Great controller for my AVR fans
I currently use this as a controller that’s connected to my Yamaha AVR to power three 140 mm fans that push air into the top to cool the unit. This pwm controller works great to control the speed of these fans, I run it at 25-30% and it turns on immediately as my AVR does as I have it powered from the jack in the back of the AVR.easy to use, noise level depends on what fans you have.pros: good build quality, decent control (the dial isn’t my favorite but it’s pretty set and forget), reliable.cons: none really

This is a great controller to control the speed for various fans.
This is a great controller to control the speed for various fans. I use it as part of my mini BTC mining farm setup and it works great. If you need to controi the fan speed of various PC case fans this is a winner.

Good enough for my needs. And budget friendly.
Not perfect, but this will suit my simple ventilation needs for my soldering, and painting projects. This works well for these small applications. Iâd buy again.
Amazon Customer –
still working well after several months of use
I own a few of these now (all by this company / purchased from this specific listing) that I have been using for 3+ months now. They run several fans for at least 8 to 12 hours a day (around 5~ daisy chained together) at low speeds with no issues. I set the control so it’s around 10 o’clock give or take and the fans are silent.

Great for my indoor glass greenhouse
Works great! I use it in my greenhouse. The setting options are perfect. Easy to install. Good size for my enclosure.

Died randomly.
Worked great then randomly died after 2 months. I was only running 4 .42 amp fans so it wasn’t an issue of being over loaded.
