    A few days ago, something happened to my laptop fan in the GPU. In SpeedFan I could see my GPU was running at 0 RPM, I assume its broken. I've noticed lag when I play my games and today I received a message when I was starting my computer up that my fan had broken and needed repairs. I can no longer hear my fan run as it used to. I am out of warranty both with HP and the store I bought it from, so how much would it cost to get this repaired somewhere? (I could not do this myself).

    Fans don't get repaired, they get replaced. There's no point in asking a repair shop. They will just replace the broken fan anyway. If you know what you are doing, you can tear it down and replace the fan yourself. The catch is finding and buying one online. You would need to get a hold of the actual GPU fan in your system to see what part number it is and search Google using that.

    Well first off as others mentioned you replace the fan not repair it fans will die and there is no way to fix other then replacement fan. I would say like another here replied you have to take apart your laptop and get to the GPU fan and there should be a sticker with the part number listed on it. Then go to eBay and find that part number for a "New" and buy that and replace it with that one and that should fix the dead GPU fan. But you need to take it apart to be sure it has two fans one for CPU and another for GPU or just a CPU fan.

    I do have a MicroCenter near my home, It's where I got this laptop too. Compared to other places would that be the best deal? I'd imagine something like Best Buy would be double the price or something.

    Thank you - I am PRETTY sure it'smy GPU fan for the 6770m that's not working, not the CPU one. Which one should I buy in this case? in SpeedFan it says the GPU fan is running at 0 RPM.

    in Hp pavilion dv6, there is only one fan for CPU + GPU as both use same heat sink and one fan.
    SpeedFan can't detect hp fan speed, so you shouldn't rely on it.
    use CPUID Hardware Monitor to detect your CPU+GPU+HDD temperature.
    a simple way to find if your fan works or not, is to check for hot air coming from the air vent at laptop left side, and whether it is speed changes (become louder and more air) with load.
    An easy way to reduce hp pavilion temperature:
    1) use compressed air can to remove any dust blocking air vents (few blows at vents will be enough)
    2) use Hp CoolSense (coolest mode)
    3) raise back of laptop.

    I'm pretty sure it's broken, not only by that but by the fact none of my games run as smoothly as they did before.

    Can someone link me or tell me how to find out what exact product I need to get, and how fast it would be to install it & what kind of technical skills I need?

    this may be helpful, keep in mind that there are minor difference between your model and the one used in the video:

    HP Pavillion dv6 Complete Disassembly and Reassembly 2011 L - YouTube

    you need:
    1) fan (New HP Pavilion dv6 6000 dv6 6050 dv6 6090 dv6 6100 Series CPU Cooling Fan 4 Pin | eBay)
    2) thermal paste (if you do repasting, I didn't as the fan can be replaced without detaching heat sink from motherboard)
    3) screw drivers

    regards,

    Thank you for the answer. So the thermal paste is NOT completely required or do I really need it?

    Thermal paste sits between the die and the heatsink, It allows for better thermal conductivity between the bare die and the copper (or the chip package and copper, whatever you have). So if you remove JUST the fan, your heatsink shouldn't come off (check this) and you wouldn't need the paste. If you do remove the heatsink, even lift it a little bit, you should probably repaste because once air gets through the paste, it isn't nearly half as good.
