[not so serious hint]
You can also solder the fan's cable directly to the PCB of the graphics card. I once did that since the connector broke. But thats a more of a I-don't-care-since-it's-an-old-card-and-my-warrenty-voided-a-year-ago-anyway-and-i-had-to-bake-it-twice sort of thing to do. (got to love the 8800 cards of nVidia)

Will any PWM fans work? I havent soldered before and the card is brand new so no modifying tongue.gif

EDIT: What about a 2pin to 4pin connector?

id go to your mobo fan header of get a fan with a speed control built into the fan. They are cheap enough and work well

I'd prefer to control the fan through EVGA's Precision X rolleyes.gif

then you need to back away and stay with stock cooling or move to real water cooling. you are not seeing this mod for what it is and thats basically a ghetto mod. if you want everything to work correctly and just fit then spend the big bucks and do it right.

Although the fan connectors on the graphics card work the same as on the mobo (although controlled by different software) they are smaller then the ones found on the motherboard. Connecting a case fan to the smaller connector is impossible without getting your hands dirty. Although soldering isn't hard, you do need to invest some money into buying an iron. Maybe you have a friend who happen to have one smile.gif

I understand the desire to control the fan with the gpu turning software. There is no other way of setting the speed of the fan dynamically based on the GPU's temp (as far as I'm aware).

The only thing that comes close is the thermal armor of the ASUS sabertooth. There are multiple measurement points along the mobo and you can set each one of them as a driver for whatever fan connected to the mobo. There are sensors for the separate PCI-E 16x slots. But the temperature of the motherboard will hardly rise when you applied "The MOD" on your card wink.gif

speak of which, you will be modding your card quite a bit by removing the stock cooling anyway wink.gif

[edit] it's not required that the fan is a 4 pins in order to work. But it might if you want to tune it with Precision X. I'm not sure how this works. Maybe someone else can shed some light on this,

ASUS GTX670 DirectCUII TOP wheee.gif

NOOOOOOO DONT DO IT!! The asus direct cu ii gtx 670 top has an amazing cooler already and ull have a hell of a gain getting temps right if you go back to stock. Also did you know the bracket with the 92mm fan from DWOOD is no good for the GTX 670 as the VRM's arnt in the same place as previous cards!

I had to reapply thermal paste 5 times before i saw good temps again on my gtx 580! AIt suprised me how much TIM a GPU needs!! When i took my IHS off for the first time, it was overflowing!!! Asus use loads of the stuff!

You don't think there will be a noticeable gain? The airflow from the 92mm fan should be fine to cool the VRMs right, they dont get -THAT- hot? There was a huge difference with the 480!

as someone with "the mod" in sli in a matx case and as a 670 owner (who tried the mod on it) i think i can at least post a little helpful info. if you want everything perfect then pay for it, the fan needs to be powered from either the motherboard or the 4 pin adapter unless you want to solder and void a warranty. second thing is i tried the 620 on my 670 and saw no improvement in noise, temps or OC headroom. its a quiet card that OCs fine and keeps temp under control. you would be wasting time and money on doing the mod to it but you are welcome to try for yourself and report back your findings.

Well I already have my Antec 620 on my old GTX480, so I was just going to put the 480 back together and sell it to a friend, and move the Antec onto the 670... if its better as is then I'll just let it be thumb.gif

its that good and then some. only reason i didnt keep it was because it couldnt keep up with my 470s in sli but for a single card solution it is amazing. the temps when OCed were around 70C, it was super quiet and used less power.
