I just completed my new build and turned on the computer. The fans were super loud, so in the BIOS, I set the fan speed to automatic and then it prompted me to set the temperature, so I set the temperature to level 7 (50C/122F). I'm just wondering if this is safe, because when the fan is at 100% at level 10 all the time it is really loud and annoying.

One possibility that I've heard is that the CPU always runs at 100% in the BIOS and won't under clock itself when not in use to get lower temperatures.
