Hi so around 2 weeks ago, i decided to get an Xbox 360 slim and i noticed it gets really warm when i feel the vent. I was playing Black ops for maybe an hour? and then i took it out to play some halo reach and it was really warm so i felt the vent. It was extremely warm after an hour of gameplay(roughly 45 min ish) Is this normal? I put it in like 2 level shelf tv table but when i play, i always open the glass frames. Do i need to get like a cooling system or is this ok?
