HP Laptop Fan Issues

[toro1]

I have a 17" HP laptop and shortly after getting it the fan started acting up. Sometimes it is on full, and sometimes it just cycles up and and down. When running full speed, there are not any high use processes running so it seems the fan is not running in response to use.

When I first turn it on in the morning most of the time it states the fan has issues and the computer will shut down in 15 seconds unless I hit return. This message comes up irrespective of whether I have it plugged in or not.

One thing I have noticed is if the computer sits in a cool room, the fan almost always come on full speed, but if its sitting in the sun, the fan does not come on when starting up. Not sure what temp sensor they use, but could it be wired/installed backwards?

In searching the web it seems this is a common problem on HPs, but there does not seem to be an identified fix.

The fan running is getting worse (on full more often) so it may be time for a new computer, but though I would ask the brain trust if anyone has dealt with and fixed something like this.

The computer is ~1.5 years old and is running windows 10 in case that makes any difference.

TIA for any and all help.

You can go to HP's website, and check their forums. Lots of knowledgeable people there to help.

I have replaced the fan in my Hp 17" quad-i7 3 times now. In my case it would eventually do what you describe and also make a bad grinding sound that was miserable.

What I do now is run one of these external fans on full speed so my internal fan never (or hardly ever) gets used at all. Yes it is a little louder but nothing like the grinding, quacking noise

My laptop is ~7yrs old at least. Replacing the fan requires a complete teardown which takes several hours, not pleaseant. But the laptop is still extremely fast and otherwise 100% dependable so I have committed to keeping it alive. I do keep spare fans on hand just in case.

You could try an app like CPU Speedfan to adjust the fan speed but I have found that most Hp have locked this control out. Also get CoreTemp to keep an eye on your cpu temps

we ran HP Spectre laptops of various sizes at work and saw this right away around a year ago and, AFAIK, there's no one solution.

It may depend upon the load/apps you are running. My laptop used for SW dev was "resolved" by updating the BIOS. Others who ran Altium had to drill extra vent holes into the bottom case.

You can see temps with HWMonitor: https://www.cpuid.com/downloads/hwmo...nitor_1.43.zip
I think temperature sensor in onboard the chip (not sure), so nothing you can do.

Could also be GPU if it separate.

I think this happen to me a few years back. It was either chrome or firefox. A simple uninstall and re-install fixed, the fan on full blast even though it did not take much CPU power.

There is always something wired running in the background. Few places to look and disable stuff:
System Configuration (or task manager in the startup tab)
Task Scheduler
Services

Could be anything, good luck!

What CPU does yours run? Intel? AMD Ryzen?

I have two laptops, one is a Intel i7-10850h, and even though it's Intel's topline CPU the thing runs quiet at idle, stays within 30c and fans run 800rpm. I also recently bought a AMD Ryzen 7. At idle, the thing was running 50+c and 1500rpm fans. After some research, the latest Ryzen 3000 and 5000 series run the CPU at 99% minimum which is ridiculous. AMD said it's designed that way and it's to boost the multi-cores quicker. If yours is a AMD Ryzen, do a Google search of AMD Ryzen idle and you'll see it talked about often. I simply went to power management and lowered the minimum CPU state down from the 99% and now I idle in the 30c and fans under 1k rpm.

*edit* doh me, I see you have a i7, as have been suggested, try cleaning the existing fans first and check the background processes to make sure no junk is being ran in the background when you're idling.

Thanks all for the suggestions and I'll start working through them, but to reiterate; most of the time when I start it up, the fan comes on full speed. It can sit all night off, but as soon as i hit the on switch in the morning, the fan comes on full speed. However, if I leave the computer in the sun and then turn it on, the fan doesn't come on.

After my earlier post, I remembered another symptom. Many times if the fan is cycling on and off and I apply pressure with my fingers on the bottom directly below the touch pad, the fan will take off full speed. It will then drop back down after I stop applying pressure. This makes me think I might have a cracked board/trace, but I couldn't reconcile that with immediate start up behavior.

Could a trace be bad and when the computer is cold the fan goes full on (trace open), but when it is warm the contact is remade?

As I said, I'll try a few things but this seems to be an odd one.

Get a can of compressed air and blow out the vents. Also look into getting a laptop stand that elevates it to allow more airflow on the bottom. With the newer high rate processors/video cards, tons of heat is being generated hence the fans auto starting. Over time the overheating will damage the computer.
