Sorry if that was a bit harsh. We both are feeling this in our own ways.
I also note that your criticism is with nVidia and not Dell. My apologies there, but Dell is the one you will call for replacement/repair and it will be their problem should your system go down.
I actually really like my laptop. There is a bowing out on the lcd bezel that is annoying and could collect junk in the bottom and of course I would have prefered 1G LAN since I move around a lot of big files. Other than that, I am really happy.
For me this is frustrating because when I use my laptop, I want to enjoy it. I want to enjoy games and now that is difficult since I am thinking there are a finite number of cycles I can go through. Each time I game, that number goes down. So while gaming, I am turning down options/settings to keep the temperature down and also not gaming as much as I probably would have if the problem wasn't there.
FWIW, 24 hour crysis sessions probably won't kill it. It sounds like cycling the system is what does. Load crysis, get to max temp, shutdown your laptop and let it cool down. Rinse & repeat. ATI tool also seems good for raising temps and if you *really* wanted to kill your laptop, you could (temporarily) stick a paper clip or whatever in the fan to keep it from starting up or turn it off by other means. I don't advocate that as an honest customer plus Dell could probably figure that out. Stick to cycling crysis/atitool and shutting down might be best (but take longer). Keep in mind you might never ruin your gpu (if what nVidia says is true in that only some are affected).
I am going to be an honest customer and use it as I normally would. If it fails, I will call Dell. If my situation doesn't warrant replacement/repair, I will buy a new laptop. I just hope I can forget about it more and enjoy gaming.
Temps: (i8kfangui with sensor swapped and 10C correction to match nVidia setting)
Idle: 65-70C (it is hot in Tokyo now)
Gaming (moderate games or settings): mid 90s
Intensive games: low 100's with 105C max
