xbox360 3ROD hardware failure got nothing to do with aircond lah. another forumer played his 360 in his airconditioned room and yet still kena 3ROD. the most important thing when buying a new xbox360 is to entitle for the 12months warranty coverage from microsoft singapore.

normally shop that you purchased from should help you sending back to msoft singapore for warranty but so far i only knows GH doing that for their customer. all other shops will not bother you at all after you paid them for the 360.
