I have some concerns about my box...It's about a year and a half old...Lately when i turn it on it seems like it is getting louder...Like the fan is getting really loud and humming louder than usual...I doubt very highly it is the power supply...Im running a Shuttle motherboard with a p4m266 chipset...Maybe there is extra dust in the back fan ? The motherboard is running at 108 degrees fahrenheit.. The cpu is at 80 degrees f...And my cpu cooling fan is running at 3000 rpms..Someone tell me if something may be wrong or if something is worth looking at thanx...
