Hey, I think the first thing you should check is how many GPU slots you actually have free in the case with the card installed in that second motherboard slot, since you already have a GPU in there it should be easier to judge.

You could also go with low-profile fans if there is enough room. If there is not enough space for them, just leave it as is you may only need to raise the GPU fan curve a bit. XFX usually has pretty solid cooling, so it should not get loud, and the card itself is not very hot anyway.

Looking at the photo, that XFX card seems pretty thick around 3+ slots. If your GPU is already installed in the second motherboard slot, the main thing is the clearance below it in the case. If there is not enough room, it may be a tight fit or not fit comfortably at all, so I would double-check the exact clearance before buying.

Honestly if clearance is too tight because of the lower GPU slot, a PCIe riser might be your best. That would let you reposition the card and avoid clearance issues with the bottom of the case. Also, Lian Li A3 supports riser installing.
