Thermaltake V9 Black Edition + Zerotherm Fz 120 Zen

I currently have this extremely tall Hsf installed in a Chieftec Dragon case.

I'm not 100% on the clearance in my Dragon, but it seems like it was only a couple of centimeters, the last time I opened the case.

I'd like to buy this Thermaltake V9 Black Edition:

For the super sexy airflow etc. etc. I'm not a fan of their tool-less pci retention system, but there's really nothing stopping me from using screws.

What I'm worried about is the super sexy admittedly thin 230mm fan installed in the side panel of the case.

The V9 is only marginally wider than the Dragon. So unless the Dragon has the motherboard mounted higher than the V9 would, in terms of being closer to the side panel, I'm just afraid that the 230mm fan will interfere with my Hsf. I suppose I could always just remove the 230mm in the side, considering the design of my Hsf. I question how much good a fan blowing air into the case could do.
