NZXT Havik fan in the way of my ram

The stupid NZXT Havik fan is in the way of my ram. In order to install everything, the Havik fan has to sit a little higher than it normally would. How much do you think this matters and what can I do to rectify it?

It think it really matters much. You could try low-profile memory, slim fan, or just use one fan in a pull configuration. Personally, I'd just let the fan sit higher, or just use one fan in pull.
