Hey guys i recently upgraded my computer and got a GIGABYTE GA-78LMT-USB3 AM3+ motherboard and FX-8320 CPU. I got everything up and running today to hear a very loud noise coming from the CPU cooler. I though eh its just gotta do its thing at first but no. i only have the internet open right now and it is running at 4.5k rpm. I tried to look for settings in the bios but i couldn't find anything to help. Any help would be greatly appreciated.

The CPU fan is plugged into the slot marked as CPU fan coming from the motherboard

go into your bios and set the the fan speed to medium. If you find that your temps are too high you may need to clean and reapply thermal paste.

I said in the description that i cannot find any settings in my bios to change my fan speeds.. And my temps are fine. Its only the CPU fan speed.

Here is i think the correct tab of my bios to change my fan speed but it just goes from auto to disabled. http://prntscr.com/2jf1a0
