Wow, that is quite impressive! Wish I could afford to sli two titans lol...
I was thinking the same, put the hybrid on top. Plus I have two 120mm corsairs pulling air in the left side directly on the GPU, so that should keep the regular ACX card cool, as it only gets up to 56-62 C with the current setup. I will look into the hybrid kit as well if I'm not happy with the temps after I install the sli.
I have read the various issues running SLI, plus some games are not even compatible with it. Do you think it will improve in the near future?
Thanks for the advice man, I really appreciate it and will definitely keep you posted. Funny avatar btw! :D
