    First and foremost thanks to Destiny for reminding me about this.

    To help stop the fan from constantly running at med settings or higher and lower the temperatures, you should open up your laptop and clean out the dust. This will be a guide on how to do so. The process itself is very easy and straight forward. You'll need a can of air. Pictures courtesy of Destiny. I just put in the thumbnails, but if you check out Destiny's post, you can get larger pictures.

    1. Discount your laptop's power and remove an external devices, such as, your mouse.
    2. Remove the battery.
    3. Discharge your laptop by pressing down and holding the power button for 30 seconds.
    4. Discharge yourself by touching something metal. This is to prevent any static electricity from damaging your laptop.
    5. Flip your laptop over and find the screws for the keyboard. These can be found by looking for the little picture of a keyboard next to the right screws.
    6. Loosen the screws until they won't come out anymore. Note that you cannot remove the screws.
    [​IMG]
    7. Time to remove the keyboard. Up near the top of the keyboard you should see these little nobs. For example, there's one between the ESC and F1 buttons. Pull all of the nobs toward you.
    [​IMG]
    8. Gently lift up the keyboard from the top edge (the edge with the nobs). Pull out the keyboard slightly once you lift it up. There's little tabs on the lower edge of the keyboard tucked under the palm rests.
    9. Flip the keyboard over to expose the system internals.
    [​IMG]
    [​IMG]
    Although the picture has the keyboard cord removed, you do NOT have to unplug either your keyboard or mouse.
    10. On the bottom of the keyboard you'll probably find some dust where the vent on the keyboard is, clean that off. Might want to shake the keyboard a little to remove any junk underneath the keyboard.
    11. Now it's the fan's turn. Loosen the screws to the fan. There's two of them. Again you can only loosen them and NOT remove them.
    [​IMG]
    12. Gently lift up the fan and remove it from the internal connection. Pull up on the wires until you can carefully remove the cord from the little plastic connector holder. No I can't think of a better name. Do NOT just pull on the plastic holder because you should NOT remove the plastic holder that's connected to the motherboard.
    [​IMG]
    13. Admire the amount of dust. Especially the likely big piece of dust to the left of the fan (the area on the side of the laptop that spews out air).
    [​IMG]
    14. I removed the film of dust with my fingers. It was a couple millimeters thick so it was easy to remove. You could also use cue tips to remove the excess left over if the film doesn't come off in one go.
    15. Use can of air on the fan itself to clean it out.
    16. Use can of air and blow some out of the bottom of the laptop.

    Before you close up there's something else you can do to lower temps.
    If you feel up to it, you can also apply Arctic Silver 5 to further decrease your laptop's temperature. Here is a guide Destiny made to aid you in the process. There are also plenty of pictures.

    17. Put everything back together.

    Cleaning everything out provided a DRAMATIC change for me. The dust on the side of the fan was literally about 2.5 millimeters thick with one of the sides blackened. Before the fix my fans were always on at least med speed. Now, they're on the lowest setting so they're barely audible or not on at all.

    For a temp comparison, using HWMonitor (I'm just going to list them in order from top to bottom, I don't feel like writing out the names at the moment):

    Before: 53 - 58 - 58 - 49 - 28 - 60 -65 - 62 - 59 - 59 - 41 - 34
    After: 44 - 46 - 46 - 36 - 25 - 47 - 50 - 49 - 47 - 47 - 30 - 34

    Temperatures I'm most concerned about:

    CPU Core 1 and 2 went from 59 to 47, roughly 20% drop
    GPU Core went from 41 to 30, roughly 27% drop

    Thanks for your tip jin.
    there were some strange temperature differences reported here, concerning the Temps of the HD 2600. See the Thread about the HP 8510p new bios, where i posted temps of my CPU / GPU.

    For the GPU temps some remarkable differences have shown up, and i thought i can´t believe the temp readings of everest, speedfan, hw monitor.

    My temps for the hd 2600 were 23°C at idle and the temps never went above 37°C during load. Some users reported the same temps, and others reported nearly twice the temps that i measured on my 8510p.

    Maybe it´s after all a matter of cleaning, and maybe it might be a difference in the thermal compound used. ( or maybe it´s just badly applicated in some cases)

    Thanks a lot for sharing your insights in this matter. I think now my temp readings are correct, and don´t have to worry about wrong temperatures anymore - it really gave me the creeps.

    btw, noise was never a problem for me. My 8510P is very silent since i flashed the bios, that was released in december.

    Right!
    I had some spare time today so I thought I will clean my out :)

    Im posting some pics adding to the description from jin07 :)
    Please follow Jin07's steps and use this post as a more 'visual' ;) guide :)

    [Jin07's STEP 6]
    Start with undoing 2 screwes on the bottom of the laptop - ones next to a little keyboard icons. They dont come out! When You hear a click, that is the furthest way they go.

    [​IMG]


    [Jin07's STEP 7]
    Turn the laptop over, open the lid.
    On top of the keyboard there are 4 slide locking tabs.
    Locked :)

    [​IMG]


    UNLOCKED - just use a small flat screwdriver to push them towards yourself.

