We cook CIMs in drive practice, we're planning doing fans for the next season.
For the speeds we gear, in back to back elims we also get a little hotter than we like. We aren't failing CIMs, but it'd be nice if they were cooler.
There is also nothing inherently wrong with adding a 550 alongside two CIMs. Many teams avoid 775s because the widespread case shorting issues in 2011. It seems like they're failing at a low rate now, but many teams will likely never use them again.
Be a little less deadset in your own thoughts, and a bit more accepting of what other people are doing.

Only once in my FRC history can I remember killing a motor due to overheating, and that was a 550 used as a drive motor (the only drive motor on that wheel) in 2009 at the Waterloo Regional when I was with 1075. It was actually pretty spectacular, watching that robot drive around the field trailing a stream of smoke until the field crew made us E-stop it (the robot was otherwise operating just fine). I should have a look and see if I can find video. (Looking at TBA? I think it must be one of the 4 missing qualification matches.)
To me, the better question is why are you using 550's in your drive, particularly with the advent of the miniCIM and BAG motors in 2013?
