How do I control my system fan?

My specs are below and my fans are all daisy chained together and plugged into the system fan port on the motherboard. I have speedfan and thought I could do it there but can't figure it out. Any help would be greatly appreciated.
 
boot computer up F1 or one of the F* keys into bios then go to hardware monitoring aka system health settings. From there select fan profile change it from auto to standard and that will monitor and change the fan speed according to the temperature of the cpu.
 
Thanks for the quick reply but I would like to speed up my fans a bit manually instead of doing it by temperature. Would I need to buy a fan controller? And would a single fan controller control six fans if they are all hooked together? Thanks

it is nice to have a fan controller. are your fans molex or are they hooked up to the motherboard?

this is the fan controller i have:
http://www.newegg.com/Product/Product.aspx?Item=N82E16811995016&cm_re=sunbeam-_-11-995-016-_-Product
up to 6 fans with up to 30 W for each fan.
 
If your fans are plugged into the motherboard you should be able to control them with a program like speedfan. If they are plugged into molex you could just undervolt them.

Before changing the speed, I would change how you have them connected. Having several fans on 1 header is a bad idea because you can easily overload them and cause damage to your motherboard

Like mentioned, speedfan is your best bet. download from here:

and once loaded, the bottom left of the window it has your fan and a % of the speed. Just drop the % and your fan speed should decrease too

The only other way is to get yourself a fan controller. Your fans plug into it and each 1 has a knob which controls it. Turn it down to slow the speed, or up to increase it.
 
The fans are hooked up to both molex and the motherboard. When I boot my pc without it hooked to the motherboard my computer beeps telling me there is a problem.

There will be a setting in the BIOS somewhere to change errors, and whether they are displayed and make POSTing fail. 1 will be system fan or CPU fan. If you set it so that it doesn't cause system POST failure, you won't get the beeping any more
