    I have a DV7T-1000 hp
    version 6.6.6002 service pack 2 build 6002
    x86-based pc
    bios hp f.12 8/28/2008
    smbios version 2.4

    My fan has recently started running almost constantly and loud. I have gone into msconfig and gotten rid of everything that doesn't need to run. The computer will do this when stationary with fan area hanging off of table exposed. When I sleep it or shut it, the light on the exterior of the computer (that says hp) stays on and the fan runs on high. I don't believe there is dirt in there. Around the same time, I noticed number lock and the keypad on the side stopped working.

    could part of this be that I have never replaced the battery?

    What else could it be?

    I have run every spyware program known to man (malwarebytes, superantispyware, etc)

    Thanks in advance

    Install this software and report back with the displayed temperatures when you have no programs running. CoreTemp

    tj max 85c
    core 0 58c min and max 58c load 0%
    core 1 58c min and max 58c load 0%


    Should I update or change something in BIOS?

    Those temps are quite high for 0% load, they should be about 20C less than they are.

    This a sure sign that the heatsink is in need of cleaning. You may improve the problem by using a can of compressed air to blow through the vents but dismantling the laptop to give it a thorough clean out would be more effective.

    The second readings are below normal. Was the fan still running at full speed and when were those readings taken. To get a true idle temp you need to check it about ten minutes after boot up or after the PC has been idle (no software or browser in use) for ten minutes.

    What temps do you get when you have been gaming or running video.

    Try this software Speed fan. This will also display the fan speed.

    Could it be that the fan has just become noisy and therefore giving the impression it is running faster? Is it much noisier than it used to be when running video or gaming?

    This is where we are after 10 min after startup and pc has been idle.
    Fan is not going at the monent. Nor was it when i posted the last temps.


    I do not game or run much video.


    Could it need a BIOS update or anything else?





    Tj max 85c
    Core o 40c min 22c max 40c the load number keeps changing
    Core 1 40c min 22c max 40c the load number keeps changin

    Those temps are fairly normal.

    You are saying the fan is not running, in your opening post you said it was running flat out all the time, has that situation changed?

    I think you will find the fan is still running it's just going at a slower speed, did you use Speedfan to check the fan speed as I suggested in post 6 ?

    The Bios is not likely to have any influence over the situation.
