I'm impatiently waiting for F1 2012 to download, after getting my force feedback wheel working, and playing the Dirt 2 demo. I have an old Dell laptop dock, that was designed to have a CRT monitor sat on it, and it gives me the perfect setup, with the wheel clamped to the table and my rMBP sat on top of the dock just behind it. It made me think. Running the Dirt 2 demo had all the fans on, and even with the power adaptor attached, I still lost 4% battery over an hour or so. So, would it be wise to employ some additional cooling, if I'm planning to do regular full length grand prix? If so, what would you recommend? Thanks.
