How is the cooler hooked up? At anything over @70°C those fans should be at max speed and quite self evident. If corsair link is installed, this can also be the culprit.
The pump should be Sata powered from the psu. A secondary usb is for basically info to-from the mobo via usb. The fans should be attached to the pump and a connector from the pump to the cpu_fan header. If not using corsair link, don't worry about the usb connection, the fans will be run through bios via the header. In bios, cpu_fan should be enabled for performance settings with a duty cycle of 100% at @70°C to start..
Idle temps will vary depending on ambient temps, but low to mid 30's is normal in an air conditioned setting. This is also dependent on case airflow. For best airflow using a large radiator, fans should be set for exhaust, either push or pull, with other case fans as intake for a top/rear mounted cooler, reversed for a front mount cooler.
