Out of curiosity, why are those top fans intakes?
Of all the things to ask, you ask the least important question. But since it's you, I am not surprised.
looks like positive airflow to me. i see 3 in and i bet the rear is exhaust!
No.
I have found that high-speed ram degrades over time without cooling, Hynix and Samsung-based sticks equally so, even at "stock" 1.65 V. This is why those sticks over 2400 MHz generally come with fans, IMHO, and I think some company reps told me this, buty I cannot remember exactly who it was, now. I push way higher voltage than 1.65 V when testing, since DDR3 spec requires sticks can handle up to 1.9 V without taking damage(they don't have to work right for that requirement, simply be capable of booting successfully). That's why you see "extreme" guys pushing 1.85 V through their sticks, since most ICs still scale up to that voltage. The problem is that CPUs do not...still today. I cannot max out a few sets I have here on air. I've also killed more than a few sets of expensive ram recently, not just CPUs. The one set I really did not want to die...the one I use to test motherboards, one stick wouldn't even boot, and that set never saw more than 1.75 V when initially testing, and did 2933 MHz+ with 1.65V. I ran it for near a year at 2666 MHz, most often without airflow in my test-bench. Another set, my Dominator Platinum 2666 C10 set, it's degraded, but didn't come with a fan. Killed a few sets of Hynix MFR-based ram already too.
I was supposed to be posting a motherboard review every week, and between CPU and memory deaths, plus having my house flood, that's just not been possible. There's a few key people out there that work at these tech companies that have helped me out in a huge way the past couple of weeks, otherwise, I would not be back to doing reviews, this week.
Anyway, no fan on the ram, so the fans up top blow directly into the case, bringing a tonne of fresh air of the sticks and CPU VRM. Case doesn't ever have it's door on unless I moved it to where I might kick it.

I had an old LG W1943S for 3.5 years until a thief came and decided to break it. 
It was good too and it had good viewing angles but contrast and liveliness were not good compared to this one.
