Are fat models guarenteed YLOD?

I still have my 80GB PS3 and it's still fine. I did upgrade the Hard Disk to 320GB (because of all the stuff I save on it). To be on the safe side though, I also threw in a 3rd party system cooler (the one that attaches to the front where the ventilation intake is and is powered by the USB ports).

It seems like the bigger models would offer better cooling. I wonder if those getting YLOD are running their PS3s for hours on end. I don't usually do that for anything so assuming I used a fat model for a reasonable time and kept it in a cool environment.. could it potentially last as long as a slim? That's all I need to know.

First 60gig - YLOD

Referb 60gig Sony gave me - YLOD

Reflowed this summer, month later - YLOD

Reflowed again, waiting for the light. Loud fan.

I've never had any console crap out on me before in my entire life, from my Atari 2600 to my (now ten year old) PS2 and Dreamcast. I may like the PS3, but as far as I'm concerned, it's a piece of unreliable crap.

Let's just say that i've owned my Phat boy 80GB PS3 since launch and i have never had an issue with it. Still runs like a champ and i barely even clean it.

i got an 80 gig phatty during the last run about 3 years ago and it seems to be working fine.
