Instead of cleaning it by taking it apart,
try to clean it without taking the cover out.{hassle free}

tools needed:
2 cottonbuds
1 powerful blower{hair blower will do}
1 alcohol/water{used if the dirt is hardly stick in the spindle}

hold 1cottonbud and place it between the spindle{to make spindle not to spin while cleaning}
take the other cottonbud and poke the dirt out of the spindle one by one
then use blower to blow and clean the dirt out of the fan
dip cottonbud to the alcohol solution and use it to clean the hardly poke dirt
then blow dry your fan

Processor fan noise problem

1. You can can change fan
2. Open CPU cover remove the fan and clean it and re install it
3. After cleaning put only a single drop of lubricant under the sticker of fan wehre bearing area.

remember do not start your cpu when you have taken off the fan. and if you are not a technical guy call service engineer to do this.

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.

How do I replace Gateway dx4831 fan?

The plastic snoot is probably just clipped on to the fan casing which is usually screwed to the heat sink. You could probably just remove the snoot
which will allow you to see what you need to do to remove the fan. The fan can normally be cleaned and a light grease applied to the spindle.
All you have to do is remove the fan, look underneath the fan and there should be a round label with things like the voltage, current, and make of the fan etc. Remove the label and if there is one, a little rubber bung, you will see the end of the spindle. There should be a small split washer around the spindle, it sits in a little grove on the spindle to hold it in to the fan motor. It can be removed with a small blade screwdriver. Just look for the split and carefully lift one end over the end of the spindle. Keep the washer for later. Then push the spindle out using a something like a cotton bud stem with the cotton cut off the end. It will try to go back in as it has a circular magnet inside the the fan around the outside of the spindle and is attracted to the metal part of the motor with the coils on. Clean the spindle and the hole it fits in then apply a thin grease or something like silicon oil or sewing machine oil. Push the fan spindle back in, put the split washer back and make sure it sits in the groove of the spindle by gently pushing on the end to ensure it does not slide out again. Put the rubber bung back(if there is one), clean any oil / grease from where the label sits and stick the label back on, they don't always stick once they have been removed but it can be replaced with a piece of adhesive tape.

My pc whines when i play a video or game or louder when uploading a video and play games.

A) Processor fan speeds up to cool the Processor.
Gaming, a video, and uploading requires more Processor 'power'.

A Processor has a Thermal Limit. A temperature it can reach, and no more.
Going past this thermal limit would burn the Processor up.
The Processor fan speeds up, to keep the Processor below this thermal limit.

(If the Processor temperature exceeds the thermal limit, the Processor is turned off. BIOS turns it off)

The Processor fan is usually one of two methods used.

1) A fan sitting on top of the Heatsink, which sits on top of the Processor's case,

Typical Heatsink/Fan combo,

2) A computer case fan in the front, that pushes air through a plastic shroud, which envelopes the Heatsink, sitting on top of the Processor.

Perhaps the fan's bearings are going out.

Bad fan bearings will let the fan shaft tilt to one side, and the fan's center hub will scrape on the fan motor.

This can cause a whining sound.
(Goes for examples 1 and 2 above)

Computer unplugged from power, Anti-Static Precautions observed, see if you can gently rock the fan's blades up, and down.
NO perceptible movement should be observed, nor felt.

If so this fan needs to be replaced.

If the inside of the computer is dirty, the added 'Gunk', (Dust, dirt, hair, you name it), will cause the fan blades to be unbalanced.
This will make the fan tilt to one side also.

Computer unplugged from power, Anti-Static Precautions observed, computer case open, use a can of compressed air for computers, and clean the inside of the computer out.

May require two cans.
May also require that you use Q-tips to disturb the outer layer of the 'Gunk', so that the can of air can remove it.

(Would also like to add:

The can of compressed air for computers comes with a plastic 'straw'.
The straw is attached to the nozzle of the can of air, when using it.

A Power Supply should have the inside of it's case cleaned also.
The cooling components for a Power Supply, are it's fan, and internal Heatsink's used inside.

