Actually the fan kit does not direct air to the areas occupied by the graphics and VRM cards, but is physically separate from them, so it is really only good for a processor upgrade. Essentially it only succeeds in expeling air from the large CPU vent in the centre of the case, but not from the video card vent. The VRM card is right underneath the latter vent, and it is this whole area that especially needs better ventilation. One solution is a fan on the video card itself, drawing air up from below and out the top; while another is relocation of the VRM card (which is the best solution as far as cooling it goes, without a doubt); I think my solution, however, is also reasonably elegant, and it is probably easier than any of the others.
