How do I set fan speed to max in Ubuntu?

ae flag

My laptop tends to run really hot and I don't think Ubuntu is increasing the fan rpm enough to match the rising temperature. I have looked at a few fan speed related tutorials and they all go into installing lm_sensors. However, I don't wish to monitor the CPU temperature at all. I would instead like to set the fan speed to its maximum. How do I go about doing this?

Have you checked your firmware/BIOS settings?

Better to just try and solve the overheating problem. Do you have a Nvidia card? If so, what version driver? What version Ubuntu? How old is the laptop? There may be a lot of dust build-up inside that requires cleaning. The CPU thermal paste may require cleaning and re-application. Install lm_sensors to determine what the actual temps are.

@heynnema There's no dust for sure. I open the case and blast with compressed air about once a month. Its a macbook air. While in the macOS it runs really cool, like 28 or 29 degrees celsius. I'm using Ubuntu 20.04

Look at installing `thermald`. It has a custom configuration file that can be used maintain a certain max temp.

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.
