So this is the first time (for about the past week) that I've heard my mobo's fan making a pretty noticable noise. Upon inspection it seems like the fan is spinning, slowing down, speeding up, slowing down..etc... Not sure what to do (and whether or not to start panicing). The system is a Gigabye GA-7VAX with the KT400 chipset. The fan is directly on the chipset so I definately don't want this baby to die. Any ideas?
