probably not. usually evga makes a custom pcb layout for their ftw models while the sc and ssc models are based on the original design. the vrms, mosfets, and memory chips wont be in the same spots so the block wont even fit or it wont be nearly as effective.
why would you want to water block such a low end card? there likely isn't a custom bios to circumvent the vcore limit and even running a 2100mhz on the core the 750ti would only match a gtx960 in performance.
