  • Worked as Expected.
Perfect little plug-and-use gadget! Nice size, Alright durability, Great compatibility, Smooth voltage adjustment.

  • Great for DIY computer fan air purifiers
This one device makes it so easy to use 2 blocks of triple computer fans to build a DIY air purifier with 2 Filtrete MERV 13 air filters (12" x 24"). Just tape the fans between the filters with cardboard to block off the top and bottom, plug this fan speed controller into the fans and a 120 volt outlet and voila! instant very quiet air filter. Works really well. ... show more

  • Simple, effective fan controller
Bought this because I have more PC fans than I know what to do with, and I do not regret it at all. I have an office/gaming room that has 6 monitors, a gaming PC, a server, and 2 3D printers in it. The room gets HOT! I use this to power 2 200mm PC fans that sit in the window, pulling in cool air (or pushing out fumes from the printers, as necessary). It works perfectly. Twist the knob right and the fans go faster. Twist it left and they go slower. All the way left turns them off. This thing is not "smart" at all, but it gives you complete manual control over 2 fans, which is exactly what they advertised. I love it, my cat loves it, my wife loves it. If you have a use for a wall outlet 3/4-pin PC fan controller, this is a good one. ... show more

  • Nice, good speed control.
Seems to work well, plenty of cable tenth. Took off one start as the main power connector is easy to disengage, loose.

  • Works perfectly driving 2 fans
This is powering 2x server cooling fans on 2x mini gaming PCs sitting next to each other. In my tests, it outputs a little more than the advertised 24w. If you're looking at this, you know what you're doing. This works perfectly.

  • Works perfectly, easy to wire, couldn't ask for more.
We have two 12DC computer fans which I custom mounted to the rear of our in-home bug zapper, as my wife's guinea pigs eat so many vegetables and fresh fruit, well, it's just inevitable that fruit flies will find their way into your home. Doesn't seem to be any way of avoiding this, especially when you walk into Trader Joes and see those little buggers buzzing all around the veggies. The computer were a bit too loud so we had to tune them down to about 1/2 speed and this 12 volt DC controller really did the trick. The dial is easy to read, fully adjustable, no issues with current distribution or lack of power, it simply works and works well. The guinea pig cages are now much quieter and the bug zapper is working much better than before this custom addition. I would absolutely recommend this controller. ... show more

  • A good PC fan speed controller
Here's all one needs to know: this unit varies the DC voltage to 12 VDC fans (3-12 VDC) for "speed control" and DOES IT QUITE WELL! It's main use is to make "loud" PC fans "quiet" by slowing the blade rotation. The "Y" connector is quite handy for controlling TWO FANS AT ONCE. Operation: 1) connect the device to the fan's power connector 2) plug the unit to a wall outlet 3) rotate the knob to turn it on ("CLICK!"). A GREEN LED indicates it's powered up. 4) rotate the knob enough to get the fan blades spinning 5) back-off the knob to get the required "quietness" from the fan (you'll find the fan is still moving "quite a bit" of air!) 6) if desired, "tape down" the knob to keep it's setting from being changed 7) Walk Away, leave the fan alone, and let it "do its' thing" If you need to change the fan speed later: undo the "tape down", re-adjust the knob "to taste", then tape down the knob again. I ** DO INDEED ** recommend this unit! ... show more

  • Not UL approved
Unit worked but I threw it away because it is not UL approved. Not worth the possibility of a fire.
