CPU overloads with fans running high speed when laptop is plugged in to the power

vg flag

I have a MONSTER TULPAR T7 V20.5 laptop(a foreign brand). I have Ubuntu 23.04 installed with the kernel version of 6.2.0-20-generic x86_64.

The problem is CPU overload when the laptop is plugged into the power. The fans run so fast even if I don't do anything crazy. I have the Nvidia drivers installed. When I unplug the laptop and use it on battery, the CPU overloading problem goes away, fans working silently and all these things happen under the same power settings. Both plugged and unplugged(on-battery), the power settings are balanced and on-demand for Nvidia. I searched a lot about the problem. However, most solutions were for specific laptop brand.

I tried installing lm-sensors, however it was unable to detect my fans.

what is using the CPU when you use `top`?

@rtaft When Chrome is open, it is usually at the top causing overload. However, it's not about that. Even when I just open IntelliJ and run a simple Java program, the fans go crazy. The problem only happens when laptop is plugged into the power.

Your battery overheats when charging Physically check your fan (rotating?, dusty?, unblocked?). Physically check for dust coating the chips/heat sinks inside your computer. Remove dust __carefully__ (no water, no power, don't knock connectors loose, check manufacturer's web site). Dust is a very good insulator, and keeps the heat inside the chip.

I finally found the solution. My laptop brand supports the Linux control center that was made by a company called Tuxedo. I installed that and finally, I am able to change the settings to Cool and breezy for fans.

Tuxedo Control Center

I followed the alternative way that was listed there.

and after that, run:

sudo apt install tuxedo-control-center
I sit in a Tesla and translated this thread with Ai:

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.
