My computer is very loud, I have 2 LED 120mm fans which use 3-pin fan connectors and I can have them at 50% - 100%. I also have a molex 120mm fan and 2x molex 90mm fans and I can't control these molex fans at all. I have a very quiet CPU cooler, no GPU and my PSU fan doesn't spin at all until it needs to and my PC is very loud. What should I do?
How do I turn down the fan speed below 50%?

Your best course of action would be to replace the fans with PWM ones (if your motherboard has 4 pin/PWM connectors) or quieter ones.
You could get a fan controller like the Bitfenix Recon which I use.
If you need a quieter fan to run at max speed all the time, look at the Noctua NF-F12 or S12-A fans

One other thing to consider. Some fans will simply not turn down to 50% or below. They will run max 12v, min 7v, and simply stutter at 5v, which is the 3 voltages on Molex connectors. Best advice, do some reading up on fans, my Noctua NF-F12 will spin at 16%, minimum.

Fans like Silverstone's AP(123 version is my favorite) fans and Noctua fans tend to under volt very well. If he ever need to look for some fans, those would be a good start.

I have my Noctua on my h-55 radiator, the stock h-55 fan as top exhaust, and the 2 stock cm fans as intakes. The only fan that turns below 50% is the Noctua, the 3 stock fans have a low limit of 60%, which would put them around 7v. Fortunately, at that setting, they are very, very quiet, and don't get loudish until they hit 80-85%, @1000-1100 rpm
