G15 Ryzen, fan started running constantly

Question

I have a Dell G15 Ryzen Edition, running Windows 11. A few days ago the fan started running constantly whenever the laptop is on. I have run several virus scans, quick and full scan. I have checked for and done updates through Support Assist and Windows update every day since it started. I ran the short and long hardware scans through Support Assist. The short said all systems passed, the long did indicate a Video Card Primary Surface: D0809 - Internal Error (I did find a forum via Dell from about a year ago with several people running that scan and getting all systems fine except for that error and at that time the comments indicated Dell didn't know what it was). I have checked diagnostics through device manager and 2 different areas showed that my video cards were working properly. I have tried using canned air to clean out the vents and also started using a cooling pad. Task manager shows total CPU usage at 30% or less. I am beyond my scope of understanding for my computer (thanks to Google helping me find how to do some of the diagnostics). Any suggestions that I haven't tried?  Thanks!

It requires some system disassembly.  If you've never done the work before, find a reputable local repair shop -- it should be no more than what an hour's labor costs wherever you're located.

Go HERE and insert the private Service Tag number to check the warranty status.

* Plug the provided AC power adapter into the Laptop
* Restart the Laptop and tap F2 to enter BIOS setup
* Does the fan run constantly while in the BIOS?

If the system has never had internal maintenance -- and internal cleaning (not just an external run of a duster) and replacement of the thermal pads, it's long overdue for that.

This system is 4+ years old and likely needs maintenance.

@DELL-ChrisM2​ My warranty expired a couple years ago. I just checked in BIOS and the fan was running there.

@ejn63​ I guess that's probably what it needs. Is this something I do myself or do I have to take it a repair shop?

Well you laptop fan need maintenance

Well, according to your description, it looks like a thermal sensor or power profile issue. Have you tried setting thermal management to Quiet or Cool mode to manually limit fan aggression.

AngieDawn · Answer

@Rashmik​ I have not. How do I do that?

As already suggested call around for an affordable estimate. Someone who guarantees their work. Preferably a Dell-qualified store.
