Its probably normal, what do you have 60Gb?
I read about this somewhere else on these forums.
Think of it as a bonus, you now have a fan heater for those cold autumn night sessions.
I have a refurb 40GB.
mine does the same, play uncharted for about 20mins fan kicks in, but stops the second i turn uncharted off lol
Better than toasting the ps3, isn't it?
Facts of the moment:
"My PS3 is not fat, it's just big boned."
"The console war is as real as the war on terrorism."
"The wizards first rule applies to both YLOD and the SLIM."
"Tons of trophies doesn't say you're a great gamer, it says you have too much free time."
