[SOLVED] BIOS And Ai suite 3 Not Recognizing All Of My Fans

[Samsonob12]

Can't control fan speed and the fans sound like a small aircraft.

To diagnose and advise, we need fsix types of info.

1. Maker and exact model number / name of your mobo.
2. Maker and exact model numbers of each of your fans. At the very least, tell us whether the motor power cables from each fan end in a connector with THREE or FOUR holes?
3. Do any of those fans have LIGHTS in them? If yes, then does the fan have a SINGLE power cable, or TWO cables - separate ones each for the motor and the lights?
4. List fans for the CPU cooling system separately from the case ventilation fans.
5. What mobo headers do you have the fans plugged into?
6. IF your CPU cooling system is a liquid-cooled system (not just fans on the heatsink on the CPU), tell us its maker and model.

Since typing this i have found out its the Deepcool Castle 280ex rgb liquid cooler that is ignoring my settings

OK, that narrows it down. Now we still need the info on the maker and exact model number / name of your mobo. With that we can help you select the just-right places to connect the pump and rad fans power cables, and to configure the fan headers used.

As background FYI, the design of that AIO system's MOTORS intends that the PUMP will be powered by a fixed 12 VDC supply so the the pump can run at full speed all the time, and the pump's speed signal will be returned to a mobo header so it can be monitored for failure. The Rad Fans will be connected to a header that will control their speeds to regulate the CPU temperature using the new PWM Mode of control. Depending on the headers available, that header MAY also report one rad fan speed and monitor that for failure. You will note that the system included a 2-output Splitter to connect both rad fans to one mobo header. When you use this, the speed of only ONE of these two can be sent back to the mobo header. This is a limitation of the header design, and really makes little difference. It does NOT affect ability to control the rad fans' speeds. It means only that the mobo cannot monitor BOTH rad fans for possible failure, so from time to time YOU should check that they both still are working.

There is a second cable from the PUMP to feed power and control of the lighted logo on the top of the pump. You can use the small manual control box included with the system for that, or connect it to a 3-pin ARGB lighting header on your mobo IF you have one and let a utility supplied with the mobo to control that light.
