Molex fan connectors4/7/2024 ![]() It's common for a cable to have 3-4 connectors, usually 2-3 sata and a molex connector. ![]() If you have any questions feel free to comment and I will do my best to help you.Your beQuiet power supply has "peripheral" connectors on it, in which you can plug cables that have a bunch of connectors. I don’t regret it, but you know it´s your own decision if you want to do the same. I did this because I did not want 3 controllers on my Mora3. Now we´re ready to go, the speed control can be set in the bios of the motherboard and the power supply is managed directly from the psu. This is a usual setup at pwm pumps for a water cooled setup. I have extracted the 12V and GND only from the original connector so that we still can use the rev counter and the pwm signal of the controller to connect them to the motherboard. I´ve done this because I want to control the speed of the fans, but I didn´t want the motherboard to power all of them. I for myself have added a normal Molex 4 pin connector for an easy plug and run. You have to trim the sleeve a little bit and change the connector for the 12V and GND. In that case the motherboard is used to regulate the fan speed only. I spliced the cable of the power supply in order to prevent damages. I don’t want to damage anything and connecting more than 3 fans to one fan header on the motherboard should be avoided to prevent damage. We want to use more than 3 fans at the controller, that means we have more than 3 fans at the fan header on the motherboard. To show you how it works I will connect three buttons and make a video. In my case I disassembled the pin header because I do not have the right material to plug something in. You can use external buttons to control the light and speed of the fans. Step three: Bring them together at one connector. Step two: Be sure that they can’t touch each other to avoid damages and short-circuits. Likewise, a normal y-Splitter.įirst step: You need 3 headers for the fans. We are going to split all pins to get more connectors. Unfortunately, this also gets rid of the PWM signal from the motherboard but we’ll get that back later with a little trick. Of course you shouldn´t supply that with your motherboards fan header, so we will change the power supply for the controller. I for myself was running 3 fans per channel, that makes me running 9 fans on 1 controller. The only thing I found out for now is the pin for the 5V supply, I can´t figure out which one is the data pin or what signal they are using to control the LEDs ( „Pin 3 – Y“, „Pin 4 – P“, „Pin 5 – 4,5 - 5V“). The last three pins are used for the LED controlling. The only two pins that are similar to other connectors are the first and second pin („GND – Pin 1“ and „12V – Pin 2“). The first thing we can see is that they got five pins. They looking quite similar to other fan connectors, but they are very different. There is still one problem, if you restart your pc you have to set them again. If you’re using the rainbow-mode, you can pause it with the second switch, so you can show any color permanently. You can set the programmed colors or the “rainbow†mode with the first one. The other two switches will be used for the lighting of the fans. ![]() One of the switches will set the fans to performance or silent mode, you can see which mode is activated if you´re looking for the status led. Both circuits can be set with the switches on the other side. The other one for the supply of the fans. One of them is for the 5 Volt supply of the LED controlling unit and the LEDs. We can set the controller’s functions with these switches but this isn’t the only way to do this. On the other side of the circuit board we can see three switches and one status LED. Also, we see two mosfet (purple) for the circuits of the controller. On one side of the circuit board we can see five pin headers, three for the fans (5pin, red), one for the power supply and PWM signal (4pin, green) and one for the optional connection cable (blue). To open the controller, we have to unscrew four PH2 screws in the corners of the controller. So I first opened it to know how it is looking inside. The controller you receive whit the fans has a lot more potential than you would think.īefore we are going to use the controller for something it is not intended for, we should know what is inside of it. Hello, my name is Dirk from PaYFrog Customs and today I want to show you what I figured out while playing with the controller of the Thermaltake Riing RGB fans for my Thermaltake Core P5 mod.
