I hope you're doing well. I’m Priyanka from the Dell Social Media team.
I understand you are facing fan and CPU temperature issues with your system. Please be assured, I’ll look into this and help you with a satisfactory resolution at the earliest.
As you are working with Ubuntu 22.04 and the system is shipped is originally shipped with Windows 11 Home on the system, So our support will be limited to Dell shipped operating system.
Thank you! We have received the required details. We will work towards a resolution. In the meantime, you may also receive assistance or suggestions from the community members.
areyo, given that your Dell Precision 7680 is a recent design whose inaugural support for Ubuntu commenced with the current Long Term Support release, Ubuntu 22.04 LTS, there's bound to be some early teething problems until the '7680's firmware and drivers develop further.
Thus, here's a couple of things to try in taming your computer's temps:
- Go into the UEFI setup utility and disable Intel's Turbo Boost. (This worked in resolving my Precision 5540's excessive temperatures.)
Prior to this next one, create a system snapshot via Timeshift.
We have purchased one of these units and it is running Windows 10. It has the same exact problem with the unit running with a very hot surface temperature. This was experienced without even running any applications. It was just logged in and sitting idle. The power settings are set to cool which is supposed to run the processor slower for better cooling, but it gets very very hot. The bottom of the unit is metal and that part is where most of the heat is. There are no obstructions to the vents on the unit, either on the bottom or the vents in the front.
I have just purchased a Dell Precision 7680 with Windows 11 Pro. It runs very hot, and I haven't even done any serious work with it, just setting it up and installing software. It even runs hot when idle. It's on a flat wooden desk and the desk top under it becomes hot. I notice it particularly because the mousepad becomes hot to touch!
I haven't done any tests but I get the feeling the battery life isn't the greatest either, but that's another topic.
Consumer demand for ever-thinner notebook computers sporting ever-more powerful SoCs is largely to blame for this issue. As gaming laptops show, a big case and larger fans are needed to tame temps effectively on a more powerful notebook.
"The main driver of increased thermal output in modern computing is the concurrent usage of CPUs and GPUs, which together generate a level of heat that’s difficult to dissipate in ever-shrinking chassis."
As fans of tools, not toys computers understand, an over-heating PC is a malfunctioning PC whose unchecked excessive heat increases the prospect of system destabilization and accelerated component wear.
A glorified, automated over-clocking technology by any other name:
"Intel® Turbo Boost Technology 2.01 accelerates processor and graphics performance for peak loads, automatically allowing processor cores to run faster than the rated operating frequency if they’re operating below power, current, and temperature specification limits. Whether the processor enters into Intel® Turbo Boost Technology 2.0 and the amount of time the processor spends in that state depends on the workload and operating environment."

The OS the Dell Precision 7680 shipped with is secondary to the operating systems it officially supports — which include Ubuntu 22.04 LTS.

When someone buys a name brand product, they expect it to live up to its claims as a matter of reputation and market share.

- Try the latest, stable kernel:
Index of /~kernel-ppa/mainline
https://kernel.ubuntu.com/%7Ekernel-ppa/mainline/
- Download the kernel segments into the same folder
- Checksum each kernel segment
- Open a Terminal from within the folder in question and then run:
sudo dpkg -i *.deb

Try turning off Turbo Boost in your notebook's UEFI then rebooting.
IME: Turn off Turbo Boost when using a Precision 5540 with one of Intel's more powerful SoCs (I7, Xeon or i9).
A tacit and understated admission by Dell that Intel's Turbo Boost causes processor over-heating problems in thinner notebooks.
