yeah, the no fan idea is like having a vehicle with no antifreeze....baaaad. oh and a way microsoft can check the fans is by clocking the fan speed. the xbox 360 holds records of how fast the fans are spinning. say if i chip it, then the chip gives me a system info screen to where i can check/change the fan speed. the programming is in the xbox 360, just not accessible without a chip to bypass everything. thats a way they can check. It's a ify question, but i believe its possible, and i figure i would have about the same chance of getting caught for pirating music as i would for putting fans in... yet there still is a chance i can get caught and i dont want to have my account that i spent alot of time on get banned for sumthin dumb that should be fixed anyways. why have that happen when i can put sum nifty fans in that keep my xbox 360 at room temp and my nerves at ease?
