Hi, the fan of my laptop is very noisy..its very irritating. How can I solve this problem? Is there some remedy for this? Thanks...

CPU Cooling Fan, LAPTOP Fan is broken, I suggest you buy one at: 2egoo.com -professional notebook accessories

Basic construction of a laptop cooling fan assembly:

The plastic fan is mounted in the middle to a Spindle. (Think small metal pole)
There is a small electric motor that spins the fan.

The spindle spins in bearings, or bushings.
Cheaper models use Bushings, better models use Bearings.

[ Bushing: A solid round chunk of bronze (Usually) with a hole in the middle. The spindle spins inside the hole. Also known as a Sleeve Bearing.
Bearings: Usually needle bearings in a cage. Less friction, longer life.

There is usually a bushing on the top of the spindle, and bottom of the spindle.
Or a bearing at the top, and bottom.

The bushings, or bearings can wear out over time.
This allows the small electric motor's armature to rub against the field windings, or the fan's blades to tip to one side, and rub against the surrounding cage. (Shroud)

How to know?
The laptop has to be opened up, and the fan physically checked out. There can be NO perceptible play from side to side. There is however a SMALL tolerance for up, and down.

It may be also that 'Gunk' has developed inside the cooling fan assembly.
['Gunk' = Dirt, dust, hair, food crumbs, etc ]

If too much Gunk has formed on one or two fan blades, the fan is tipped down to one side a little.
The result is the fan's blades hit the surrounding cage. (Shroud)

Solution is to try to clean the air intake duct, and the fan, with a can of compressed air.
Laptop off, ALL power removed. [ AC adapter (Charger) and Battery]

Laptop is held up on one side, (Fan grille opening down towards the table), on a table with one hand. (Towel on table to keep from scratching laptop, or table)

Break the lock tab off of the can of compressed air for computers.
Insert the plastic straw provided into the can of air's nozzle.

Bring the plastic straw close to the grille opening at the top, on one side.
Spray air across the grille at the top.

{Spray air as a professional paint sprayer would spray paint.
Squeeze the trigger in all the way when you start, let go of the trigger as you reach the other side. Refrain from tilting the can. Do not swing the can in an arc when using it.
Keep the can level, and parallel to the grille opening when spraying air}

Now drop down a space, and spray air again. Keep dropping down in rows, and spraying across until you have reached the bottom of the air intake's grille opening.

[When using the can of compressed air it will eventually slow down in pressure.
This is because the air is coming out so fast, that the moisture in the surrounding air freezes.
This can be noted by the can is cold, and may have frost on it.

Let the can sit, and warm up for a while. Then it can be used again ]

Refrain from spinning the fan too fast. The fan's bearings, (Or bushings), are only designed to spin so fast.
Spinning the fan faster than it was designed for can lead to premature failure of the fan's bearings.

{The cooling fan is a mechanical part. Eventually the bearings wear out. Spin the fan too fast, and you will speed this process up. Instead of lasting for years, the bearings may go out instantly, or within, weeks, or months. Premature failure }

Use Short Bursts of air at the fan. Squeeze the trigger in all the way, then let go quickly.


You may have damaged fan bearings already. This would require replacing the cooling fan assembly.
What is the model number of the Asus laptop?
