    Hello Guys

    Just wondering, has anyone seen this by CEG (Clevo):

    https://drive.google.com/file/d/0B-HucYh908-yVnBJOFY4T2tVYkU/view?pli=1

    I do not take credit for this, just wondering if anyone has tried it.

    I have my 2 980m's sitting in my kitchen drawer waiting to be installed in my Alienware 18, was considering putting them on ebay untill i read this?

    Will this work??

    Looks as if it will... I am hoping this is good news!!

    According to that its simply a PWM issue with the fan not working correctly on the 18..?

    Same issue I run into with pwm corsair fans. The pwm signal is not standard in the fans and require an amplifier of some kind especially when you try to control more than 4-5 fans on one header or a fan controller that corrects the signal such as the aquaero 6xt.
    the link provided I think would probably work, it's simply putting both signal wires on gpu fan header one. It's a simple and fast thing to try.

    Yup,

    I've had a AW18 from a client that had this mod, worked flawlessly.

    So you unplug Pin 3 from the 2nd GPU Fan and connect Pin 3 from the 1st GPU Fan? Or do you leave Pin 3 on GPU 2 plugged in and add Pin 3 from GPU 1's fan?

    I am still debating if I should upgrade to SLI GTX 980M or stick with my SLI GTX 880M... Wish Dell would have told me that they were going to discontinue support on my $4000 laptop before I purchased it last September.

    I love the Laptop but the main reason I decided to let go of $4000 was the fact that I was told it would last me 3 plus years. I am very disappointed with Dell and I knew they were going to screw over the Alienware brand... Just thought it was going to happen years ago...

    What can I expect if I do upgrade to SLI GTX 980M? stock speeds with no throttling, but no over clocking? Or are there issues with stock speeds throttling?

    What you can expect is

    +Short burst of happiness
    +Kinda good performance

    -Frustration
    -Low bank balance
    -Non-existent support
    -Weird problems
    -Did I mention frustration?
    -Cards randomly dying

    + Increased post count from creating help topics because your cards/laptop died (again)

    Take it from me, don't go there.

    Pardon me, I may understand this a bit wrong, but wouldn`t this present a risk?
    If you hook one GPU fan (GPU #1) to the connector to the other GPU fan (GPU #2), isnt there a chance that the temperature of GPU #1 exceeds a certain limit because the fan always kick in because the temps of GPU #2 control both?

    Got to make sure you make the GPU that run the coolest of both, make that the slave. Not the other way around. Because usually one of them run 3-7C higher than the other.

    That's the problem. Only one fan is kicking in so it will have to be connected to the fan the MB is telling to fire up.
