I have an ASUS motherboard that shows me my temperatures and all that and my cpu temp is low, but the fan is going at 100%. If I turn off BM the cpu fan stops. I have the ASUS monitor and it shows me that the temp is low and the fan should just be nice and quiet and hardly being used. What can I do to change this? I can't find a place to post the photos of my CPU fan settings on here. If someone would like to see them I can email them or something.
Thanks

You should be able to set in your motherboard's BIOS/UEFI what level all the fans in your system should run at from startup.

When your CPU temperature is low, it may be that the GPU is being used.
Running BOINC will put a load on the system, be it running work on the CPU or on the GPU or both and when these are under load they get hot. To get rid of that heat, the fans will spin extra.

There are plenty of programs available to stop the fans from going wild, even under load.
I pretty much like http://www.almico.com/speedfan.php because it allows individual setup of all the fans it detects, CPU fan, Auxiliary fans, GPU fan(s) and even the PSU fan if it detects it.
