36W 3‑12V Adjustable Power Supply Variable Voltage Adapter with 4‑Pin Fan Splitter Cable, Speed Controller for 2/3/4‑Pin 12V Fans Water Pumps, PC Case NAS Server Router AV Cabinet DIY Cooling

Built a ghetto fan setup at work. Pretty much the best idea I've had in a while. You can attach a couple fans under the desk and a couple on top - boom, perfection. Works great. Handles four fans with lights easy. Doesn't control led separately, it's on or off. I've used it for 6+ months now. It will run for 12+ hours without issue. Haven't really left it running longer. The brick gets a little warm, but not as hot as a laptop charger.

Used this with a CR Box from DIYAIRFILTER.COM and it worked really well. The four connectors connected easily to each of the fans. I love the dial to control speed too. Super handy for all in one electronics for CR Boxes.

I'm using PC case fans to create an intake fan bar to line the bottom of a window. This plug does exactly what I need, which is to have a way to power the PC case fans directly with AC power. The ability to control fan speed with the dial is a bonus. No RGB connector, which is actually a positive feature. I needed the fans to draw air, not draw attention to my window with flashing lights. Using this to power a row of Thermalright fans with snap fit. One connector from this power supply is sufficient to power a row of 9 connected fans. Very inexpensive solution to a DIY hack project that worked out exceptionally well.

This Delinx 36W PC fan power supply with speed controller has been fantastic for my custom PC cooling setup. The 4-port design allows me to connect multiple fans from a single power source which simplifies cable management significantly. The adjustable speed controller is incredibly useful - I can fine-tune fan speeds to balance cooling performance with noise levels. The wide voltage compatibility from 100-240vAC means it works globally without issues. The 3-12V DC output provides flexibility for various fan types. Build quality is excellent with solid connections and quality components. The unit runs cool even when powering all four fans at maximum speed. Installation was straightforward with clear labeling on all connectors. The compact size fits easily in my PC case without obstructing other components. The speed control knob turns smoothly and provides precise adjustment. My PC runs much quieter now that I can dial in optimal fan speeds rather than running everything at full blast. For anyone building a custom PC or upgrading cooling, this is an excellent fan controller. Much better than cheap alternatives.

Works great to power two large noctuna fans. Seems durable so far, does not get hot or anything. Would recommend to others.

Using for a airbrush spray booth. If/ when the fans die they can be easily replaced. The controller is working great for this task.

I added 3 x 120mm RGB and 2x140mm RGB fans to a case with a motherboard with no free fan headers. This was an easy add I already had the fans running on two external RGB Fan Controller Hubs. This allows me to remove the fan load from my OEM HP Onen30L's motherboard and I get to set the fan speeds as I like, which is wide open in my situation. Epic, easy add with no sign of fault that I can detect in 60 plus hours of use since first installed. I'd highly recommend this product, and would be happy to buy another should I need one.

I'm using it with 2 12V DC IP67 Waterproof Fan 120mmx25mm 4.72inch bought separately in a home made desk top airbrush spray booth for use with water based paints. It controls the fans very well but you need to turn the control up to about 3/4 full to start the fans and then you can reduce the fan speed to a lower speed if you desire. With 2 fans it remains reasonably cool to the touch after a couple hours of uses at 1/2 to 3/4 speed (haven't needed full speed with 2 fans in the spray booth.)

Stopped working completely once I added a 4th fan. I never even used this at full power. I guess this piece of junk cant handle more than 8 watts...
