How many times does the same thread have to be created, isn't there a search feature for the forum?

You raise some interesting points, particularly the first two I've highlighted.  You're definitely correct when you state that the issue is the 360 simply ran too hot (my second 360, which I purchased this year runs much cooler), but questions such as watching streaming movies, etc., are designed to determine what heat might be generated by specific usage patterns.  If you hook an ammeter up to your 360 then play games, watch DVDs, watch streaming movies, etc., you will discover that your 360 draws different amounts of current depending on the activity, which in turn generates different amounts of heat.  The duration of use can also determine heat build-up, as you have implied in your post.  Orientation of the console may affect/constrict air-flow as the case has specific air-intake points, and the intake points used can also affect how air will flow across the components.

Regarding a problem with air-flow across the console using fans, this is something I've never heard before.  The general approach to cooling electronic equipment is to have fans or convection currents vent the heat from inside to the outside, and then to have plenty of airspace/airflow around the cabinet to pull heat away from the unit.  This is all to prevent heat buildup.  I suppose it's possible that pointing a fan directly at the output vents in back could "fight" the internal fans trying to force heat out, but a fan pointed at the front of the cabinet should aid in cooling.

As an aside, it's refreshing to see a girl/woman in the forums.  They're far too rare around here.

I keep hearing that this has already been done before.  If so, was the previous attempt(s) as comprehensive, and can you point me to it(them)?

Thanks to everyone who participated. I'll try to dig up the older things several posters have referred to... and I hope we'll have any more participation before I start analyzing what's in here.

I have had two RRoDs...

None within my home...

The only time I have received them is I took my 360's on trips to places. One happened upon arriving and turning it on. The other started freezing on the trip and failed when I got home...

To me, RRoD is a none issue in controlled environments... I have 7 360's.

Lol, it sounds like the 360 is better of not being used under common circumstances. Basicly everything you do is wrong
