ive been looking at your card Khalam and its still possible but not with retaining the shroud. Its just a thin metal wrap coving the heatsink. Both fans are hooked to the heatsink with three screws each. Removing the heatsink removes both fans. Its pretty much the exact same thing as my Zotac 560ti in design if compairing cooling fan mounts. Now i ran the fan off/fanless and the card and hit 1275core, never an issue, card still works to this day. Now its just a 250 dollar investment for me, not much of a deal but your cards are fantasticly more expensive. Mounting the pump is not an issue, they are the easy part in this mod, serious its like 5 mins complete. Choosing to cool the pcb will take some more time depending on how you want to approch it. My suggestion would be to run the card with two side mounted fans seporate from the card blowing in towards the mobo and on to the cards pcb. This will still generate much more airflow than what would hit the pcb through the heat fins. This is how my 560ti was.
Here is a pic of what i mean.

My window is solid and does not allow for fresh air intake. The air the two 120mm blow is just case air but that is all that would blow anyways if your using stock card cooling
The second option is to mount a 120mm fan right to the card. Like layed down flat on the top of the pcb and attached with zipstraps.
Here is a link to how this fellow did his card....
Viper522, now obviously he has a heatsink before the pcb where you will not have one, just a fan on the pcb.
From what i have experianced and seen/read you dont really need a fan on the card blowing, the components are going to be fine without it. But that is not my call to make but i know it was not needed for a 560ti at 1275core.
For the matix and my zotac i was luck in the fact the shrouds got to say but id do the mod anyways for performance gains and the lack of noise afterwards.
Lets us know what your thinking after you read this.
