I loved my FX cpu but I lived in a desert and the heat in the summer coming off that thing would make my room 100F or more. First machine I built a custom water loop for. Didn't help with the heat in the room, but did stop it from shutting down randomly, so I could continue to sit in the sweltering heat in my underpants and play video games until dawn. Better times.
Of course it didn't help the heat in the room, the heat from the CPU still has to go somewhere. Better coolers aren't for the room, they're for the CPU. in fact a better cooler could make the room hotter because it is removing heat at a higher rate from the CPU and dumping it into the room
