A:Answer We've only had it about a month, but I have not heard any fan noise, however temps in the house have not gotten much above 70. Also, it only does light duty (mostly internet) so the CPU gets very little strain. Perhaps if your applications included video editing or intense gaming, you would hear some fan noise but for us it is not a factor. The Windows XP "tower" computer it replaced was much louder and threw off more heat.
