Hello my first time visiting this forum. I have a athlon 2100xp it running 47c 116f which is very cool right now that i checked it but ive seen it scream up to 60c 140f. I had cleaned my puter out of dust which seem to be the major problem. is there airfilters for pc. This thing was only 5 months old and the insides were caked with dust. DO i need a new fan i only have 1 extra fan pumping out.
