    I believe it is the main CPU fan. Just within the last few weeks it now runs all the time.

One reason that a CPU fan may be running constantly is that it may not be able to cool the cpu down. usually this could be due to dust or debri clogging the incoming or outgoing vents or even dust accumulated on the fan itself or the heatsink.

My cooling fan on my HP Pavilion 23 touch screen desktop has the cooling fan running constantly now? Why would this happen all of a sudden?


It's possible that either the chip it's cooling is running hot. The heat sink inside may be covered with dust preventing the chip from being cooled. It also might be dust on the fins of the fan itself causing the extra noise.

You should have it checked out and cleaned to prevent possible damage and fan failure.

Fan runs constantly on hp pavilion a1530n


WARNING: Before you start troubleshooting remember that you are dealing with electricity that can KILL.

First clean your computer of dust you could use a fine air blower from a compressor or a can of compressed air whatever you use make absolutely sure there is no moisture in the airlines


if the fan in your computer is constantly running to cool down the cpu and it is normal for it to increase it's speed, your fan should run quietly even it increases the rpm.


But if you hear a loud noise in the fan, i think there's something wrong with it.


I suggest for you to check the fan if it's coming in contact with anything. If the fan is visible while your computer is operating, you can observe it to know what is really happening.


I don't know what type of fan hp uses on their computers, maybe something is loose already on the fan so better check it or bring it to an hp service center.

My computer runs constantly its loud and annoying


I assume you mean the cooling fan on the CPU, this model uses a smart fan technology, it is meant to spin up faster to provide cooling. If is is doing tis constantly, it means the CPU is not getting adequate cooling (overheating), to check this, remove the side panel, clean all the dust and debris build up from the cooling fan and see if that helps

Desktop computer fan runs constantly


Hi,

Desktop fans do run constantly, you cannot avoid this.

The reason they get loud is because there will be a build up of dust on the fan blades.

To rectify this problem turn off the computer and remove the power cord from the rear. Then you need to remove the side panel from the base unit to expose the motherboard.

You will see that inside the case it is full of dust. Look at the CPU fan (the fan on the motherboard) also take notice of any case fans too, they are at the back.

To clean the fans and the case you can use a clean dry paintbrush or compressed air.

Once the inside of the case is cleaned you will see a noticeable drop in noise.


Regards.
