Hello guys, something happened with the light of the power button. I don't know if it is a pre-YLOD sympthom. After I exploited my PS3 and I installed Ferrox 4.83 CFW, I configured everything that I wanted. Essential APPs like Managunz, File Manager, PSN Patch, Control Fan Utility, OpenPS3FTP Plugin, Retroarch were installed. Then I transfered (openps3ftp-ntfs plugin and filezilla) 1 ps1 game, 1 ps2 game and mame and console roms collection with all of respective thumbnails from liberetro to use with retroarch. It was a lot of files and my PS3 worked for hours. I split this activities in 4-6 hours breaks. Here we are in the summer (and this week was very, very unnusualy hot) and between this transfers I took a look at the Control Fan Utility and it displayed almost all the time temps between 50-60 celsius for both cpu and rsx. Once it got 71-72 celsius and temp text started to blink in Control Fan Utility, so I concluded that it was a warning. And because of that I started to take some breaks (and turned the air conditioner to a very low temp, 17 celsius) because it was many, many files transfered to my PS3 to get it all configured for retro gaming. The next day I concluded the rest of the file transfers and hours later I decided to give it a try. I powered on my PS3 and started to browse PSX-Place and other bookmarks through the Web Browser. After that I returned to the XMB and before I tried to open Retroarch I have realized that the light of the power button was changing gradually from green to white, like a gradient. I took a close look and between these changes, it looked like the yellow color appeared for a brief time and then it turnt to white and then again to green, etc. A very soft transition from the colors. I got worried and checked the temp at the Control Fan Utility, it displayed about 71 celsius for CPU and RSX and it was blinking (like a warning). I turned my PS3 off and waited for 15-30 minutes. This time I turned my Air Conditioner ON (it wasn't). I turned my PS3 on and waited for 5 minutes or less I think, and the same light behavior was happening. I checked the Control Fan Utility again and the temps this time was fine, something between 50-60. Then I tried to change the speed from PAYLOAD to mode 1 (maximum speed) or mode 2 at some speed like 90 or something (don't remember, but it was faster than default), after this settings the light behavior was gone, the color was an intense green. So I tried to change to PAYLOAD (default speed?) and the light behavior was back. Any thoughts? Is it normal? Am I good? Any advice? What are the maximum temps for PS3 (the safe range) and what temp should I worry or prevent to not pass that? My PS3 is Slim CECH-20xxA (late 2009).
