The powered design via SATA and DC 5525 makes installation super easy and versatile. The cooling fan speed knob is smooth and responsive, and the maximum output of 60W/5A ensures reliable performance. Overall, a fantastic purchase that improves my PC’s cooling and noise management—highly recommended!

Simple and highly effective fan controller. I use this to run 6 fans, 4 120mm and 2 60mm 4 pin fans. If you wish, you can run the setup using a 5v adapter but your fans won't spin as fast as they would with a 12v adapter of course. The center pin of the round plug is a 5.5x2.5mm so plan accordingly if you are going to use an ac adapter like I did. The plastic back plate is just a 3d printed cover so you can remove that if you wish to create a different case for the controller. The knob turns smooth and clean with no notchy feel to it. Overall, this is a great value for a variable fan controller for your 3 or 4 pin fans.

This is an excellent PWM fan controller. I use it with an external power supply to power three 360mm fans for an external liquid cooling radiator, which is something like I imagine most people will be doing. It puts out just enough juice and could handle more fans than I'm using with no problem. There are six slots for direct fan connections, if you need more than that then you'll need to use splitters or use a different distributor. The power light is not too obtrusive but then I keep this set behind my PC so it's not easily visible. The dial is very sturdy and has a good feel to it, I imagine it should have a long life of usefulness. It's got SATA powered options as well if you want to set this somewhere inside your case or else get a good long extender. I pulled exactly one star away for one simple reason: it would be nice to have a power switch. The lowest setting on the dial doesn't completely power the fans off, so if you use a wall wart power supply like I do you may want to set something up to switch it off when necessary. The plastic case that the board sits in is 3D printed, and does look the part, but thankfully, most of it is on the underside so you aren't likely to look at it much.

I have an open frame server for ai research and this was a perfect option to control my gpu fans (server gpus don't have their own fans). This is a simple, classic, and cheap 555 timer based pwm generator. That's all you need though. I appreciate having the voice of using a barrel jack or sata power connector for the 12V supply. Speed range is good.

If it's capable of running 6 fans I thought it would run the single fan I need controlled. Not a chance. Speed remains the same and the board gets hot.

Works perfectly! My computer has a fan controller that uses a remote and I can never get the right angle. So I got this and moved all the fan connectors to it. I did keep all the LEDs on the other board due to no connectors but that fine for me. Now no more over heating issues. One knob for all fans keep it stupid simple

Used this for an airbrush spray booth to control the fans. Works super well.

This thing can pull 60 watts. 60 watts of FAN power lol. It’s kind of ridiculous. I’ve had numerous fan controllers overheat and give up trying to move a few server fans for more than an hour or so but not this one. It’s also nice to have two options for power input. Kinda wish it had a type-c power or maybe even control input but for the price this one is already punching above its weight
