What is this fan cooling?

Hey,

I have a problem with my Dell Inspiron 9300 notebook: For some weeks now, the fan at the top left corner (when notebook is in front of you in normal position) often startens to run very fast (and loud) and if this happens, the cpu usage ist dramatically encreased (permanent 100%). I am rather sure, it is not because of some software reason or virus, but a hardware failure. (I formatted the harddisc and installed windows new allready, but still the same problem..)

To find out, what could be wrong with my notebook, I first need to know what this fan is cooling - maybe there is the problem..

By the way, it is strange, that the notebook doesn't get hot at all - so theres no need to run so fast for the fan.

I have added a pic of the backside of the notebook (don't know where the cpu is located exactly).

Anybody can help me?

Thank you!

Kind regards

    I have attached a pic from your manual. The fan on the right is the graphics card  (being the one you are asking about) and the left is the microprocesser. That is with the notebook in the upright position.  If these pics are not all available in your manual, go to dell support and look at your manual.

    Hope this helps.

    Install this small app', set it up as per the manual and it will tell you what fans you have and what they are doing.

    If you wish you can set up the fans and temperature control to your personal settings.

    Works a treat.

    It could be dirty/dusty, get an air canister and stand back.  Check the bios settings, if your not sure (F2 at start up)  then reset the settings to default.  Could also be processor, if that's the case you should buy a new laptop.  (not hot at all is worrisome)

    Take a look at the authors forum.

    They have done some work on Win7 X64 compatibility but I haven't tested it yet.

    I have ordered a Studio 1558 with Win7 so I am keen to get the fan control app' working on it.

    Thank you very much for the replies! I made everything you said.

    I set the BIOS back to default, but it doesn't change anyting.

    I installed the I8kfanGUI software and the fan now works normally again and also the cpu usage doesn't encrease to 100%. This is great!

    But: The cpu usage is still very high (permanently about 20%, in former times it was about 5 %) and if I start a programm (like word), it needs very long to load (in former times one second). Also I cannot watch videos or play games, which in former times ran without any problems. He is even to weak for playing YouTube Videos smoothly!!

    When I open the taskmanager to see which process needs so much cpu usage, there are no abnormal tasks (only system, svchost 5-10 % each) but when tastkmanager started, the tastmgr.exe itself needs about 20%!!

    It is an Inspiron 9300 with Intel Pentium M 760 (2 GHz) Processcor, 2 GB DDR2-SDRAM and 256 MB NVidia GeForce 6800 Go graphics card. It was bought 2005 and it always did a good job until this problem with the fan and the cpu usage occured.

    I am rather sure, that it is not a software problem, because I allready set up the notebook completely new (formatted and installed windows new), but it is still very weak.

    Any idea, what I can do?

    Or is it normal that notebooks get more slowly and weak by time??

    Thank you very much for your help!

    Kind regards from Austria

    Hi there, I do not know whether anyone notices this problem. I recently bought an Inspiron 1440 laptop. I got it fitted with a graphics card so that I am able to play some games. I noticed that when the display is opened, it is blocking more than half of the air vent. Please note the air vent of this model is located at the rear of the laptop. When the laptop is performing at its peak during game play, the fan would run to cool the internal hardware. The manual stated user must leave at least a 4 inch space at the back of the laptop to prevent overheating. However, when the display is opened, it will block more than half of the air vent and the gap between the display and the air vent is about 1cm. I am really concern the gap is too small and much of the vent is blocked by the display. Will this cause overheating during game play and other activities that need high processing requirements? Why the design and positioning of the air vent and display are like that? Any ideas or thoughts are highly appreciated.
