I have Slim PS3. I hear small noise in the console when turned off. I think this noise comes from the fan. I don't feel air flow when I hold my hand on the air grille. My console works smoothly and quietly while playing games. My console doesn't go above 60-70C°(WebMAN Mod) degrees when playing GTA V for long periods. What do you think is wrong? Will this problem cause problems in the future?
