before you go changing psus, have you checked the headers with a multimeter to see if you have 12v to them, if not you have poss 24 pin plug fault, motherboard issue, as said earlier molex connectors supply full 12 v from the psu, seems to me may not be a psu issue , connect the molex to run the pump so as no dmage to cpu or board, then check the headers for power with a multimeter, if no power to the cpu fan header or other fan headers , id suggest 24pin issue (poss 12v issue from psu), motherboard issue, as they should receive 12v to the fans headers straight up when the board is turned on
also check the 2 x 8 pin connectors to the motherboard, also the pins and pins condition in the plug itself, they supply the board with 12v power as well
2 x system fan/water cooling pump headers...from the pdf
`` Smart Fan 5 Settings
Allows you to select a target to monitor and to make further adjustment. (Default: CPU FAN)
&& Fan Speed Control
Allows you to determine whether to enable the fan speed control function and adjust the fan speed.
Normal Allows the fan to run at different speeds according to the temperature. You can adjust
the fan speed with System Information Viewer based on your system requirements.
Silent Allows the fan to run at slow speeds.
Manual Allows you to control the fan speed in the curve graph.
Full Speed Allows the fan to run at full speeds.
&& Fan Control Use Temperature Input
Allows you to select the reference temperature for fan speed control.
&& Temperature Interval
Allows you to select the temperature interval for fan speed change.
&& Fan/Pump Control Mode
Auto Lets the BIOS automatically detect the type of fan/pump installed and sets the optimal
control mode. (Default)
Voltage Voltage mode is recommended for a 3-pin fan/pump.
PWM PWM mode is recommended for a 4-pin fan/pump.
&& Fan/Pump Stop
Enables or disables the fan/pump stop function. You can set the temperature limit using the temperature
curve. The fan or pump stops operation when the temperature is lower than the limit. (Default: Disabled)
Displays the current temperature of the selected target area.
&& Fan Speed
Displays current fan/pump speeds.
&& Flow Rate
Displays the flow rate of your water cooling system.
&& Temperature Warning Control
Sets the warning threshold for temperature. When temperature exceeds the threshold, BIOS will emit
warning sound. Options are: Disabled (default), 60oC/140oF, 70oC/158oF, 80oC/176oF, 90oC/194oF.
&& Fan/Pump Fail Warning
Allows the system to emit warning sound if the fan/pump is not connected or fails. Check the fan/pump
condition or fan/pump connection when this occurs. (Default: Disabled)
