Thanks wind and the rest. How would I go about blocking the hle where wing A is or should i just let air naturally raise up? Should I throw in one of cooler master's 140mm fans onto the back of hte heatsink instead of the ap-14, and then relocat the ap-14? Then I could use 2 wings up front instead of the silents for better CFM (and the top fan shouldn't overpower my silents, or I could relocate the wing to my side panel.

Windfire has the right idea in testing airflow.

When people have reported back from trying top exhaust vs top intake, their top intake results give them 5c better cooling. Mine was 3c.

The rear top exhaust tends to recirculate air from the top front intake, compromising the intake. OTOH, you could test it in exhaust, then blocked off. If the top exhaust wins, it's time for a new theory.

My thermostat isn't accurate enough for that, what would be the best way to block it off? I might be able to get my has on one though and put into my room.

(A) As for which fan (P-12, P-14, AP-14) goes into which position (front, med, rear) of your NH-D14, ehume should have more actual practical experience to offer better advice.
(http://www.overclock.net/air-cooling...-fans-d14.html)

(B) As for the Gelid Wing A, if it is used as exhaust, it is likely to induce 3 undesirable consequence (see pic):
(i) it sucks the already exhausted hot air (from rear Gelid Wing) back into the case
(ii) it prematurely removes air which is 'half-way through' the heatsink fins. This is not good because air is meant to travel the whole depth of the heatsink for optimal heat transfer.
(iii) its exhausted hot air will be sucked back into the case by Gelid Wing B

(C) If I were you, I will first try:
--Gelid Wing at Position D + Gelid Wing at Position C: these 2 ensure max green arrow
--Gelid Silent at Position B because its rpm needs not to be as high as in Positions C and D
--Position A covered up aesthically

As for testing, get any thermometer as long as you use the same one and leave it near your rig. Then test your temps with something like OCCT, which not only gives you a graph, but can be set to compile a csv file which you can average.
