Any way to quiet my 360?

Food?

...without voiding the warranty, that is. And as cheaply as possible.

I don't remember it being this loud before (it's standing up now), but I've been playing Halo 3 a lot and the noise is atrocious. Is there any way to quiet the thing down without having to open it up?

Keep it as ventilated as possible to prevent the fans from reaching warp speed. Other than that, I think the answer is no.

I've noticed that my 360 makes less noise when it's placed vertically.

Get an extra long video cable and put it in a different room. The pads are wireless, it should do the trick!

(This is actually a semi-serious answer, there's no way of quietening it short of opening it up)

The placement and the room your 360 is in will affect how the sound resonates dramatically. Like I have hardwood floors, thus sound tends to bounce around a lot in my room rather than get cushioned if I had carpet.

The problem is, sound dampening and ventilation don't really go hand in hand. People use pieces of carpet and such to dampen subwoofers in apartments, but you wouldn't dare do that with a 360. If your 360 is in an enclosure, it might be amplifying the sound - like yelling through a cone.

There's so many variables, but basically trying placing it in different parts of the room. Also, you might get some large rubber o-rings and try using them to stand your 360 on. Maybe even a padded surface underneath, like thin foam or carpet. Make sure the spacers are large enough to offer ample airflow under the machine, though, or you'll overheat it pretty quick. I noticed a pretty big difference in sound when I got a computer case that used rubber grommets to hold the hard drives in place, for example.

Even doing that may not make a difference if it's just the fan blowing away. But if it's that big a concern, worth a try as it's cheap and easy.
