3.5 inch bay intake fan

[Woznet]

I have a 3.5 inch bay on the front of my computer that is currently being unused. Later this week, if all goes well, I should be getting my second gtx 670 for sli. With gpu1 and gpu2 being so close together I have been exploring cooling options to help keep temps in check. The external 3.5 drive I have, lines up great with the 2 gpu's inside the computer, I would like to use that 3.5 drive as an intake fan to help cool the gpu's. Does anyone know where I could purchase a 3.5 drive bay fan intake? If there is not one on the market, could I build something like that myself to work as an intake fan? Are there any alternative suggestions to help keep the gpu's from over heating?

Your case looks like it has 2 120mm fan mounts in the front, you could use either of those as intake.

I currently have the 120mm fan mount about the 3.5 drive bay with a fan, however directly inside of that intake are my 2 SSD's preventing good airflow to the GPU. I was thinking that moving those 2 SSD's to a 5.25 drive bay under my bd-burner, removing the part that holds the hard drive and put a more powerful intake fan there. Currently these are the 120mm fans I have installed in the case, I have 3 total, one in the front above the 3.5 drive bay, one on the top of the case in the back corner and in the back by the motherboard i/o panel. The case fans I have installed are - Noctua NF-P12-1300 120mm -. Do you think I should change out the case fan in the front or all 3 for a more powerful fan? Having the fans run quiet is extremely important to me, I would gladly spend a little extra for a fan that is going to run more quietly then something cheaper.
