If I replace the stock fan in my Xbox 360 with something quieter, would my console be flagged as 'modded' and hence ban my console, or live account?

This may void your warranty (for repairs), but will not be detected as a 'mod'.

Mods are considered to be any action or item that circumvents the built-in security measures of the console.


I have heard of this happening to some people. Apparently, the fan causes a greater (or perhaps fluctuating) voltage drop which the console detects and reports back to Microsoft. This can apparently earn you a ban, possibly because mods can cause the same sort of effect.

Instead of replacing your existing fan, can you use an externally powered or USB fan to blow extra air in? I can't remember if the 360's fan is temperature sensing but that might cause it to run slower.
