My computer was unusually quiet today so I poked around and discovered that my power supply fan wasnt working. I have an Antec case with an Antec 300w power supply thats less than a year old. The case didnt come with a manual for the PS. It says on the side Smart Fan but I dont know what that means. I discovered this after an hour of gaming. Im suprised it didnt shut down. Im hoping this was a fluke. Ive repaired 3 computers where the PS went out and took most of the other components with it.
