PROCHOT Offset to 5 and then choose Lock PROCHOT Offset. This is the only method to stop other programs from interfering with this setting. The default Intel offset is 0; changing it to 3 or 5 makes sense. Companies that suggest a 30°C offset are taking unnecessary risks. PROCHOT and BD PROCHOT are distinct concepts. Are you employing any manufacturer power management tools? The quiet and cool mode can lower the thermal throttling temperature, which may mislead users into thinking their device is operating smoothly. This reduces performance and makes the laptop uncomfortable to use.

It's an HP device. Another Windows reinstallation seemed to make a difference for the first time. I noted I had reinstalled the OS three times. The first was Windows 10 21H2, an insider preview version, so problems were anticipated. The second was an upgrade to Windows 11, another preview release. The third happened when I mistakenly installed a modified, altered version of Windows 20H1 inside Windows 11 without any changes, which caused memory leaks and odd throttling. After cleaning the entire drive and starting fresh with a clean original copy of 21H1, I no longer experience thermal throttling. However, something else occurred: the CPU changed its PL1 setting to 10W from 17W and kept it steady, while PL2 stayed at 35W without change. From what I understand, if the laptop was running very hot (below 70°C), PL1 wouldn't drop below 15W, suggesting a thermal ceiling rather than a throttle limit. Software monitoring tools didn't flag any thermal throttling issues, unlike before.
