There are 2 fans at least on the inside. One is for the CPU and the other is for the power supply. They are supposed to run continuously to keep the heat from building up inside the case. (Heat is what is worst for your CPU.) It sounds like the noise itself is what is disturbing you. Unfortunately, there isn't much that can be done for the sound level created by the fans. My wife subscribes to the theory of turning up the music a little louder to drown out the noise of my graphics card fan. The only cure would be to invest in a lower noise fan- you'll see decibel ratings on some of them.
You can get a can of compressed air and take off the CPU fan to clean off any accumulated dust on the fins.
If you find this solution helpful, please rate it accordingly.

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.

your CPU might be getting hot making you computers fan to run consistently

Can you change the fan speed on an hp pavilion 504n?


you can research the actual manufacturer of the motherboard that HP uses and see if they offer a software progrm that controls such features as the fan speed. its highly possible they do.

My a730n computer will not turn on. The green light flashes in the back. Local frys tested power supply and said it was working. Fans dont come on...nothing?


it could be a mother board problem or Power supply issue. Even if the power supply works it wont supply required voltage to some components.Its better you get a new power supply and test it.Still its not working it could be a mother board issue.There will be a chance for power button issue also.

Fan runs constantly


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.

Hp Pavilion a730n unknown issue


You might want to check the CPU fan for dust and re-seat the RAM. I sounds more like a heat issue.

Power Supply


is there a problem you are encountering? does your pc shutting down? what is your present power supply wattage? if that is 300watts then you can change even 450watts.
