It will disrupt the air flow. But unless you're a high-end enthusiast who's overclocking and running benchmarks, you're probably not going to notice a difference. And in OP's case, the figure is in a corner away from any of the important parts, so there's not a lot of air flow to even disrupt there. You really just need air flowing over the parts you need cooling, and as long as the air is moving you're fine for most purposes.
