Maybe we could post another idea on IdeaStorm? There are quite a few issues with Vostro 3450 that need to be resolved, and perhaps a petition to Dell with all those issues described together would make them finally do something.

If you can't return your laptop or exchange it for something else, you'll probably have to live with it. We've been fighting for about 2 years with no result whatsoever, and I don't think things will change anytime soon.

Hey Dolnor,

Do you think it's possible to adapt some of the already existing fan control tools for our laptop? Like i8kfanGUI which supports many other Dell laptops... I'm not very familiar with it, but from what I heard, it's only a matter of changing several variables in the source code. And I also read your posts on HWINFO forum, and it indeed works with Vostro 3450...

Have you heard of the application called Notebook Fan Control? It seems capable of doing what we want, we just need to create a profile for it...

I found it here: forum.notebookreview.com/.../726361-vaio-pro-13-quest-silence-thread.html

Hi,

Common causes for fan running constantly can be due to: An out of date BIOS, obstructions in the fan or vent area, physical damage, dust accumulation in the fan or vent area, usage while not on a flat surface or proper ventilation clearance, using near a heat source or in a hot environment. Fan speed can increase or decrease due to the temperature of the system. I would recommend you to perform the following steps in order which should fix the issue:

1. Ensure if the BIOS is updated correctly to A11 or not. Boot your system in BIOS and check the version.
2. Change the Power Plan. Try changing it to “Balanced”. Click on Start and look for Control Panel. Once you click on Control Panel,a window would pop up. In this window please look for power option. Please click on Power option and change the battery setting to “Minimum”.
3. Check the air cooling vents and make sure that the passages are not clogged with lint and other stuff. Simply raising your laptop off any flat surface will allow fresh, cool air to come in from the intake on the bottom of the laptop. This solves many of the constant fan running issues you might have.

If the issue still persists, run the Hardware Diagnostics. In order to run Dell Diagnostics from Hard Drive, follow the below mentioned step

• Restart your computer.
• When the DELL™ logo appears, tap immediately.
• When the boot device list appears, highlight Boot to Utility Partition and press .
• When Dell Diagnostics Main Menu appears (see Dell Diagnostics Main Menu), select the extended test. If you get any error code, reply with the error code.

You can even refer to the Article ID: 428053 on http://support.dell.com/

My laptop is only 2 months old, so i don't thing anything is clogged yet. And when I wrote about the issue, I was using laptop on the table. I also ran Diagnostics utility fan test, they performed fine.

Hi,

I am going to send you a private message and once you receive it, please provide the Service Tag and contact number, so that I may access to your system records. Please do not share your Service Tag in the open forum.

My protsessor also idles around 55C and fan kicks in after few degrees up.

Hi  DELL-Deb B,

I have the same issue with laptop fan but for vostro 3560 dell even sent me replacement heat sink that did not help at all using bios A11,air condition room temp at 24 degrs,laptop placed on table,this issue does happen at odd timing. right from day one of use.Diagnostic test shows everything fine.some times 47-50 degrs  fan is within the rotating speed & some time even at 47-50 degrs with cpu utilization of 2% the fan is at max speed which causes lot of noise.

Dell says its not known issue when so many customer already facing the issue,no fix yet from dell

My 3450 does the same. Computer sits idle and is placed on the table. Fan randomly turns on at full speed, even though computer is not used.
