    Cool idea! How did you attach the fan?

    Hi :)

    Heaven Bench 2.0 (2loop) Temperatures GPU-Z 0.4.2:

    I connect the fan with rigid wire and skill :biggun:
    The fan is connected to the motherboard (connector PWM):

    Idle: 1000 RPM
    Full: 1500 RPM

    Darksnake3.

    excellent idea...the best ive seen yet as far as results go.

    Did you by any chance also change the tim* on the gpu??? ive also heard that it is gooped** on, and using AC5 or better, results in lower temps also...

    I´m not a great fan of mods but this one rocks!!! Kudos DARKSNAK3!!!

    By the way, can you show us how much you can overclock the 470 like this please???

    I would keep a close eye on the temps of the other components. As you can see, the heat sink that you've attached the fan to only cools the GPU core.

    [​IMG]

    The original fan and the shroud were designed to cool other vital parts of the GPU as well. The shroud likely channels some airflow thru slots to the ram, vrm's on the PCB under the chasis:

    So I would be careful here, other parts may overheat, esp the vrm's.

    The card dis-assembled to give a better idea:

    nice mod, but also make worthless the stock fan of the card because the plastic assamblay redirect the air blowed from the fan to the heatsink and others components, also important what alanm said about to cool down memorys and surounded area


    ps. btw, if i were you a removed the ugly sticker of the plastic assambly you removed.. lol..

    A bit misleading topic, I was going to call you a troll, because I tought that you were telling that you got core to -20dec Celcius with air cooling :p

    20dec Celcius drop, very good job. I dont think that adding that big fan could increse temps of other parts, even tough it might cause airflow to be a bit different, but original fan is still spinning and cooling other parts of that card. And it's still core which heats up the most. It looks to me that only parts where there are thermal stickers installed which arent cooled by that 120*120mm fan are under that original fan...

    Most efficient would be cutting out the part for the extra fan, so the default fan still sends all of it's airflow towards the back of the case.

    But then again, it would require you to cut up some parts on a shiny new gfx card. Hopefully within a few months, we'll see some nice after market coolers for this card.

    I wouldnt touch the Thermal paste if it works. 1-2c isnt worth it if its risk (which I've heard its pretty risky taking it apart). If someone told me 5c, I'd think about it. That is a great idea for a mod though. I cant believe it wiped 20c off some things. Thats incredible! Its not the prettiest thing, but its probably just as good as some of the aftermarket coolers that we'll see soon. The only problem I'd have with it, is that it dumps all that 'thermi' heat into the case instead of out the back.

    it looks good to you?
    ok then but that dont make it good .... i can understand you not wanting to do a stock cooler mod right, np dont mind me what would i know anyway.
    imho its a waste of time to do a fan mod but not to change tp with something better.
    do it the kiddie way what the hay
    i call bs on the temp savings anyway

    not to take anything away from the mod at all but jeez

    Didnt mean anything against you cowie, I'm just a pussy when it comes to messing around with the small resistors and stuff :D.

    "Not to take anything away from the mod, but I call BS on the fact that it helped"

    Come on. A fan is going to net you far more savings than thermal paste change. And while I would personally redo the paste because I always do, it's not necessary and has never netted me more than a couple degrees, while attaching other fans has saved me 10 before.

    We know the metal parts of these cards can get hot enough to burn. This tells me that the thermal transfer is clearly sufficient to get heat to the cooler, so where's the thermal "bottleneck" so to speak? Clearly its in the fins, in the dissipation capacity. If you increase the airflow/turbulence over metal surface of the cooler then is it not obvious you will reduce temps?

    Your method simply makes the fins very slightly (probably unmeasurably) hotter. Thermal paste change is irrelevant in comparison to strapping a fan to it, don't be so elitist.

    Finally there is someone who understands the concept of heat transfer.:thumbup:

    Hey "DARKSNAK3" great. I did kind of the same thing the other day. Well while useing MSI for fan.. for some reason it got stuck at 40% while playing a game and I never noticed the heat of the card at 109.. or little higher. Shows you the cards are made to run very high. Yet I did NOT like that. So I took 2 ATI CPU fans but on top (like you did) and now idles at 34, and max with overclocked VERY high.. 73c. Yet what I LOVE is you NEVER EVER hear anything.

    ALso I did ..when I got the card clean off the GPU.. man they put a crap load on for like 5 gpus. Way to much. (EVGA)

    I will be doing a fan mod if/when I get a 470 now, just because of this thread.
