Laptop fan running all the time

Hello,
I have a client whose computer, seemingly out of the blue, fan started running all the time. I had her run MBAM, SAS and CCleaner. We rebooted and viola! that resolved the issue.

It's been about 3 weeks and it has started again. She did the above as I did but the fan continues to run.

Any ideas of my next step?
Thanks,
Magas

Have client boot the laptop just to the BIOS and let it sit there.    If it runs hot and fans stay on then you know it must be the hardware (i.e, heat and restricted airflow) and has nothing to do with windows or what it is running.

Put Process Explorer (Microsoft System Internals) install it and look at what is chewing up CPU. Look particularly for strange (alphanumeric) processes in the Explorer tree.

What is the Power setting of the laptop set to?  Some laptops will do so if you use the "High Power" setting. Try switching to "Balanced"

this is typically because the laptop is full of dust, hair, lint, etc, which lowers efficiency.  Remind client not to use laptop on top of bed, blankets, anything else that isn't a hard clean surface.     You can probably just visually inspect with flashlight and if you see dust sticking to the fan then you're going to have to open it up and clean it out.

(It is sexist, but also true, women tend to have more crud on the inside of the laptop, while men tend to have it on the outside).

I would first check the CPU utilization when the fan is running to determine what process has the highest CPU Utilization.
We have discovered that Google Chrome, Microsoft IE, and Edge (if it is Windows 10 system)  web browsers can jack up CPU utilization depending on what websites they  are at.

John - I am assuming you want me to run Autoruns...correct? Attached is the file.

Neilsr - Power settings are balanced - she had not made any changes to those.

Dlethe - Client reports her computer seems free of dust and lint...using it on a desk.

Glenn - Maybe I'm not looking in the right place but I did a ctrl/alt/del and under processes I found - 92 processes running CPU usage 25% and Physical Memory at 62%.

I hope this helps...this is definitely not my area of expertise.

Run Process Explorer as it is better for this than Autoruns. PE is from Microsoft. You need to determine what is chewing up CPU. It could be a virus especially if the machine is physically clean.

On a good machine, CPU should run <5% more than 95% of the time.

Thanks...she just got home and restarted her computer in BIOS...I will keep you posted.

Will run Process Explorer next.

Agree with dlethe.  The fact that the vents at the outside of the case appear clear does not mean that the internal fans are and heatsinks are clear.  It is not unusual to open up an apparently clean laptop and find that the heatsinks and fans are caked in dust and lint.

Side note:  Using canned air from the outside of the case generally has no effect (it can't remove lint because it's blowing from the upstream side of the plug), or It makes things worse by jamming the lint plug in hard.

I use a small vacuum to pull dirt out. Works vastly better.

The fan was still running high when booted into BIOS. Suggested she bring me her computer.
Thanks...I'll keep you posted or shall I close this session?

i suggest to reboot any pc on a regular basis - dayly, or weekly.
for cleaning a laptop, for most models you need to disassemble it nearly completely to do it properly
and if the cpu or gpu cooler has to be removed, don't forget to renew the heat paste
sometimes a bios update can help also

Thanks guys...I am closing since I can't get my client's computer for a while.

Cleaning out my husband's computer worked for his running fan and getting hot...don't know why I didn't think of that myself!

On a personal note .. You not only clean out your husband's computer, but have the skills and desire to do so??

Wow.   He's a lucky man.

Hey there nobus...always good to hear from you. Your assistance has always been valuable.

However noted...I'm already married. ;-)

Just having fun, we may now close this question.

I'll be back if I still have issues with her computer and with my inevitable next request for help!
