That is a "standard" 3-pin fan connector. You can plug it into ANY 3-pin or 4-pin fan port (these are male, with pins sticking up, labelled SYS_FANn) on your mobo. The connectors will fit - they are designed that way - if you just ensure that the tongue on the mobo port lines up with the groove on the side of the fan connector. HOWEVER there is an issue to consider. The posts above say all your SYS_FAN ports are of the 4-pin type. Normally that means that they operate only in PWM Mode. Any 3-pin fan connected to that port type cannot be controlled by the mobo, so it will get power but ONLY run at full speed all the time. If that does not suit you, I suggest three alternatives.
1. Check in BIOS Setup and your mobo manual (their website is down right now, so I can't) for configuration options of the SYS_FAN ports. SOME mobos allow you to set the port operation mode to either PWM Mode or Voltage Control Mode (aka analog mode). IF you have that option choose Voltage Control Mode for the particular SYS_FAN port you are using - that is what your 3-pin fan would need to be under mobo control.
2. Consider replacing that fan with a 4-pin PWM fan that CAN be controlled by your mobo's SYS_FAN port.
3. Use an adapter to connect this fan directly to a power output connector from the PSU (typically a 4-pin Molex, maybe a SATa power output). It will still run always at full speed this way, AND its speed will NOT be displayed by your system, but it avoids using a mobo port IF you want to save one for another fan.
Option 1 is cheapest but requires a feature your mobo may not have built in. Option 2 will always work but costs you some money.
