Fan runs loud,constant on HP a1620n

I had some startup problems about 2 weeks ago that seem to coincide with the fan problem. I took off the cover and fiddled with the hard drive connections and cleaned out some dust inside the case. The boot problem seems to be OK now, yet the fan problem persists.

Any ideas?

    I've cleaned the inside of the case thoroughly, including the fins on around the CPU and the problem persists. Any more ideas?

    Exact same problem on an HP a1030n. Have cleaned it out numerous times and fan continues to run loud and constant. Annoying bigtime. Need some better help than the first barely legible reply. Ideas?

Pavilion desktop m9040n the fan races intermittantly


These crank up when the system starts to get hot, when cooled down they resume running normal. Open the PC and vacuum out the dust, clean the filters it you have them on the fan intakes and outtakes. This will help.

Pavillion a1620y spontaneously restarts at various times. There is no clear pattern to the restarts.


Right click on 'Computer'.

Properties

Advanced Settings

Startup and Recovery

Untick the box 'automatically restart'.
This will give you time to read what the error message is when it does it again.

If it still restarts, your system is overheating. Check the fan is spinning inside above the processor.

If it isn't, simply replace the fan (unclips and uncouple a cable).

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.

Hp Pavilion a1620n seems completely dead. Went through a diagnostic and presumed the ps was burnt out. Have since seen the ps light on while all internal cables are unplugged. Can plug all cables in and ps...


No, it indicates a bad power supply.

1) ALL the lights use less than 1 Watt
2) EACH fan uses 2 to 3 Watts

3) A typical processor uses 55 to 125 WATTS.

The base model of the HP Pavilion a1620n Desktop PC, comes with an Intel Pentium D 925
(Operates at a maximum of 3.0GHz)

The Intel Pentium D 925 uses 95 Watts,

http://en.wikipedia.org/wiki/List_of_Intel_Pentium_D_microprocessors#.22Presler.22_.28dual_core.2C_65_nm.29

In most cases the inside of the computer is dirty, as well as the inside of the Power Supply, and it's fan.

Heat = Wasted Energy
When the Heatsinks inside a power supply, and it's Fan, (To include the fan blades, fan center hub, and surrounding fan cage), become clogged with gunk, the cooling capacity of the power supply drops tremendously.

Since Heat = Wasted Energy the power supply tries to keep up with the power load demands.
Eventually components inside the power supply fail.

(Usually the Electrolytic Capacitors are the first to go)

The power supply inside a Pavilion a1620n is a common SMPS. Switched Mode Power Supply.

http://en.wikipedia.org/wiki/Switched_mode_power_supply

The style is the common ATX, that is used in over 90 percent of desktop computers. (ATX 12V)

The Wattage is 300 Watts.

Should you like help in finding a replacement power supply that is affordable, and reliable, just state so in an additional comment.

I do advise staying away from the cheap generic models, as they can fail in 6 days to 6 months. ($20 to $25 range)

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.

I think the fan is making a super loud grinding noise.


I would not recommend this. You could fry your cpu and then you would have no notebook. If you are going to open the notebook make sure there is nothing interfering with the fan. The fan can be replace. Take the fan out and try to replace it, if needed. Do not run the notebook without a fan.

E-Machine T6216 PSU fan runs, computer will not boot


Giving the fact that your fan is constantly running and you had an electrical spike you should take it in to be looked at. If it overheats then the motherboard will go and it will cost more to fix it than to buy a new one.
