I just installed the Cryorig H7 with Arctic Silver 5 Paste. First start up I had the fan speed on Silent(low) in BIOS. I restarted and the BIOS said "Fan Failure", and the computer froze. I went into BIOS and the fan said 400 RPM at 30C, and it was in red lettering.

I switched to "Normal" fan speed in BIOS and the fan went 600 RPM at 28C.

Then I switched to "Turbo" fan speed and now it's at 720 RPM at 21C

Is this normal? I've never experienced such low RPMS before. I'm scared because I don't want my computer to blow up or something.

(AMD FX 8320 and ASUS M5A99FX Pro R2.0)

Typically, the only component in danger of exploding is the power supply and that's usually only a problem with very low quality units such as Logisys and Raidmaxx. Even then, it's unlikely, especially if you aren't overloading the power supply. Just to be sure, what PSU model do you have?

Your fan speeds and temps are low, but that's partially because you're just in the BIOS where processor utilization will be very low. Try booting into Windows with the Turbo fan setting and watch fan rpm with a program such as Speedfan. If your temps aren't getting high, like over 60C, open up a more intensive program like a game if you have one and see how the temps go. If they get dangerously high, then the CPU should throttle to keep them lower and worst case scenario, the board should force a shutdown to cool off.

I have a Rosewill Gold-rated 450Watt PSU. My computer has been on for a while. I play Call of Duty: World at War, watched some Youtube, and surfed the web. So far:

Min: 421 RPM @ 27C
Max: 778 RPM @ 43C

I finally found out why my computer froze. There's a minimum limiter that was set at 600RPM. I set it at 400 RPM and now it boots fine.
