A dumb question, sliding the bottom fan to it's lowest position in the front, will that make any difference over it's current position (in the picture below), to the GPU itself?:
Nah, just thought that more of the fan itself would be more centered towards the GPUs fans.
For looks, it would look a bit wierder pulling it down, since it will then be a gap between the top and bottom fan (cause the top mounted one can't go any further down unfortunatley). If it could, this thread wouldn't have been created since I would then just have pulled them both down
