    Hi. I've bought an LG R700 laptop which, unfortunately, is quite too noisy for my taste. The culpritable (and only) fan sits in a corner with two outlets and is connected to the chipset, cpu and gpu with pipes.

    I know for certain that much more silent fans exist, but I don't know where to buy one - or if it is even possible replacing the original. Does anyone have good experience with these two issues??

    Thanks.

    Instead of taking the fan and replacing it,you can try undervolting or even get a cooler.

    I have thought about getting a cooler, but that won't help me if I'm not at my desk. Also, the problem is not, that the fan spins up too often from heat - I find it very loud even at the lowest speed.

    The bottom of my laptop is relatively cool after long use, so I might have some luck with downvolting. How is this achieved? Could I damage some components by trying this, or would the machine turn off if the temperature got too high?

    Thanks again.

    Yes, you cant always just pop the fan out and then back in. As eleron911 said. I do second downclocking though before attempting to replace the fan.

    I have now grasped the concept of undervolting and/or downclocking (and tried both), but these things won't help me, the fan being quite noisy even at the lowest possible level. (How incredibly annoying that LG didn't think to spend an extra 10 dollars on a low-noise fan... :s)

    The only other option I see is replacing it, but it does seem quite hard to remove - I think some of the parts may be welded or glued together. You think the fan itself might be accessed from "above", that is, the top side or with some other technique? Anyone have any kind of expertise in this area?

    Edit: And would I be able to buy a silent fan with a fitting size someplace online?

    Well, you can ask LG about it, maybe it's a defect and they can replace it for you.

    Most likely you will not be able to change the fan, since it will have non-standard dimensions, and different vent/discharge opening, and power requirements than most fans you will be able to purchase.
    Its possible to change the fan, but whether or not it will be quieter is the question. Also you will have to do some serious research to get a matching fan.

    If you really want a new fan, call ebm papst, in germany, and they can custom manufacture fans for you. However, they will ask you to send your fan to them, which means that you cannot use your laptop. This service is quite expensive, so if you want to dish out $300+ for a new fan, that is up to you.

    Ouch, 300$ ? That is WAAAAY too much. And I was really thinking of changing both my fans for quieter ones...

    Well, you can get cheap ones, but the ones I am talking about are high quality german manufactured fans. They are only super expensive, cause they have to make a cad file of the fan, before it is sent to manufacture. Plus only one fan would be made, so its a custom deal.
    I am sure if you look hard enough, you could find similar fans by different manufacturers which will fit.

    You wouldn't know any place online that sells reasonably silent standard-size fans for laptops, would you?
