I have a PS3 slim (the CECH-20xxA variety) and an E3 Flasher. I've been following this guide to try to install a CFW on my system. I installed the E3 flasher and briefly tried powering the system on to ensure everything was working smoothly. The system seemed to be fine initially. However within a few seconds the fan gradually started accelerating until the point that it was louder than I'd ever seen it. I disconnected power quickly to avoid damaging the system. What happened?
