Fans make no temperature difference on HAF xb

Hello everyone. Its been a few weeks since I completed my first build with:

Haf xb
4770 stock fan
Gtx 780 (evga dual fan)
z87-HD3 (gigabyte)
corsair vengeance 8Gb (2x4gb)

I recently added a coolmaster 200mm to the top of the case, mainly because of the high GPU temps reached during gaming, which can reach the high 80Cs even with the GPU fans running higher rpms.

With front and back fans as intake, my CPU idled at at 31C. During rendering with 3DS Max, cpu reaches mid 80C.

I see no noticeable difference with the 200mm top fan, as either a intake or exhaust, and is disappointing/frustrating.

I tried changing directions, to every single possible combination that I could think of. Flipping top, front and rear fans. To me the most logical configuration would be front and back as intakes, top as exhaust, or front intake, top and rear as exhaust, but my temperatures are still basically the same, fluctuating by 1C-2C.

Room temperature is a steady 25C.

Any thoughts or ideas on why this is happening, or to how to cool my gpu more efficiently?

computer cases themselves won't really decrease cpu or gpu temps unless it's REALLY restricted.

in this case you'll want a better cpu cooler.
and a aftermarket gpu cooler

your flow must be front to back as show on the blue arrow on the link the front fac could be replace with two 140 mm one or get the 120mm one with a higher cfm so they will push more air in and if you could do the same with the 120 mm on the back http://www.coolermaster-usa.com/product.php?product_id=...
