I'd say no benefit really. GPU depends on your case.. I'd rig up a 140mm just to test temperature differences to see if it's even worth it. I've never once had a decrease in temps blowing air with an extra side fan.
Then again I build with proper air flow always. In fact.... everytime I've tried it it increases temps as it blocks the original airflow by blowing air down at it. If you built your case for proper airflow a side fan is usually useless.
Haha yeah that Lian-Li is nice. Finally going all black with their cases heh.
Well going from the standard side door with a fan in it to the full window side door with no fan my temps went up 5 degrees. So I need to at least put a fan in there. I have every other fan slot in this case occupied with a fan so that is my only option.
I have heard from others that a fan blowing on the backplate of the CPU does help in some cases. A while back when I was trying to get past my OC wall with this 4930k someone mentioned to try that and see if it helps with the temps. Though to be honest my temps are normal if not pretty good for my low OC. I only qet 4.3 ghz on this chip as no matter what I do 4.4 ghz gives me a bsod within minutes of testing. But I am adding the fan behind the CPU just to do it. It may or may not make any real difference but I want to test it out.
OTH my GTC 980 OC's like a beast. I may not get the highest OC on this card but hitting 1558 mhz is pretty good for a stock ACX 2.0 cooler. I run it between 1507 to 1533 for normal games and it only hits 72 to 75 degrees on the higher end games. I have to lower it to only about 100mhz above stock for Ashes of the SIngularity otherwise it crashes the display driver.
