INSPIRON 3521 - FAN CONTROL PROBLEMS

Thanks for the answer.

I used it about 2 days. You're right, the laptop is good but the fan noise is unpleasant.

Yesterday the call center told me that will be an update of the BIOS after 2 weeks.

I hope in a quickly solution from DELL.

Keep in touch.

Hello

I have the same problem with mine.

I've only had it about a week and have hardly used it.

The fan is on full and I can't concentrate on what I'm doing. It's a Substitute character removed as per TOU>

You're welcome.

I know it wasn't really an answer, just a comment.

They are a good company.

I hope so too.

Hello!

I'm from Hungary and I have bought a Dell NB Inspiron 15 (3521) at 2012.12.15. It's service code is . It has come with a pre-installed Ubuntu 12.04 LTS operating system. On the laptop there is an Ubuntu sticker, and the Ubuntu.com website says too, that this laptop is an Ubuntu Certified device. However, I've got a problem with my fan. (I think it's the fan of the AMD Radeon HD 7670M.) When I try to use Ubuntu, the fan is always running on full speed, and it never stops. With Windows there is no such problem. I've bought this device, because it's an Ubuntu Certified laptop, and I want to use Linux. Yesterday I've found this forum, this thread, and I've tried the BIOS A06 that you linked, but it doesn't help.

I hope you can help me.

Thanks and Regards,

Hi all,

we update the bios with the new version A06 and use Speedfann 4.47 to control the temperature of CPU.

We found that:

- in standard conditions (just windows explorer opened) the fan is turn off and the temperature of CPU is between 44°C (min) and 53°C (max) with average 48°C;

- in stress condition (1 video, 3/4 streaming windows opened etc) the fan turn on when the temperature is 55°C and the speed is 2600 RPM (no other speed were found). The temperature decrease to 51-52°C and stay constant.

- the fan turn off when the temperature drops to 46 °C.

The problem about the noise seems to be solved but we think and suggest, for a better protection of the machine, that the speed could be lead to 3500 RPM such to decrease the temperature during the stress condition since the fan isn't loud.

Wait fo answers and suggests.

Hi - I was having the same noise fan problem after purchasing my laptop a few days ago.  I downloaded the new A06. The noise disappeared. Now I hear nothing.  I hope I didn't disengage the fan completely.  Is this normal to be silent now?  Allison

Hi Oroszi,

I do not have much expertise on Ubuntu. If the system works fine in Windows, there might be an issue within Ubuntu operating system. There might be some application running in background in Ubuntu. You may try closing that and see if the issue persists. If you have installed any utility like speedfan, you may uninstall it and see if it works. 

@ Federica: You may uninstall speedfan from computer and then try using it. See if it makes any difference. 

Please share the findings. 

Hi Allison,

If there were any issues with system fan, the system would have shutdown due to overheat and may exhibit other functional issues as well. In case you are experiencing any abnormality, please feel free to get in touch. I'll be glad to assist.

Hello everybody,

I have the same problem. Fan starts work after 10-20 minutes and it never switches off. It makes really boring sound. My laptop is Inspiron 3521 A00. Do you have any update or something to fix this problem?

Best regards,

Nikolay.

Hello everybody,

I read all comments here and updated BIOS (A06 version) but the problem with loud fan still exists. I checked temperature with RealTemp and SpeedFan and it's usually around 50 degrees.

Do you have any suggestion what to do to remove this noise?

Thanks in advance,

Aleksandra Radulovic

Hello Dell,

I have a brand new 3521, I bought it today. Experiencing the same fan problem I promtply installed the A06 BIOS update but the problem still persists, nothing has changed. I would like to know if this is known by Dell and if you are preparing a new BIOS update to eliminate this issue.

Please get back to me for any details that may help you solving this case.

Looking forward to your answer!
