What I am about to show you is something that is not for the faint of heart and I will not be liable with what you do to you card. The process at first for me was a bit daunting considering what would happen IF.... After doing some practice, I realized how easy it is and I proceeded with the installation. As I am writing this, my mind is blown away by the amount of money I have just saved going this route because I could not afford to spend another $500 using a watercooling setup for my $500.00 gaming card. Attaching a cpu cooler is quite possible with the bracket which was provided by Dwood over at overclock.net. To think that a $9 bracket would hold a Kuhler 620 to a gpu die did not cross my mind but hey, it happened.
 
Here is a 2 pictures of the bracket with my Noctua 92mm fan attached.



Installation is pretty straight forward and the pictures can speak for themselves.
Here is my baby But%^naked.

 
Removing the shroud and the heatsink and fan is super easy. Removing the shroud from the 400 Series was a pain in the butt and was quite easy to break the pins.
 
Here are pictures of the bracket holding the PCB and Kuhler in place along with my system once installed the case.




 

There were to things that I had with me to ensure that everything was operating at normal temperatures. Pictures below.
 


 
Here is the fun part and where my hard work became evident an hope you enjoy. Here is a picture of my idle temps after 30 hour on desktop.


And here is a picture of Heaven after 30 hour under 99% load in continuous looping.

 
My system during these runs was dead silent and running quite cool. The purpose for the Temp gun was to extract readings on the back of the PCB board and the heatsinks. Under load, the highest I saw was 140f on the back of the PCB where vrm sits was 135-140f. In the front I had to squeeze the lazer between the fan and the heatsink where the sinks cover the VRM was reading 120f because of the 92mm fan. The left side of the PCB where the left vram chips sit were 120f and behind it were 125f. Finally, the back of the PCB where the GPu die sits was only 7 or 8 celsius than the gpu under load.
 
Room temp 23
Idle 25
Load 49-50
Dba could not hear.
One added plus was that during the looping my GTX 680 did not downclock. Hopefully this card will live much longer because of the cooling.
 
I am not much into overclocking, but I overclocked the card to 1259 and temps rose only 2c during the heaven loop with no crashing.
 
What do you guys think? I tested other games Skyrim 37c to 42 under load. Battlefield 3 46c load, Mass Effect 3 37c load.
 
ps. the bracket is compatible with h50, h70, kuhler 620, kuhler 920. He also make brackets that will fit other corsairs; just pm him with what you would like.

+1 no pics here either

Sorry, My internet was clunky for a moment.

tempting ....ive got a FTW4G on the way .Thanks for detailed pics!

Hell ya! Ghetto riggin ftw! =)

Looks neat; thanks for sharing what you learned.

               
     Thanks EVGA for listening to your customers: Re Join the petition for a 670 FTW backplate.

What about cooling the VRAM?

Check on the bottom of my post, I have all my temps there.

Ahhh I see, thats what that fan is for.  Not bad, not bad at all.

I find the fan more effective than stock because it has a bigger fan and it is blowing directly over the vrms. I put my hand in that area and I can feel alot of air moving.

Very nice man, love the simplicity of this!

 
 Very nice! Good job!     

Truly thanks for the ribbon moderators. Been at the forums since 2007 and hoped that on this one, I could contribute to the community.

wow that's cool dude!
edit: that's kuhl dude!!
 

Awesome mod!

Awesome work on a very functional mod to keep you graphics cool. Great to see the design and implementation. 

Very simple and very effective, by the looks of it. Nice solution. Should be viable for those having heat issues.
Now if EVGA were to come up with a similar shroud/fan/AIO, say a Corsair H100 that would be adaptable to multiple cards...

+1. awesome

Argh. Its threads like these that give me all the ideas.. 
 
Should had stick with Legos - they are cheaper. D:

Got to ask ,any chance using a lower profile fan you could put the shroud BACK on ? Getting the pipes to go out the fan hole should work .Just a idea

Very nice job done with this!

Well I'll be damned, that's quite clever...and useful. Great job!

I remember when pny released there AIO version for the 580 which kept the stock fan. The cool thing is that Dwood sells just the bracket without a fan attachment in case you are planning to use the stock fan which you can. If EVGA selled GTX 680 shrouds, I would have bought an extra shroud and made a custom cutout around the pump while using the stock fan.
 
I know that Xilence sells half width fans, but I do not know how effective they are.

not bad it looks cool

i would think even at half speeds(just a guess verses full size)  it would be enough to keep temps inside a safe zone even under a mild to heavy OC .Give it a try ?

this look amazing but what fans are you using on the rad. casue i bet with the right rad fans you can drop it even more... is tehre enough room to put small mem heat sinks on under the fan? and i hope he can make one for the gtx 660 when they decide to get it out.... just so people knwo i have sceen the thread at ocn he make brackets gfor some 400 and 500 cards... if you have not made your way to ocn go check out the link lotsa great pictures over there

Very neat; thanks for sharing.
 
Anyone else considering trying this, newegg has the kuhler 620 as a shellshocker atm:  $48 before an eight dollar rebate.

Thanks for sharing. Today wasn't a total loss, I learned something.

yup, totally doing this on my gtx 670 ftw!!!
