I have a Intel Pentium Dual-core E2200 who has never been overclocked. My temps are running between 24°-41° when playing a game with high graphics. My fans use to be clocked up and i cleaned it but got a melting smell when my pc was running. Since i cleaned the cpu, and graphics card fan the smell is not present. But im paranoid that something is wrong. I use an external fan to cool my box down too. My temps look normal. Was this smell bc of the accumalted dust in the fans and is my system stable?
