I had some doubts when buying this thermal paste that I had heard the most good. But following the YLOD occurred on my ps3 FAT I wanted to try the repair (temporary? Because a Ylod always ends up back in after a while) and it worked, nothing very complicated and this dough does not cost expensive!
Finding a great product that I highly recommend for computer problems (overheating) or to repair your Ps3 after a YLOD (repair can take from 3 months to 2 years, which is long enough to recover all your data and transfer them to a new PS3!)
