I might come into possession of a PS3 that has had the YLOD soon. My question is, how long does it usually last after the fix? I've heard anywhere from a few weeks to a few months. So, before I put all the time into fixing this thing potentially every few weeks, I need to know how long the fix usually lasts from someone who has already fixed a YLOD'd PS3. ANy other tips on exactly how to fix it would be helpful too. I'm already using a guide on YouTube, but if there any really important aspects of fixing, it would be nice to know them.
