Duno bout it but for the first time my 40gb kicked into full speed fan mode when playing gta iv on a hot afternoon day, graphic glitches start occuring, i quickly turn off the ps3, thankfully nothing happen after that * touch wood * and it seems that 40gb are getting more and more ylod cases, better start take caring of mine better

Lol pretty much useless i think, cause from what i experienced with my laptop + a laptop cooler, it actually cause more overheating than cooling as the heat tends to clog up at the bottom of the laptop cooler, the fan blow up more hot air as times goes, don't know whether its caused by my cheap laptop cooler or what, haha.

Anyway, the ps3 did a pretty good job with cooling already, so u are pretty much pissing in an ocean of piss Just put ur ps3 into well ventillated area, its more effective in cooling it off
