Should be fine. The side case fan is mounted below the CPU socket, so it shouldn't interfere with the fan. Plus, that case is 9.1" wide. The 212 + is 158mm, 6.22", tall and 120mm, 4.72", wide if you want to double check it. I have a Scout case with a V8 and a lower 120mm side fan. That case is 1/2" narrower than yours.
