Am I the only one not seeing the three images at the bottom of the first post?
I wonder how long your GPU will last?but I left the optical fan connected anyway. I probably could have safety removed this an reduced the iMac to 2 fans but I left it active and now cold air blows out of the optical drive slot on the side of the case.
Infact with the optical drive removed and the hard drive sensor running at only 1000rpm the whole system is general a few degrees cooler than it was at stock! Figure that out (less power draw from my new hard drive, optical drive removal allows for better air flow and SSD's draw little to now power and make no heat)

You would have to be absolutely crazy to even think about removing the OOD fan, it is the cooling system for your GPU. and by completely removing the ODD drive you have essentially reduced airflow over the GPU heatsink, you will eventually cook your card.
Good luck with that.
