Hp pavilion a730n. fan turns on constantly, is there a way to check inside for dust or what else could the problem be. it doesnt seem to affect performance, it is just irritating.
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.

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.
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.
Your system is trying to run. If you can see on the screen what key(s) to get to setup, <del>, (F1), hit the key and get to setup. See what video card you are trying to go to first. Then check your boot order. Make sure your Battery which backs up this information is good. Is the date correct?
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.

You can get a can of compressed air and take off the CPU fan to clean off any accumulated dust on the fins.
