NZXT offers the H9 Flow in three versions. The first is a $169.99 base model (no “RGB”) with three ordinary fans up front and one in the rear. Our $209.99 RGB test model comes with three RGB-equipped fans up front, but uniquely encased in one combined fan “unit” (more about which later) that NZXT calls its RGB Core Single Frame design; the rear fan is a single RGB spinner. Last, a top-end RGB Plus model ($289.99) includes a second RGB Core Single Frame triple-fan unit on the case bottom.
