    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.
