ask how you should best set up your case fans on the bit-tech forums and youll probably get around thirty different answers, each person swearing blind that his or her method is definitely the best set up.

With something like this: fan (push 25mm)+rad (25mm)+fan (pull 25mm)= 75mm cooler. I am curious to see if you can test a reversed configuration, where:
1. the rear fan is used as intake, the side is intake and top B fan is exhaust
2. rear+top (B fan) is intake
3. all exhaust fans (rear+top A/B) are intake and front turns into exhaust, side- intake

What you lose in CPU/GPU cooling by putting the second case fan in the front of the case, you would gain massively in reduced HDD temps.
Would it be possible to add an extra bit on hard drive temps?

I know it's what Corsair suggest in their instructions but in our H80 testing we found this arrangement made the GPU run significantly hotter, which is a poor trade off for the couple of degrees you'll save on your CPU.
