Hey there Ohio,

There are a few things that cause a normally silent fan to get noisy.

  • Dust building up - Unlikely, but check. Clean if necessary.
  • Some internal wiring brushing against the trailing edge of the fan blades - Likely only if the case was recently opened. Re-open and check, relocate the wiring if necessary.
  • The fan is getting ready to fail - Most likely. Replace the fan. If you have an unused computer, pull a fan out of that one to use. New fans are available for under $20.00 USD .

This replacement is very easy.
  1. Four screws out
  2. Unplug
  3. Remove old fan, put new one in.
  4. Plug in
  5. Four screws in
Don't wait until it fails, though. A cool computer is a happy computer.

Hope this helps,
Mike

Change the fan, it's probably the blades rubbing somewhere or the bearings are noisy. PC World sell spares and fans are very cheap to buy.

Blinking blue light and loud fan


When does the "blinking blue light" appear? As far as the loud fan is concerned, it is possible that your computer has dust built-up inside the case. Open it and try to clean it (GENTLY) with a blower, or a can of compressed air (do NOT use a vacuum cleaner). Specially clean the fan in the middle of the case.

My gateway ZX4351 is too loud.. How do I open the case and clean the fans?


Depends if the fan's can even be cleaned. There will probably be several screws you will need to remove on the back, along with the stand. The edges may need to be pried open, preferably with a plastic pry bar so you don't damage the case. Once the case is open unscrew the fan and see if it has a rubber stopper in the center, possibly under a sticker. If it does then you can open that and add a drop or two of sewing machine oil and it should be quiet after. If it isn't then I'd just replace the fan.

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.

My fan on my desktop computer is so loud, it just


Open the case and clean the dust and debris out around the fan.  Also check to see if fan is hitting any wires or plastic plugs and tape them out of the way.  Apply a little REM oil or silicone spray to the spindle.  Then put the case back on and give that a try old chap.  Still no luck?  Then your fu.k.d and need a new fan.
Cheers.

The fan in modem makes loud noises at times


Modems don't have fans.
I think you mean your fan in the computer makes a loud noise. Some computers have settings where the fan speeds up if you are doing a lot of things--making the computer work harder.
Some fans make noise just before they fail. Depends on the type of noise. If it's a sound that has a lot of rattling in it or maybe a high screeching sound, I'm thinking you'll be needing a new fan. Probably a CPU fan is the culprit. Also, fans on video cards often go bad--so you'll have to open the case and listen to where the sound comes from.

Fan is loud


well if its not attached to the motherboard in any place, for example the heat sync, or the cpu, then you can remove the fan, any other place, you shouldnt replace it because the mother board sets the fan at a certain rpm, and which would sound loud with any fan. I know this because i replaced the fan on my sony computer, and on a generic motherboard, and it was quiet, but when i put it on my sony computer, it was loud, so if you want to replace your fan, i suggest liquid cooling, it is completely quiet, and keeps your cpu much cooler than a fan. Best of luck.

My computer makes a loud noise in the fan


The drive door issue may indicate a virus infection. As to the fan, you would have it replaced. If not under warranty open the case and track which fan the noise is coming from

When I turn on my emachine computer, I now get a louder whirring noise. Is this dirt accumulation on the hard drive fan?


Well there is no fan on the actual Harddive Fans, Unless you mean the PC Case fans, in which dust built up on it wouldn't make a loud whirring noise. If it is, it's because the fan's ballbearings are bad and you need to replace it.
The harddrive is a Small rectangular silver or black box on the inside of the case towards the front. If the loud noises have started coming from there then the Harddrive is going bad, and you might want to back up your data immediatly.

Post any comments for further help, hope this answers your question. Feel free to leave positive feedback, and thank you for stopping by Fixya!

Loud noise


Typical problem in most computers, the fan is experiencing a "burn out." This means there is either something caught in the fan causing it to create noise, or the motor is going bad. there are two fixes for this problem.
1) open you computer's case according to its manual and remove the system cooling fan and give it a thorough cleaning.
2) you may need to replace the cooling fan with its recommended replacement model.

Hope this helps!
