So bought a new MOBO and a new CPU (I5 3570) and the cpu fan is on full speed (3000 RPM and it's loud). I can change it with speedfan but it's not permanent and i have to change it when the computer restarts. I was in BIOS and didn't find anything cpu fan speed related. I would like to change my fan speed to automatic, can i do that?

From your manual

"Hardware Monitor
Press <Enter> to enter the sub-menu.
CPU Smart Fan Target
Controls CPU fan speed automatically depending on the current temperature and
to keep it with a specific range. If the current CPU temperature reaches the target
value, the smart fan function will be activated.
SYS Fan1 Control
These items allow users to select how percentage of speed for the SYSFAN1.
CPU/ System Temperature, CPU FAN/ SYS FAN 1 Speed
These items show the current status of all of the monitored hardware devices/ components
such as CPU temperature/ system temperature and the few fans’ speeds."


Go to the hardware monitor and see what the smart fan and percentage settings are at.

You can set it in UEFI as explained in the manual. Just enter "Advanced" -> "Hardware Monitor" -> "CPU Smart Fan Target"
Note you have to temp set the earlier the fan will speed up.

Not in all the motherboards. Not mine! This is one of the first results when you search for "MSI 50% fan control" so Im posting for the next person like me to prevent them from wasting hours and hours.

Im on a H81M-P33 but this affects several versions of MOBO that dont have robust BIOS (yes I am on the latest rom) settings.

None of the answers above show how to set Sys 1 Fan to anything other than what it is showing (regardless of what it is).

The setting can't be moved - MSI needs to be taken to task for harming their own motherboards.
