Fan sounds like a commercial jet engine

After about 1 or 2 hours of light use (internet, word processing), the fan on my computer becomes as loud as a commercial jet airliner.

I have the program Speed Fan on my computer and the core temperature of the processors does not change.

They remain at 36 and 38 degrees.

Should the fan run faster/louder if there is no change in the temperature of the processors?

The computer is still under warranty. I would rather not send it back for something litte that I could fix myself.

 

Try using HWMonitor and monitor the temperatures, Speed Fan is not very accurate when used with notebooks and can bug out.

 

It changes to maintain that temp. I have many ideas but think others might have better advice.

 

First try cleaning the fans from dust. A vacuum cleaner can do the trick.

After that try the undervolting guide.

 

Good point but why should an owner of a notebook need to resort to undervolting? Do not get me wrong I like to play with that. But that is not normal.

But if you guys do who am I?

 

Did the cleaning. Still loud.


I would rather have another solution.

The computer is still under warranty. I would rather not send it back for something little that I could fix myself.

 

Has it always been this loud, from the first moment you got the laptop?

 

Yes. I didn't think it was in issue initially. I thought some computers were just louder than others. It was only recently that I realized it was an issue.

 

Under volting is your best option. It's totally harmless and doesn't void warranty.

The only other option I can think of is active cooling like notebook cooler or better air conditioning.

 

RMA it? Why does a consumer need to do so much?

 

You might also check and see if their is a bios update and/or video driver update for your laptop. Often cooling/fan options are programmed into those drivers. Some bios also have options for fan speed.

i.e. Windows update offered me an update for my Nvidia display driver and after installing it my fan ran full speed almost all the time. I had to re-install the original driver and hide the windows update driver.

 

NEVER EVER USE A VACUUM you can fry your motherboard among other parts of your notebook due to the static electricity build up.

 

Yup, use a can of compressed air instead.

 

And where does that static come from??

If you claim airflow then canned air would do the same.

A vacuum cleaner is 100% fine, you just should be careful that you don't bang against anything if you need to open the laptop - and if it spins the fan too quickly it could damage the bearing.

On that note - maybe the bearing in the fan is breaking?

 

I noticed that the OP hadn't answered the question about the temperatures and if Speedfan was giving him wrong readings. Are they high when viewed in a different program, like HW monitor?

If the the temperatures are still low, I'd put my money on Detlev's hypothesis that there's something wrong with the fan bearings.

 

Just make sure that you restrain the fan before you let the air jet flow by. I destroyed the bearings on my fan with unrestricted air flow causing the vanes to rotate faster than rated capacity.

 

I never had a problem with using the vacuum cleaner on the fan exhaust area.

Maybe I've been lucky I don't know.

 

I just think its paranoia by other people - there is no reason why static should occur in the first place.

 

A vacuum won't damage it, but it doesn't provide enough suction to get all the dust in my opinion. Try canned air with a straw to get most of the dust out. Too bad opening it to take the fans out would probably void your warranty.
The Bios update might fix it too. Beyond that, you have to send it in. Do it before warranty is up!

 

Depends on the vacuum cleaner
And on the type of dust.

If you have a dust layer in front of the grille inside, then canned air won't do anything and a vacuum cleaner pulls it out.
If its dust on the blades then the canned air is better.

Oh and type of vacuum cleaner, we've got a Dyson

 

What are the fan bearrings and how are hey repaired?

 

They allow the fan to spin smoothly and you cannot repair/replace them. You have to replace the complete fan assembly.

Since the computer is still under warranty, even though you would rather not send it back for repair, and you have tried updating bios, drivers, cleaning external vents, etc. I think it is time for you to use your warranty. If you have the chance to hear a laptop like yours in a store and it sounds significantly quieter, send it in for repair, IMO.

 

This is pretty much the right answer.

Only way to have that repaired is by having a new fan installed.

 

depending on a laptop, you can replace them. I did. I broke the fan a short while after though)))) it wuz an accident)))

 

I commend you on your diligence in locating and installing new bearings. Although not impossible to perform as you indicated depending on the manufacturer I would not recommend that approach for the average individual, just replace the fan assembly.

 

i would use a can of compressed air and then do the undervolting guide and get a notebook cooling pad.

 

I don't know if this can help solve the problem.



When I put the computer into "Sleep" mode and then one second later, come out of it, the fan goes back down to 2,200 RPM from 3,800 before going into sleep mode.



Could this indicate anything?
