I actually went back and checked the power settings on my computer. I changed it from best to recommended and the fan issue seems to have been resolved. You might want to try that first.

New laptop, constantly running fan, high core temp? | Windows 11 Forum
January 28, 2026 - Both my and my wifes laptops (Lenovo) started running hotter with 25H2. I had to get a fan tray for my wifes to sit on. Meaning maybe you’ll still experience hotter temps? I can’t tell you for sure. Stuff you’ll most likely see on the net if looking: Click to expand... Thanks for those replies. I should have also included in my post: the laptop has done this from new so not a dust issue. I also did my own clean install of windows 11 on its own partition so no junkware, not even a lot of the Dell stuff including power manager.

Answer (1 of 5): Because you installed an odd numbered Windows, and one that’s less than two years old. Those are two grave errors. You should have known better. It’s entirely your fault.

I am setting up a new Dell Precision 7780, Windows 11 (23H2), and the fan runs constantly. As soon as the laptop powers on, the fan starts. I’ve installed all of the updates and drivers, and I’ve set the power plan to balanced. I even turned off TurboBoost in the BIOS, and tried setting the fan to Optimized and then Quiet. The fan still runs.

What is causing this, and is there a Windows or third-party utility that can control the fan settings?

Thank you!

One of the things I would try is to reset all BIOS settings.
Secondly, it is possible that the fan is either incorrectly connected (e.g. maybe the wire that reads fan speed is not properly secured - they usually have + - and RPM sense).
Third, it could be that the CPU is overheating. Either because the heatsink is not applied properly, or the thermal paste is not correctly distributed on the heatsink.

In our enviroment, we also very rarely order i7’s for laptops (not sure if yours is) for this very reason. The thermal management for most laptops does not help the performance; in fact thermal throttling can make a higher-spec’d laptop perform worse from our experience. If you need the type of performance a large multi-core CPU offers, a desktop or server instance is likely a better vehicle, while simply using a laptop to connect.

Because it is a new Dell, if resetting the BIOS to factory default does not correct the problem, I would open a case with them and go through troubleshooting. If it is either a fan connection or thermal paste situation, a tech will likely be sent to investigate, or they will likely send you a new laptop and ask you to send that one back for testing.

I’d be interested to know the outcome if you are willing to share.

Good luck, and hopefully something I have here will help out in some way.

Laptop fan runs high continuously...is this ok? :: Hardware and Operating Systems
You can't adjust fan curvres on a laptop. Least non that I know of. If the ambient increase causes the running temp to increase enough. Even just by a few degrees it could be hitting a temp that triggers fans to run at maximum rpm. A software update, windows or other, won't be causing a hardware change.

r/Windows11 on Reddit: Installed 23H2 and the FAN turns on everytime!!
November 1, 2023 - Just had a similar issue with the Windows 11 Canary Build 25987. For me, the fans of my laptop were at 5000 RPM regardless of what the load and temps were, but I had no "on and off" issues thankfully. Manually lowering the fan speed to a silent preset with an external program did the job, but automatic mode seems to kick it to a constant 5000 RPM for some reason.
