Hi, Im new to the iFixIt Community. I myself had the YLOD on my PS3 CECH-A01. I didn't use this guide, but its similar to what I did. Heres a few tips. MOD YOUR CASE!!! Cut a hole using any can and heat it up on the stove. When hot place it on the center of the area where the fan is and let it melt on threw... Provides airflow into your system to keep it cool.. To cover the hole, use a 6 and a half inch car speaker cover to make it look nice. UPGRADE YOUR POWER SUPPLY! The 231 unit runs much cooler than the factory installed one. Also, cut 4 holes with a drill on the side where the warranty sticker is to allow the hot air to escape more freely. You can cover with a screen that you can buy at a smoke shop... UPGRADE YOUR FAN TO A 19 BLADE FAN! Provides max airflow throughout the system. Get some 1.5 inch rubber pegs and Crazy Glue them to the corners on the bottom case to allow air into the fan hole. I heated my board in the oven at 300 degrees for 10 to 15 minutes. It works!!! Good Luck...
