1st gen PS3, got the YLOD for the first time a few days ago and followed this guide. Took me about 3 hours but now the PS3 is back up and running beautifully again. I was totally skeptical about taking a heat gun directly to a CPU/GPU but thought I had nothing to lose and it worked! Kids can watch Netflix and play games, everyone’s happy. To apply the thermal paste I used the guide mentioned in this article, using a plastic bag to spread it evenly with my hand. Instead of buying the kit, I just bought some thermal paste (with remover and primer) and thermal pads on amazon, cost about $20.
