My laptop has been at about 120c and my friend's apparently went to about 200c and they're both fine :p Definitely not recommended, try and put it on a desk or even elevate the 4 corners so air can get below. But it should be ok
I'm having the same problem as you :S My cpu gets up to about 96 degrees Celsius, yesterday i thought it melted as everything stopped working, but it seems to be ok now, i hope. Will using a vacuum cleaner be more effective than blowing?
