Taidacent 2510-4P 3P Manual 4 Wires 0-5V 12V Fan Speed Controller PWM Speed Control On Off Switch for PC CPU Case Fan with Knob (Solder Connector with Plastic Black Knob)

For me this is perfect, but my tested limitations are it was unable to control the one Noctua but otherwise only 3-pin fan I have and tested, and my 4 pin PWM Watahai blower fan on this board's lowest dial setting sounds more like 30% rather than 10%. I've heard it go lower when plugged into a computer. My 80mm Arctic fan and others seemed to scale linearly to the dial setting though. Besides that, this is what i was looking for; a PWM computer fan controller that runs off of any 12v DC source and not USB. I wanted this to repurpose an old Xbox one fan to cool an inverter case for a battery bank, so I had to hack up fan cables and find pinouts then solder to get plug and play perfection but this works great with almost all of my numerous 4 pin PC PWM fan I have. If you want adjustable or set it and forget it 12v fan control for your projects, this is fantastic. I don't think it supports 3 pin fans though it could just be my particular 65mm Noctua fan. For how simple it is I don't think $10 is a rip off but it also seems like it could be at least a little less. Highly recommended nonetheless

I was unable to control speed on a 4 wire blower. On/off only. No speed control. But I found on our fan that the PWM wire was YELLOW and the Tach wire was BLUE. After switching it works very good!

I use this product in combination with an Industrial Noctua 4 pin PWM 12V fan to control the speed of a ducted ventilation system.The first feature of value is the red LED that indicates when power is being sent to the fan.The second feature of value is the prominent marker on the rotating knob which provides excellent feedback as to what percentage of the range you currently have selected.The third feature of value is by far the most important. It provided uniformly progressive speed control to the point that the fan turned slowly at its lowest speed. This information was determined by first running the fan with a variable voltage lab power supply and varying the voltage to change the speed. I measured in 1 volt increments from 15 volts down to the point the fan stopped turning. This low-speed point was 5 volts and .19 amps. In stark contrast, this PWM device kept the blades spinning smoothly down to .05 amps. After that point, there was a distinctive click and the red LED turned off. I did not have to alter the potentiometer setting to achieve this perfect performance.The fourth feature of value is the wiring configuration. The red and black wires are easily attached to a very wide range of 12 volt power sources, not just computer chassis.I will continue to use this PWM controller in all of my future builds. I can’t think of any improvement that is needed. In addition, the price is very competitive.

Works as designed and fits in my 3d printed control box. Has been controlling a BeQuiet 120mm exhaust fan for weeks straight.Requirements:-Soldering knowledge and equipment-12v Power supply-Enclosure of some kind (optional but nice to have)Knob feels nice.Build quality is top notchGreat value

This was a great solution to a problem I had. My car amplifier kept overheating due to lack of airflow from where it had to be placed in my truck. Used this to power the computer fan I was putting behind the amp. Worked great.

producto falla muy rápido, personalmente no tengo buena experiencia con el producto, casi no lo utilice y de repente no sube la velocidad ni tampoco baja, solo se queda en digamos la mitad de su máxima velocidad y funciona para apagar, no lo recomiendo por eso no tiene nada de duración, es mas como de juguete, disculpa al vendedor pero es mi experiencia personal.

PWM 4 wire controller for brushless 120X38 mm axial 5000 max RPM fan pulling 1.6 amps @12 volts max falls well within operating parameters of the controller rated @3 amps. Seperate SMT on board trim pot sets start RPM. Nice feature. Main potentiometer has a solid click "zero point" off switch for absolute power off function. Main speed control pot is not as linear as desired. Most adjustment is in the first 50 to 60 percent of knob rotation travel. Also, the main trim pot post has a pretty short stem limiting protrusion options to bezels or mounting surfaces thicker than .060 inches between the knob back and mounting surface. Spec. states it's 25khz pwm. Single power input raw wire pair input with a 4 wire PC fan connector. Overall, works great for my application. Tested for a mere 12 hours since receiving it.

Update: used for a couple months; left on for days, zero issues. Controls speed over full range. Used the plastic shipping container as a mount with Velcro. Exhaust system sips very little energy from house battery bank. Has received much more abuse than it would have in a normal PC application.Unusual application. I’m using this with three 4-wire cables in series for a 6’ extension and an old PC fan and new dryer vent duct to hopefully work as air ventilation on a Lithium house battery for remote van life. Little plastic box it came in will be perfect for mounting with 3 holes drilled and cut in. Worked great on initial test. Description says working voltage up to 15V, charging takes it up to 14.4V, so, should be OK if the fan can handle it. Have a second fan for backup just in case. Will update after heavy regular use.
