HP 15-AC115TU
Microsoft Windows 10 (64-bit)

I have a HP Laptop 

15-AC115TU

It was running fine but lately the fan spins out of control for no reason. IT's not even hot.

It starts spinning the very moment I open the lid and doesn't stop.

I have installed Linux on a separate partition, but it spins out of control on both Linux and Windows.

Here is what lm-sensors shows me on Linux

pch_wildcat_point-virtual-0
Adapter: Virtual device
temp1: +36.5°C

acpitz-virtual-0
Adapter: Virtual device
temp1: +27.8°C

coretemp-isa-0000
Adapter: ISA adapter
Package id 0: +39.0°C (high = +105.0°C, crit = +105.0°C)
Core 0: +38.0°C (high = +105.0°C, crit = +105.0°C)
Core 1: +39.0°C (high = +105.0°C, crit = +105.0°C)

CPU is only 39 and 40 .. so why is the fan spinning like crazy??


I had to replace the fan because it ruined the fan.

Several months later the second fan wore out, so I ordered another one.

Inside the laptop is pristine. There's no dust or anything anywhere.

I have looked in BIOS, there's nothing in there that I can find tat will allow me to control the fan.

I can't find any software on Windows or Linux that will help me to control the fan either.

I was able to install some software to see what temperature my CPU is, but it's not even hot.

I don't want to have to buy a new computer just because the fan is spinning like crazy for no reason.

I am happy with this laptop. It works fine -- except for the stupid fan spinning like mad.

If I DO buy another laptop, I am afraid to buy HP because I don't want to deal with this fan problem again. If I can find a solution to this problem, I will be happy to buy a HP again -- because otherwise, this computer has been great.

It seems that the last supplier I got the fan from had dodgy fans.

Because I just installed another fan (that took a month to arrive from China), and the laptop is now perfectly fine.

It was the fan itself. It was spinning from the moment I installed it.

@mrlen76,

 

Welcome to the HP Support Community!

 

I reviewed your post and I understand that the fan is spinning constantly and making a loud noise.

 

Don’t worry, I assure you I will try my best to get this sorted.

 

I recommend you update the BIOS and the chipset driver from the below link and check if it helps.

I have followed the steps to update the BIOS drivers. That has not helped.

I will run the system test now..
