Intercooler EX?

[DocHoliday]

I'm seeing conflicting reports about this, so I'm hoping to get a more accurate answer here:

Does the EX (not the old 360 version) work?

I keep reading things about rails, how the power stolen puts strains on the components, or how the fans work against the 360's own fans and eventually crap out everything, etc.

Are any of these true? I've had mine for about 4 months and haven't seen anything bad happen to my 360 so far.

My 360 does seem noticeably cooler, but again, that may just be me trying to justify my purchase.