[ Typical construction of a Heatsink is a plate of metal, with tall, thin fins protruding from it.

The plate of metal absorbs heat from whatever object it is placed against, and the tall, thin fins absorb heat from the plate of metal.

The tall, thin fins then radiate the heat away.

If a fan is used in conjunction with a Heatsink, (Such as a Power Supply, or Processor), the air flow from the fan helps to carry heat away from the fins ]

When the fan blades, center hub, and surrounding shroud are coated with Gunk, and the Heatsink's inside a Power Supply, their cooling capacity drops TREMENDOUSLY.

This causes the Power Supply to overheat.
Heat = Wasted Energy.

The Power Supply strains to keep up with the call for power, and eventually cannot.
Components inside the Power Supply fail, and the Power Supply fails.
(As in Kaput)

The Power Supply's case has ventilation holes, on the case side inside the computer.
The plastic straw of the compressed air for computers, is inserted into the top ventilation holes, and air is shot in. (One ventilation hole at a time)

The straw is aimed in a slightly downward fashion.
Then the straw is used in the lower ventilation holes, and then on the bottom ventilation holes.

HOLD onto the plastic straw with one hand, and the compressed air for computers with the other hand.
The straw can shoot off of the can of air's nozzle, and wind up inside the Power Supply's case.

This = NO

No go to the back of the Power Supply, and use Q-tips to get into the crevice where the fan blades meet the center hub.

Also on the edges of the blades, and the surrounding shroud around the blades.

You just need to disturb the outer layer of Gunk, so the air can remove it.
Shoot air past the fan into the Power Supply case also.

You won't get the inside of the Power Supply perfectly clean, but you will extend the life of the Power Supply greatly.

The inside of the computer, and the inside of the Power Supply, should be cleaned on a regular basis as needed.

Different scenarios require more frequent cleaning, or less frequent cleaning.
Only you will know, when you check inside your computer on a regular basis.

You can be the best housekeeper in the world, but even in pristine homes, and businesses, the inside of a computer, (And Power Supply), gets dirty.

(Carpet deodorizer can clog a computer too. It's a fine dust)

If the inside of your computer is kept pristine clean, and you have No fan bearing problems, then your Harddrive is on it's way out.

This explains the workings inside a Harddrive,

(The Spindle motor's bearings are going bad )

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.

FAn problem

I really doubt it. The printers run voltages up to 30 volts, and the rpms could not be enough to cool the CPU, which could overheat and be damaged or get its life shortened. And you would be sealing your printers doom.

as fans with ball bearings in them operate, they gather dust. this dries out the lubricant in the bearings track. normally cleaning the fan would suffice to restore effectiveness just run a vacuum over the fan on a regular basis to stop the dust building up.

if you have added lubricant to the bearings you may find that more dust is now sticking to the dust that was already there reducing the fans effectiveness even more and causing more noise.

another possible reason for the increased noise is that when lubricating the fan, depending on how you did it, you may possibly have bent the fan's axle slightly again increasing vibration and noise.

personally I think it unwise to add lubricant to a ball bearing track such as that on a cpu fan as lubricants vary in viscosity and suitability for use and I wouldn't know which one to buy. If the axle has become bent, I believe it is possible to have it straightened but with the price of fans being so low I feel your best course of action would be to replace the fan and then make sure that your new fan doesn't get clogged.

Fan Noise

The best solution is that you have to buy another new Fan for your pc before it move out of hand.
The fan is faulty and the little checking you have done is some how recommended for the fan to have work better but since then you have to change it for a better one before it have anything to do with your processor Malfunction.

rate this solution .

Loud noises coming from power supply fan?

it might be the fan of your cpu has dust.and making it the fan hard to spindle.if you can dismantle your cpu fan or the fan in your power supply.just clean it with the paint brush.or do it with vaccum cleaner.if you have air compressor the would be better.just blow out the dust.then if you can do it also just putting oil or grease inside the fan at the core.the one that has will smoothen the spindling.ok good luck
