    Want 100% fan speed but don't want to overheat your card to get it? Haven't seen many people post about it but there's a really easy way to force the G73 to run 100% fan speed all the time. It's easy to reset too: just shut down your computer and turn it back on.

    Here's a guide (pictures can be added later if necessary/requested):

    1. Download the program called 'RW Everything' from the creator's homepage HERE: RW - Read & Write

    2. Install the program, and open it up. Up near the top, you'll see a row of icons. Click on the one that looks like a laptop and has the letters 'EC' on it (this is the Embedded Controller function)

    3. You'll see rows of numbers in columns on the X axis and Y axis. The bit you need to modify is located at 00x90. So go to the right one (top column will be 00), and then go all the way down to 90 (left column, it's right above A0).

    4. Where these two meet, you'll see '00', right below '02'. Double click on it, and a little box will appear. It'll have small rows of numbers going 7, 6, 5, etc.

    5. At the very bottom, it'll say '00'. Click on this and change it to '01'. Click OK.

    You'll hear your fan go to 100% and stay there. This keeps your laptop running MUCH, much cooler.

    If you want your normal (quiet) fan speeds back, simply hit 'Shut Down' in Windows to power the laptop off fully, and then turn it back on. It'll reset the bit value in the embedded controller to 00, and your normal fan speeds will function as usual.

    Note: While this will keep your laptop running much cooler, it could also potentially wear out the fan much quicker, requiring it to be replaced sooner. Keep this in mind, I really only force the fan to 100% for gaming to make sure it lasts longer.

    Note #2: I've tested this on an Asus G73JH along with a G60JX, and it works on both. This should (in theory) also work on G73SW's, G53's, and G60VX's along with possibly G72's. I make no promises, but you're free to try.

    Enjoy. If this is old news, I apologize in advance.

    Yeah this has been done for the G51 but it's good to know the same works on the G73. If a reboot doesn't reset it pull the battery and AC obviously. :)

    Are your temps that bad that you need the 100% fans constant?

    I've done some deep research with RWE on my Acer. There are some fancontrols for Acer which changes the right EC registers too.

    I see some interesting registers yet.

    03-90 (147) - CPU fan rpm
    05-90 (149) - GPU fan rpm
    07-90 (151) - CPU fan on (01)/ off (00) - can be set
    08-90 (152) - GPU fan on (01)/ off (00) - can be set

    No, but I live in Southern California and I'd rather be safe than sorry with how hot it gets here. I do know that there's quite a few people on the forums that hae overheating/cooling problems and I figured someone would benefit.

    Plus when games are going I can't hear the fan anyways. :eek:

    Still, you should have decent temps no matter where you live with the dual-fan cooling...
