Well my ps3 is working at the moment. It took me two tries. The first time I reflowed it worked long enough for me to change my avatar comment to "YLOD Defeated!" before it failed ... about 5 minutes. I just did it again and now its working and has been for about an hour ... I'm cautiously optimistic at this point.

Some notes:
When I reflowed it the first time I was overly cautious. I added a lot of flux but then when I was heating it up I didn't want to get to close to the board so I was about 1.5 inches from the board. Plus I counted off the time in my head ... which means I probably had it exposed less the 20 seconds I was shooting for. After it failed I decided to be a bit more aggressive with my next attempt as I figured it was a reflow problem as it worked for a couple minutes.

The second time I kept the heat gun closer to the about ... about an inch and used my watch to count off 25 seconds. So far so good. I'm going to stress test it now and see if it can hold up to some gaming.
