Well, Yes, I think is better. And also the 92mm, anyway, will push the air against the cable and the PSU. But the 120mm is bigger, and take fresh air fully from outside. The bottom mounted 92mm has limit on that position
I don't realy see the fans push air against he PSU cables when using a g-unique PSU instead of a normal PSU. OK, there will be some cables in the case but not like when using a corsair PSU for example.
The intake, I can agree that bottom intake isn't the ideal situation, I'm just thinking about all the factors.
The EVGA GTX1080Ti FTW I'm using is a beefy full size card that doesn't leave any room on the GPU side where as the RXT Titan you are using leaves some spare room on the GPU side of the case and won't block air flow that much.
