How to prevent thinkbook 16 laptop from underclocking and staying at low temperature?

ie flag

Recently I have purchased Lenovo Thinkbook 16 G5+ IRH with Intel i7-13700H processor.

While I was stress testing CPU on AC, its frequency reached 4.0GHz for a short time and hit 90C, and then it underclocked to 2.5GHz at 60C with 25 watts power consumption for a long time.

Apparently 60C/25watts is not ideal and I expect it to stay at ~80C/55watts. I tried setting performance governor, changing BIOS setting to extreme performance, and ignoring BIOS PPC TPC limits with no luck. However, the scaling_max_freq parameter still shows 4800MHz.

I don't want to undervolt CPU and look forward to increasing temperature and power limit. Is there any chance that I can prevent CPU from underclocking and staying at low tempature?

Does the BIOS provide any overclocking options, as this is what "increasing temperature and power limit" means? If not, there isn't much to be done.

Have you tried rebooting and then running a thermal throttling daemon to prevent over-temperature? You might have become locked at lower CPU frequencies due to the high temperature event.

@mikewhatever Unfortunately, BIOS doesn’t provide any related options :(

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.
