No it is not needed. Some people like the fan mods but I'm not a fan of them - lol it was a pun I just got. I've heard some people say the fan mod can cause issues. I don't know how true that is because I've never experienced them but I feel I don't need fan mods. I think cleaning the system once in a while, replacing the thermal paste, keep it off carpet, and making sure it is an inch or so off the surface you have it on helps a lot. I use the tops on 2 liter sodas to elevate mine and it seems to help. I feel if the console is going to RR then it will. If it does it will need to be reflowed or reballed properly. That is key to getting a console back from the dead. Too many people attempt stopping the fans while the system is running to let it overheat. They don't get they're gonna mess their system up more than it already is.
