If that board is anything like mine, you need to go into the BIOS and activate the fan control within.
You can usually specify a threshold of % power to apply to your fans with certain temps.
If you do not activate the tempertature/rpm control, then they will usually only provide maximum power.

If it helps you, see page 2-25 in your Assus M4A87TD motherboard manual.
That will help explain it to you a little better.

yeah most PWM controllers need to be activated in the BIOS or they will just run at full speed, I have my CPU cooler (Xigmatek HDT-S963) set to run at about 60% fan speed then when the CPU hits 50oC to then up the fan to 100% but it hardly ever its 50oC any ways.
