    I've recently bought a custom built MSI 790FX-GD70 and the fans on the machine are always blowing loudly from the moment I turn it on. I've tried setting the fan speed in BIOS, using the Speedfan software, to no avail. The PC has about 5/6 fans, but I think the top fan is making the most noise.
    Is there a way for me to control the speed of these fans, and have it quiet (dead silent)?

    According to the motherboard manual, Page 3-16, there are settings in the Bios to set the fan speeds.

    If you don't have the manual you can download it using this link :- http://download.msi.com/archive/mnu_exe/E7577v1.0.zip

    It's a PDF file so you will need a PDF reader program to read it.

    I tried setting the fan speed in BIOS, but nothing changed. The guy I brought it from said the fans where controlled via some knob in the case, but I see no knob to control the fan to low/medium/high.

    Looking at your picture again it looks like the fan only has 2 wires leading from it, to control the speed you need a fan with at least 3 wires, so your only option is to disconnect that type of fan.

    You do understand that the motherboard is almost 10yrs old. The processor is about the same age; almost 10yrs old. Are these new parts or used?
    You are using a stock amd cooler which can get somewhat loud IF you are attempting to overclock. If you are running at stock speed, then the stock cooler should be fine.

    Speedfan is next to useless. It was a fine program in it's day however that day has long passed. Check the fan lead and see if it is a 3 wire, 4 wire, or 2 wire fan. It should be a 3 wire fan however with parts that old, it pays to check.
