I would expect the fan to run more frequently if the PSU was oriented with the vent facing downwards as the heat would just build up, requiring air flow to remove the heat that is unable to naturally escape upwards like it should be able to with my setup.
From what I read in your post, it sounds like you have the psu's fan air flow turned round. That fan is the psu's intake - the ventilation on the rear of the psu is its exhaust. My X-850's fan spins up only when I put a load on the cpu - gaming. - or when the ambient temp goes above 77f. So your graphics card isn't going to be pulling heat up from your psu - even when the fan isn't running. Your case has 2 front fans intaking cooler air that will hit the graphics card intake fan - with the psu fan not spinning, that just means the graphics card is getting more of the incoming air. If your psu fan is not spinning, try switching the psu cooling switch to normal - that way, your psu will not run in fanless mode - it will then be intaking air either in silent mode or active cooling mode. Set to normal or hybrid, it takes an ambient of 25c [77f] to spin the fan, so what heated air there may be is going to be far less than the front incoming cooler air. Also, that's a good reason right there to flip that psu so its fan does intake cooler air from beneath the case.
I take it that your case is desked - easier to keep clean, less dust and hairs and crud than when sitting on the floor.
To my way of thinking, the psu fan intake and vent exhaust is a separate entitiy in the pc case - there is no benefit of having the psu fan - an intake - pointing to the graphics card, other than aesthetics, imho.Warning: Spoiler! (Click to show)
That is a nice w/c build, esp if its the first. I just built my first w/c into a Switch, and I wish my buddy had allowed for putting water onto the graphics card. Nice !
Very clean, too - sleeving would only add to the looks, but that is a great looking build.
