    Post the laptop manufacturer name, and model number. Model number is on the Bottom of the laptop. Your laptop is dirty inside, and the fan's bearings may be bad. (Bad fan) Post back in a Comment.

    I'm going to guide you in opening the laptop, cleaning, and diagnosing the Fan, plus replacing if needed. My thoughts are if you wanted generic answers go to yahoo answers.

I agree with joe, clean fan, vents, fins, etc. Avoid using a laptop on a soft surface that restrict air flow. Improve/ increase ventilation and air flow , if necessary use a Laptop Cooler.

WHIRRLING NOISE


take the side of the case off and carefully stick your finger into the center of each fan to slow it down, if the noise stops, it's time to replace that fan, which is easy enough.

My dell inspiron laptop produces howling


I believe the problem may be the cooling fan, of the Fan Assembly.

Dirt, dust, hair, food crumbs, lint, you name it, can be drawn up into the laptop by this fan.
This can cause a strain on the fan's bearings.

It could also be that the fan's bearings have simply failed. They are dry, hence the occasional howling noise.

The method is to open the laptop, and physically check the fan.

Dell Support > Inspiron 5100 Notebook PC > Service Manual,

http://support.dell.com/support/edocs/systems/ins5100/en/sm/index.htm

FIRST thing;
FOLLOW Anti-Static Precautions.

Anti-Static Precautions:
Your body carries Static electricity. Static WILL fry out (Short Circuit), the delicate hardware components inside a computer.

Suggest wear an ESD wrist strap, and connect it's alligator clip to a good ground source. (Electro Static Discharge)

Basic example of an ESD wrist strap,

http://www.radioshack.com/product/index.jsp?productId=2103245

[ I connect to an unpainted surface, of the metal frame of an open, empty desktop computer case. Just one example ]

On the Dell Support > Service Manual page, click on -
Microprocessor Thermal-Cooling Assembly

This shows the Fan Assembly. It is connected to the Microprocessor Thermal-Cooling Assembly.

Another view of the Fan Assembly,

View of the Microprocessor Thermal-Cooling Assembly, with the Fan Assembly,

See the 4 screws sticking up, and the squarish metal plate they go down in?
This plate sits on top of the Processor.

The two curved slightly flattened copper pipes, are Cooling Tubes.
They are sealed on both ends, and are filled with Nitrogen.

They attach to the squarish metal plate, that sits on top of the Processor, and the other end of them goes to a Heatsink.

This cannot be seen in the photo.
The Heatsink is a rectangular finned object.
Has Tall, Thin, fins.

Heat is absorbed from the Processor, by the squarish metal plate sitting on top of it.The Cooling Tubes then absorb the heat from the squarish metal plate.

Heat is then transferred along the Cooling Tubes, to the Heatsink.
The Heatsink absorbs the heat, then radiates it away with it's fins.
Air from the Fan Assembly, helps carry heat away from the Heatsink fins.

The Fan's blades, center hub, and surrounding cage, (Shroud), must be clean. If the fan's blades are dirty, the result could be an unbalanced fan.

Makes the fan tilt to one side, and possibly scrape the blades on the Shroud.
Also over time the dirt, dust, etc, can cause the Fan's bearings to fail.

Gently see if you can move the Fan up, and down. Gently grab a blade of the Fan, and see if you can move the Fan. You will know if the Fan's blades have too much movement up, and down. (Or tilt to the side)

If the Fan is bad, (Bearings), see if you can buy just the Fan, and replace it.
If not you may wish to replace the entire Microprocessor Thermal-Cooling Assembly.

Should this be the case post back in a Comment.
I need to guide you in proper replacement.

[ You need to Thoroughly clean the top of the Processor, and the bottom of the squarish metal plate that sits on it.
Then Thermal Paste needs to be Properly applied, and the 4 screws tightened down in a sequence ]

Microsoft cooling fan not working


Are you sure there is adequate airflow for the notebook? Make sure it's setting on a flat surface, with nothing clogging the vents. Ensure that any vents and fans and heat sinks are free of dust - consider blowing them off with compressed air (power the system down first, of course). Are the any BIOS settings for the temperature settings, set lower than the manufacturer recommendations or defaults (you would need to check your notebook manual for this). Also ensure you're running the latest BIOS version (again, your notebook manual would have the details; the manufacturer's website should also have this information).

I hear noise coming from the back vents and I think it might be the processor fan. Is there a way to fix/clean it so that noise goes away and do I have to open it from the bottom? This is for Qosmio G25.


You probably need to replace the cooling fan, but you can try cleaning it out first. Get a can of compressed air or use an air compressor to spray pressurized air into the vent to spray dust out. If this doesn't work, you probably need to replace the fan. I actually found a guide for opening up the Qosmio G25 and replacing or cleaning the cooling fan. Check it out:

Describe your Lenovo 3000 Y410 Laptop Computer - Intel Core 2 Duo T5450 1.66GHz, 802.11a/b/g Wireless, 2GB DDR2, 1 PC Notebook Problem.Buzzing noise from left bottom corner


Welcome to Fixya.

The system fans are located at the bottom left of this laptop. If there's noise, then it means that the fan is working to cool down the processing. If the fan noise is too loud, then it needs to be replaced as soon as possible.

You can check for replacement/repair options through Lenovo's support site :

My problem with my Sony VGN-SZ330P is the fan, it producing some loud noises, sounds like its grinding something


You can blow compressed air into the cooling vents of the fan. If you notice clouds of dust coming out, then it might be a good idea to disassemble the laptop, clean the fan & air ways, & reassemble it back. If the fan has failed & is no longer running, it might need to be replaced.

Seems to be a noisy fan on mb4210 combo


Could very well be the fan. The motors can cause interference. There may be a solution to get rid of the noise. Some copper shielding tape may help. You could rule out it being a microphonic preamp tube by turning the amp on as normal and tapping the tubes with something non-conductive. If you hear the tapping noise coming thru the speakers while doing this to a particular tube, replace it. With power tubes, the tops of them turn white on the top when they become microphonic, along with plenty background noise.
