So I just finished building my first computer. Whether I'm playing games maxed out, I'm on my desktop, or I put the computer to sleep mode, the fans in my case are going pretty fast and I make a large amount of noise.
When posting, go into the bios using the "del" key; go into the hardware monitor section and look for "smartfan". Enable it; you may have to calibrate it first, then set it to "quiet" or reduce the fan speed to 50%. Some boards only control the cpu fan; for those, get a zalman fan mate series rpm adjuster or a complete panel with multiple knobs for more than one fan.
Well because you have an AMD Processor & Motherboard, you can probably use AMD's program AMD Overdrive to control at least the CPU fan. You can also use the program, Speedfan to control your fan speeds.
If the programs don't work, you can always buy a fan controller which shouldn't cost more than $30.
PG 2-15 in your motherboard manual, you can control the CPU fan with the BIOS or Conrol Center Utility you can get from MSI, you can also control a fan if it is connected to the sys_fan1 plug on your motherboard through the BIOS also, pg. 3-15. Or you will either have to use a type of fan controller or sofware(which may or may not work).
