You can swap the coolers but you'll have to find some one selling an ACX3. It won't happen this time around but I still have my fingers crossed that EVGA will sell an ACX3 so I can air cool a Titan XP.
Not really The PCB is Smaller than the FTW that uses the ACX 3 Cooler, their is no way to Mount it.

mojoeman265 Can you Post a Photo of your Computer with the Side Cover Off so we can see how your card is Mounted.
I have two Reference Cards with Blower Style Cooler and while I run up as high as you at 83C my Cards are running 7x24 @2025 MHz and the temps float between 67C and 78C.
I have OCX Set to 124% and the Temp Set to 86C. The max for the Card is 92C
