In my Fractal R4 with an H100i, when I had that case it was a very tight fit. So tight that I could only get it in if I installed it first.. so what I did after everything was already installed, instead of using the 120mm holes, I just used the actual grill holes. It worked out for me. I was able to move it closer to the left of the case which allowed me enough clearance over the motherboard vrm heatsinks instead of risking bending it.. Could try that?
