I'm so paranoid about RROD, like most people who buy cooling fans. First off, let me say that I keep my 360 in an open, cool, ventilated environment. Right now its 58 degrees outside and I have the windows open with fans in them, and oscillating fans blowing all over the living room. On hotter days, I keep the AC on about 60, so its always cool when I'm playing the 360. But, I fear that a cool room is not enough, and I want to have maximum heat dissipation/airflow. So I'm going to buy a cooling fan, and I've been looking at the Whipser Max, because of the size of the fans. It is internally powered thru the 360's power, which I've heard is bad for the PSU, which could end up screwing up and giving me a RROD. I haven't seen any externally powered cooling fans, only talk of them. My question is, which is better for the 360 as far as not causing RROD through heat issues, only because of the fan itself and the way they're powered? Internal or External?
