How to lower the critical temperature of the CPU, so thermal throttling starts earlier

is flag

I have an old Laptop with a broken heat sink, which leads the CPU to heat up to 80°C during small workloads, and briefly reaches 100°C during higher workloads (e.g. during system updates and compiling code). When running lm_sensors, i recently found out that the critical(as well as maximum) temperature of my CPU is set to 100°C, meaning thermal throttling is not really doing anything unless the temperature already reached the maximum allowed temperature.

Is there any way to lower the critical temperature so I can test if thermal throttling would keep temperatures lower while not slowing down anything too much? I know that this is a suboptimal solution at best, but I'd like to extend the lifespan of this laptop as long as possible.

Edit: The CPU is an Intel i7-6700HQ

What kind of CPU is in the notebook? If it’s an Intel Core-series, you may be able to do it …

I use [TLP](https://askubuntu.com/a/1309400/968501) on some old machines to manage CPU/GPU heating.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
