    i have been searching for the past 2 days for a solution for my situation but with no luck. the situation is as follows:-
    since i always been using hwinfo for all my M18X r1 in the past , the software with EC support disabled allow me to spin my all fans ( CPU, GPU1 and GPU2) at 0RPM, 2000RPM and 3800RPM
    but with Alienware 18 its NOT the case since with EC support enabled i can spin the fan faster but it can ONLY control CPU fan and disable the other two fans for the GPUs BUT disabling EC support allows me to control all 3 fans individually ( which is great except for one huge issue, which is the fan speed limitation which is ridiculous :-
    - CPU fan run at MAX 3700RPM
    - GPU1 fan run at MAX 3500RPM !!!
    - GPU2 fan runs at MAX 330RPM ( for no understandable reason since both GPUs uses the same fan!!)!!!!!!!!
    NOW i have A12 UNLOCKED bios but as i have the 4910QM chip i cant configure the thermal configurations on my unlocked bios since it can only work with MX processors as i got from reading the whole thread of the unlocked A12 . and i know that the fan tables from dell is a joke!!
    i'm doing a lot of overclocking to the CPU ( which this fan setting can handle it pretty well) but GPU overclocking too for my 880M SLI but with this fan setting the temperature is hitting 95C
    i have read EVERY singe thread that has been posted on that matter here on this forum, on hwinfo forums and on two other forums that i cant mention her which took me 2 days to do so, but still i cant find a way to increase the fans RPM for the GPUs . i tried to enable and disable the following
    - TPM check
    - disable Drive scan
    - SMBus suppot
    -install driver in driver manager (hwinfo)
    put no luck
    i don't know if i'm missing something her. please if anyone has any idea how to solve this RPM limitation issue please let me know
    i don't mind control all the fans at once as long as i can jump to higher RPM or at least all of them at 3700RPM
    thanks in advance

    Did you try running the 2 instances (32 and 64 bit) of HWinfo, 1 for each, CPU and GPUs? There was a thread about this sm. time ago.


    Side note: OCing 880ms is least recommend as they already are heavily OCed 780ms, assume you know that.

    thanks for the reply . i actually saw that thread u r talking about but i couldn't get it to run on windows 10 64bit. if u did already this let me know if i'm missing something.
    as for the OCing the 880m i'm actually uing the unlocked bios from svl7 which is great since it only use 1V but allow 144W on the gpu which solved the PWR throttling issue.

    Ok fine, just wanted you to not burn your cards.

    As for HWinfo, I didn't test that cause I didn't need it, my fans spin all same up and down to max, but it's no aw18 either, m17x r4 and m18x r1.

    i checked this thread again and what he was trying to achieve is to get CPU and GPU fans on a separate controllers which i already have without it .
    i still have my M18X R1 i love this machine and yes i have only one slider to control all the three fans

    Ok, I don't know the AW18 that much, so can't help you with that.


    Yes the m18x r1 is a great machine, but meanwhile limited in GPU upgradeability. Often thought bout making it a r2, but then let it be, got the m17x r4 then and went on with that, it's much easier to disassemble than the fat boy...

    I've been playing around with this program for a little while "Notebook Fancontrol" and it works really well, it access the EC register allowing you to set fan values and control the fans really well, it is NOT user friendly as you have to create your own config for your model by finding your models register values for the CPU, GPU1 and GPU2 fan controls. I use it on my M18x R2 for manual GPU1 control (I use 1x GPU). Read the instructions carefully!!

    Here is my config for the M18x R2 but it is unlikely to work for the AW18 as it'll have a different EC. DISCLAMER!! I am not responsible if my config messes up your EC register!! Read the instructions on the github page and understand what you are doing first!!

    Edit* Any mistakes on the EC register can be reset with a CMOS reset... but maybe not all, mine stopped charging from a mistake and a CMOS reset worked for me.:D
