    Say, a friend of mine suggested cutting the yellow wire (the tachometer?) on my fan to make the fan run at max. I told him my laptop has this "turboboost" button which sets my fan to 100%.

    Will his suggested mode make the fan run at maximum speed beyond turbo boost? Thanks.

    I tried that with my older msi laptop (msi GT627), the result was that the fan would sort of pulse. It would speed up and slow down and speed up and slow down over and over.

    If you want it to stay at it's max speed, just connect the fan to a usb port (5v), or any other place you can take 5v from on the motherboard. Maybe even go 6v or 7v for more speed, but your fan may burn out past 5v.

    indeed, it's 12v. So, Yellow wire or stick to the good ol' turbo boost?

    Wait what? Why would you manually force your fan to 100% all the time forever when you have a button that already does it which you can turn off?

    What Meaker said. This isn't a mod, this is gimping your fan making it work hard all the time and ending its life cycle sooner when you have a button that allows you to manually turn it to max.

    i think the original question was if the fan speed button was actually releasing the fan to maximum potential or if it just setting it to a higher speed below its full potential.

    i did this mod on my g50vt x5 a while ago but it was cutting the blue wire not the yellow one, i forgot the proper name of the mod. I attached a switch to reconnect the blue wire so that i can manually control when it runs at 100%

    When the cooler boost button is pressed the fan is set to max speed.

    Yea I don't see what this accomplishes besides trying to lower your idles so you can show them off. It'll just wear out your fan faster and make it work hard when it doesnt have to.

    haha well I wouldnt put it that way.. maybe he plans to overclock, a faster fan is always better for cooling more airflow. fan death is way better than cpu or gpu death but its been resolved this mod isnt going to give more rpm on the fan.


    maybe he wants to vacuum his room.....haha.
    ive noticed that my gx660 pulls all the dust in the air towards it during turbo fan mode :p

    Though that may work for many laptops there are inherent faults to placing copper blocks. if it comes loose it can cause a short. or it can block airflow to a point that it retains the heat. either one will cause heartache... just be careful haha

    Yeah use a decent quality thermal tape/thermal epoxy and perform several thermal cycles before moving it.

    @Niff

    LOL, i was actually considering the first one, then I noticed that it only blows air in one direction. (The msi fan blows in two)

    But damn, how would I fit that thing? :D

    Or maybe we can somehow overvolt our fans to spin faster? :eek:

    It's about 4W total for the stock fan IIRC.
