Hello all, love this site. So my question today is about my fan setup, I currently have 2/120mm intake fans down front and 1/120mm exhaust fan out the back in my Rosewill R5 mid atx case. I also have a Hyper 212 evo with a 120mm fan in line with my exhaust fan. Im getting pretty good temps, CPU idle 33C-load 46C; GPU idle 30C-load 57Cish, but wanted to shave off a few degrees off those temps. I plan to side mount a 140mm fan intake aimed at my GPU, and a 140mm exhausting out the top of the case. Is 140mm overkill, or a good idea? Will this setup give me superior airflow to what I have now?

-I wanna get 2 of these fans: http://www.newegg.com/Product/Product.aspx?Item=N82E168...

I would vote on the 140 intake and exhaust like pictured, but the fan on the EVO needs to be on the other side, you'll get much more direct airflow over the fins that way.

Funny you should mention that, a friend who supposedly knows pc's, told me to move it to its current position to draw cool air through the cpu cooler. I had it pushing air through originally, I guess i should move it back then?

Definitely. When it's pushing (on the opposite side) you get direct flow of cool air over the fins. When it's pulling (the way you have it now) it's pulling the air from the sides as well, so not as much direct air flow. That change alone will give you a little better cooling.

thanks, I'll try that tomorrow then! Btw, I assume that the arrow on the fan points in the direction it pushes air, correct?

Temperature and airflow is a funny thing, there are too many variables in play to empirically say which setup will be best so it is generally best to experiment to find which one is best, or simply just find one that is satisfactory and move on. Generally you don't need the best possible airflow, good enough will be good enough.

Yeah, the arrow perpendicular to the fan shows which direction the air is pushed, and the arrow parallel to the fan shows the direction the blades are turning.
