    As a computer technician, I come across of alot of overheating GPU's on Intel and AMD desktops.

    An overheating GPU, seems to have a really bad effect on the system's performance, sudden freezes which can only be escaped by a hard re-boot AND of course BSOD's.

    In about 3 out 10 cases a new graphics card solves the problem.

    I have tried those mini-fans specifically built for GPU's but they are a bit gimicky.

    I have just come across GPU Tool and this forum.

    So, is the GPU tool the answer to my prayers?

    I don't think the GPU Tool is the answer for an over heating GPU

    New Heat Sink & Fan, better ventilation, better case fans, and wire management are the answer.

    Welcome to TPU and enjoy your stay! :toast:

    I would say 10/10 a new graphics card solves the problem :D

    Which mini-fans have you tried? At TPU, there is no such things as gimmicky wares, either they do their job or they are not here. (UK2Online may be an exception)

    What prayers do you want answered?

    A definite solution that works everytime!

    You think a new graphics card should do the
    trick everytime?

    This is the best answer. I would add replacing the thermal paste. Keep dust out of the system.


    No offense, but this is awful advice.

    I think the case is the biggest factor for temperature dissapation assuming that the heatink is adequate. Best permanent solution is to increase the intake of cold air and exhaust of cold air. If done correctly the gpu won't need a fan on it just the heatsink. Although I'd still put a fan on it to be sure.

    Buy better cards. I know the shit little fans that you are talking about. The tye that MSI used on my old motherboards, and failed consistently after a few months causing me alot of problems.


    Buy a better heatsink, use a good case fan and you will have no issue.

    These are the crap they come with.


    Replace them with this.

    Just use thermal adhesive glue and then have a slot fan, or a small an blow across it.

    Thanks for all the advice.

    Stevo, how would that Enzotech attach to the mobo of your average Dell Dimension OR
    HP desktop?

    sorry, but i would have to say case airflow.
    from my old thermal take xaser 3 to my new antec 1200 my gpu idle temps have dropped by 12C+
    and my xaser didnt have those crappy stock 80cfm fans either, it had the monstreously loud 80cfm fans.

    cable management does make a difference, but my management is worse(much worse) in my antec 1200 then my x3.

    also try manually adjusting the fan speed thru the driver software. that makes a big difference. i find that a lot of time on the nvidia cards the default fan speed is just set too low

    Yeah definitely apply better thermal paste on the GPU,also maybe new GPU cooler can help to and of course clean your tower every 1-2months.
    Also if you can mount fans on side panel that will cool down your GPU too.

    I`m taking off regular fans damaged or not removing all but the metal fins of the cooler and putting 1 or 2 80mm fans on top of the fins of course after cleaning the fins and re-applying the thermal paste.

    Nailezs, I've never seen driver software to adjust fans...do you have a link?

    On ATI/AMD cards you can install the latest drivers and then in the advanced view manually set the fan speed like so:

    (In this instance 37% is inaudible but keeps this thing from reaching 85C on idle)

    This isn't part of the driver but an addon that can startup as soon as windows starts up.

    Evga Precision.

    This works with most nvidia GPU's. The ones that it wont work with are the non adjustable Duo orb style heatsink cards.

    But as others have said, improve case airflow, make sure the cards are dust free,cable management, and on the cards that you can do it, crank up the fan speed. 50% for Nvidia's is fine since their fans are pretty quiet, 40% for ATi and that's still somewhat loud. 50% and above is almost annoying.

    Good Luck

    KieX, thanks for that great pic!

    I presume that Nvidia has something similar?

    That could be your quick one-stop answer, but as others have suggested, good airflow is important. If I understood correctly that this would be for customers/clients then certainly take a look at the heatsink of the gfx card and blow out the inevitable thick blanket of dust. A quick (my favorite because it's lazy) way is also to use a can of compressed air and shoot it through the vent ;)

    sorry, nver got me e-mail saying that there had been new posts in this thread lol.

    controlling fanspeed is not an add on, atleast not for nvidia gpus of recent generations. with both my 9800gx2 and my gtx285 i can adjust the fan speed in the nvidia drivers, as well as make profiles for automatic control of fan speed dependant upon certain paramenters. i will try to post a screenshot tonight

    Hm.. take the cooler off and replace the stock gunk with something nice like some MX-2. Blow the dust out every few months. Have proper airflow... you should at least have one fan in and one fan out.

    No one has mentioned water cooling!? the best way to keep a chip cooled IMO.

    he's asking in reference to his customers machines form what i understand. so water cooling isnt really a viable option.

    here's a screen shot of the fan control settings and the ability to overclock in the nvidia drivers. this is with Nvidia System Tools installed, but i dont think you requrie them for the video card in order to use these options

    [​IMG]

    this is my fan speed control profile
    [​IMG]


    using this profile i have never seen my video card get any hotter than 55c with my new case.
