![]() So, if that's your fan type, look in BIOS Setup for the header you plug it into and check whether you have the option to set that Mode in the header's configuration. That fan design can have its speed controlled ONLY by a header that uses the older Voltage Control Mode (aka DC Mode) to control its fan PWM Mode cannot do that. MOST fans with these two connectors are of the 3-pin design that is, the motor has 3 wires (Black, Red and Yellow) from the fan to the connectors, and the female fan connector has 3 holes. Whether you can control the speed depends on the match of fan type to header capability. Hello I installed a fan and it works, but the LEDs arent working, it has a 2 pin connector for the PSU and another one that plugs into the motherboard (pretty sure this is molex). If you connect to a mobo fan header instead, you MAY be able to control the fan's speed, and you WILL be able to observe its speed in BIOS Setup or with software tools. Pitch (mm): Current (MAX): Wire Size: Voltage (MAX): Termination Style: 2.00mm. 799 (4.00/count) FREE delivery Fri, Jan 19 on 35 of items shipped by Amazon. Molex's Micro-Latch Connector System provides a reliable connection interface for industry standard 2.00mm wire-to-board applications. If you connect to the PSU Molex source, the fan will run full speed all the time, and you cannot measure the fan's speed. OPSFALCON 2 Pack 4-Pin (Actual 2-Pin) Molex to 3 Pin 12V PC Case Fan Power Adapter Cable, 3-Pin or 4-Pin (PWM Connector) to Molex Computer Case Fan Power Adapter Cable. This allows you to plug in either ONE of those, BUT ONLY ONE! Do NOT connect both to their respective power sources. The other is a male 4-pin Molex (possibly with only 2 pins mounted in it) intended to plug into a female Molex output from the PSU. One is a standard 3-pin or 4-pin female (with holes) fan connector. On the end of their wires are TWO connectors. Without the third wire, you are hooped.There are some fans supplied as you describe. Motherboard fan headers are three wire, power, ground and pwm/sense/rpm wire. It is likely a two wire set-up so no speed control will be possible. Yeah I can't find a link towards the case maker either. Pin 1 (where the arrow is on the connector this is +5V power) is not connected on either side. For this cable, only 2 of the 3 connectors are filled. Oh yeah - the case is EsGaming Zeus P30 Draft P and the fans are generic fans that come with the case. The connector for the cable between the Lighting Node Pro/Commander Pro RGB ports and the RGB Fan Hub uses Molex 50-57-9403 female socket connector on both ends. ![]() If you need any further data or images feel free to ask. Though I'm not really sure how that button is wired into this setup either.Īny tips on handling this mess would be greatly appreciated. ![]() Now I do have two free 'sys_fan' headers on the motherboard so the ideal solution would be to rewire the 3 fans to the two headers.Īny tips how to re-wire this mess into the headers? Two of the fans do end up in one 4-pin connector, but then the 3rd one seems to be connected into molex?Īnd the single shared wire (between fan 1+2 and fan 3) is I assume for the rgb lighting? There is a button on the case that toggles through the fan rgb modes,īut ideally that would later be handled by the mobo as well. The issue comes from the front 3 fans, being connected to the PSU via molex and spinning full throttle at all time, being quite noisy. I got myself a new PC a couple of days ago and need a bit of advice on how best to handle some rewiring.
