Alright. I was just asking to see if I should use a certain fan I have in hand right now or not, or I should buy another fan.
This is what I was planning to do. I found this picture on Google, and thought it was a nice idea.
However, I recently bought a Scythe SlipStream Slim (120x120x12, 45 CFM, 37 dba). I originally planned on using it for my Hyper 212+ heatsink since a regular size blocks one of my ram slots. However, it didn't perform as well so I took it out. I figured out a way to mount the stock Hyper 212 fan back on, and now it works. However, now I have a Scythe SlipStream Slim that is just sitting there. So I am debating if I should use the Scythe to put it where the Google picture has it, or if I should buy a regular fan that has higher CFM. Noise doesnt matter as I will be using a fan controller.
If the temps where to change about ~1c-2c difference between a 70 CFM fan and a 45 CFM fan cooling the graphics card, then I will just use the Scythe. But if its more along the lines of ~5c-7c, then I will consider it.
