I'm making a reply for the few who thought my thread interesting enough to reply...
Today, my PS3 hit the YLOD again, I was depressed beyond belief. I searched and searched for answers, then I found the most ratarded option to every dive into a PS3 owner's head. He put his MoBo in the oven! 
I had lost all hope, so i decided to do the same. 400F and 10 minutes later, I decied to place a different Thermal compound onto the cpu/gpu, and this time I would put a bit more than last.
I also had a super secret weapon, I would splice a wire from the fan to one from the PSU so that it would constantly blow at 100%...all the time!
My PS3 turned on! It's been over 7 hours and it is working great, not getting hot at all. I've played a few games, watched a few movies and it's still kicking. It is though, loud as fuck! I always laughed at those who thought the fan was loud at it's max speed, considering my PC has 12+fans. But, my god this thing makes my comp look like Helen Keller at the library.