    [​IMG]

    [Jin07's STEP 8]
    Lift the keyboard up from its top side, and push it away so you can see cables from the touchpad and keyboard attached to the motherboard.

    [​IMG]


    They both have a smal locking device that you need to pull up and you should be able to take them out.

    [​IMG]

    [Jin07's STEP 11 & 12]
    Now you can take and put the keyboard on the side. Lets have a look on the fan. There are two screws holding it with the motherboard, and a power supply for it. Undo the screws, gently pull the power supply connector up.

    [​IMG]


    That is it :)
    [​IMG]

    Look on the amount of dust I had :) That was last cleaned out aroud 2-3 months ago.
    Clean this out and you can assemble the notebook together following all steps but in the reverse order :)

    [​IMG]

    Have fun and from now on your temps should be around 5-6C lower :)

    Not really. Heat and noise is the price for buying a top of the line powerful laptop. That is why Apple took the clever route of dressing the powerbook in aluminum to better dispatch heat.

    Except that if it's on your lap, that heat goes strait to your body. Not fun.

    Either way, I remember the previous nc8430/nw8440 having similar fan issues, and one way to address them was to use NHC (Notebook hardware Control). I'm not sure if it'll work on the 8510 series, though.

    I dont complain on heat really. The only thing I find annoying is that the fan works on CPU usage instead on temp. But cleaning out the dust really help in lowering temps and noise. My laptop is much much quieter now. I would say silent compared to previously being able to hear it during the night while downloading things.

    hmm, well.... i never experienced that my laptop was too loud. what i was talking of was that after latest bios update the fan got less noisy. don´t get that wrong. at least my 8510p is not loud at all.

    and heat was never a problem for me. even after hours of rendering or gaming the laptop was not hot. it blew warm air though it´s vents to the outside. and like 10 secs after i finished a rendering that was running for hours the fan got silent.

    even if this is a top of the line laptop, it´s not having problems with heat, not at all.

    and btw. the early macbooks were really hot, and at least from my point of view the thickness of the macbook was probably the reason they did not have a good venting.
    and hmm, aluminium was most likely the choice of weight.

    Schoko, how would you describe silent? Maybe we should compare noise with some recordings?? What do you think??

    hmm, how about the sound when the laptop starts up.

    it is designed to run the fan at full speed, cause after a system crash the cpu nad gpu could be very hot, and by this feature HP can prevent some damage.

    that sound is what i would call loud. and thats what i am experiencing when i am rendering. but when i´m working with photoshop, illustrator, maya , rhino..... the laptop is actually very silent. sometimes the fan goes up to the medium fanspeed, when i´m having huge 3d models displayed in shaded mode, with hardware mapping.
    but even that is not noticable when you move more than 1 meter away from the laptop.

    Thanks for putting up the pics Destiny. I was kind of lazy since it didn't look like people needed the thread. Also, you don't have to remove the keyboard and trackpad connection. I folded it over onto the palm rests.

    Thanks for putting up the pictures.

    I'll try this sometime this week since I'll have a lot more free time (almost done exams!). My computer sounds like a vacuum cleaner. Hopefully this helps eliminate (or slightly alleviate) the problem.

    It would be nice to see how much dust did you collect on your vacuum cleaner ;)

    Didn't even need a vacuum myself. The dust clumped up and got burned on one end so it stayed together. If you need any help, feel free. Hopefully this guide helps you.

    i suggest that after cleaning your fan put an air filter at the air intake of your notebook to keep your fan and cooling fins clean. I'm using the air filter on my new 8510p notebook and works pretty well in keeping my notebook innards clean.

    Doesn't an air filter keep your innards clean, at the cost of a slightly less effective heat dissipation through a decline in efficient airflow?
    Still, replacing a filter takes a whole less of effort than opening up and cleaning the bowels of your machine.

    I'm also having examns coming up, but i will definitely perform this and the thermal paste tweak to silence my notebook.

    A little anecdote:

    The noise and heat generated differs strongly on 8510p models.
    My brother has a 8510p with an identical (bios, drivers, most applications) software and hardware configuration as mine, but not from the same manufacturing batch (his is a few months younger).
    Mine has always been close to a vacuum cleaner, while his remains nearly inaudible under the same conditions (e.g. Viewing/Rendering same scene, Gaming same game, encoding video material)

    It seems a probable explanation, like with all hardware, that some versions have better installed cooling elements/paste. Or just a better baked CPU die.
    So i assume that when your 8510p is loud like hell, the margin for improvement isn't that big.

    Still, hoping those tweaks will prove me wrong.

    Maybe he was using his in a less dusted enviroment? Not using it in bed etc. You would be suprised how much dust those little fans can suck out of the air...

    Unjustified: I'm guessing your laptop has more dust in it like Destiny alluded to. I have an 8510p from the very first batch (ordered it right when they started offering them) and it is not loud at all. However, it was loud before I cleaned out the fan and vents.


    I'm not a huge fan of putting in an air filter. For one, you'd probably have to replace it more often than you would clean out your laptop. Cleaning out the fan takes about 4 mins, if that. Plus, by the time you get to the filter, you'd be in a prime position to grab the dust off the side vent. In my experience, it's the side vent that really gets caked with dust. The fan module itself didn't pick up much.
