IF you can figure out what the old system pins do, here is how the current "standard" 4-pin fan connector is wired.
HOWEVER, the fact that the old fan and mobo use a connector DIFFERENT from what has become "standard" means it is also possible that the PINOUT they use does NOT match what is the standard today. Is that right? Of course, that also ensures that you can only connect one way. And that sleeve has some slots in one side that match "tabs" or ridges on the outside of the old fan's connector. Instead it MAY have a sort of "socket" of plastic with the pins inside that sleeve. This leads me to suspect that the header on your old mobo does NOT have that same male fitting with the tongue. Now, you refer to those ridges as "tabs". On the mobo MALE header, there is a plastic "tongue" sticking up beside Pins 1 to 3, and those two ridges fit on the outsides of that tongue. IF it's a 4-pin connector, Pin 4 is outside the range of the ridges. On all current computer fans the female connector on the end of the wires has two ridges running down one side. It is strange it shows one speed but a voltage range.There MIGHT be more to this than you think. All are (6)4 pin headers for the fans except one and it is a 3 pin header. When you buy the fan make sure you can control the speed: If you don't own a fan you can find some fairly cheaply but you need to find out what controller you have. Set to 100%, then 40% to see if the speed changes.ĥ) Example fan profile: case fan at 40% speed until 40degC then RAMP up to 100% speed at 80degC (it will never reach 100%). May have to just try a fan).Ģ) Enable fan control in the BIOS if needed.ģ) Download and install your motherboard fan control software (motherboard support site).Ĥ) Play with the fan profile. Older motherboards may have VOLTAGE only for everything.ġ) Determine what TYPE of controller you have (not always obvious. My motherboard supports both PWM and Voltage for the case fans, but only PWM for the CPU_FAN controller. The two types are:Īdditionally the FAN controller must be capable of controlling this. MOLEX is usually not controllable, though there are some rare exceptions which work with 3-pin/4-pin adapters. *There are two types of fans that have speed control.
