Advise on properly cooling a Galaxy 660TI 3GB Card?

[Nate86]

Hi guys i know i'm going to get flamed on here but will 5-6 Corsair Air Series AF120 CO-9050015-BLED 120mm in a mid tower case cool my Galaxy GTX 660 TI 3GB card that much more than the good cooling on it im venturing out to 3D rendering and for my gpu to be going on for hours on end i want it to be like 5 to 20 C if thats possible on full load and under my assumption i always thought that how you cool a card is by the actual fan and heatsink underneath that is your gpu/core mosfets etc is that true or is it your hole card temp that it goes by using msi afterburner of course and will it be also better for overclocking as well if i have a lot of fans in my atx mid tower case and does more fas equal better overclocking of your gpu and if so does increasing your core clock help reduce rendering time thanks in advanced and i apologize for my bad spelling and grammar.

full load on that temp with air cooling? i don't think so. even liquid cooling will have a hard time (but i'm just assuming)
gpu's can tolerate high temps. just know the limit and don't let the card hit it.

add your fans, do some cable management. hopefully the room the pc is in has decent temperature, and that your case is not that cramped.

if you OC, then that will increase the temp which goes against your target but will help in rendering (provided that what you use takes advantage of it)
