Despite knowing that you can't kill a PlayStation 3 whether you play it in the back of a freezer van or a heat sauna, Sony still takes it to the next level by incorporating the 65nm Cell chip on the new 40GB models. (They probably aim to make it nigh indestructible.)

The addition of the Cell chip lets the PS3 reduce its power consumption, bringing it down to 135 Watts from 200 Watts. The console then runs cooler and quieter, which as any gamer who plays for an extended period of time will know is always a good thing.

Aside from the Cell chip, the new 40GB console insides (as opposed to the recent comparison of the outside) have been considerably tinkered with (in a good way, to be sure). The heat pipe is smaller and the motherboard has been changed with a new version, which now has a battery to keep the system time when the console is off.

It's been reported way back when that the 65nm Cell chip would land on the PS3 (it just landed on the Xbox 360 first is all). It was also expected to land on a new PS3 model with lower manufacturing costs (which the 40GB console definitely is), which may suggest that plans for a 40GB console may have been in the works as early as then.
