Review: No complaints. - It's been working without a hitch for about a year now. No complaints. I bought it because I upgraded CPU, which called for a new motherboard, and I cheaped out on the motherboard, which didn't have enought fan headers to support all my fans, so this device allowed me to manually set a constant speed for my intake fans because I want a positive air pression inside my PC to help push out any dust that might want to settle inside.
Review: Great product - Love this little thing. Put into a raspberry pi mini case I custom built and it really kicked in the fans to overdrive.

### ⭐⭐⭐⭐⭐ Great product

Love this little thing. Put into a raspberry pi mini case I custom built and it really kicked in the fans to overdrive.

### ⭐⭐⭐⭐⭐ It's a fan controller
*by P***N on July 16, 2025*

I was doing a build in an old prebuilt and needed to replace some fans, unfortunately the OEM motherboard had proprietary fan headers so I couldn't just swap in a generic fan. So I bought this controller since there was a spare PCIe slot that I could use. I liked it's footprint and the knobs at the back that allow you to adjust each individual fan. I can't say much for the quality of the design itself and how much power it can output, or how it functions with multiple fans connected as I just slapped in some random beater fan that I had laying around and called it a day, but it definitely suited my needs Unfortunately I didn't really take any pictures of the controller itself, but I will supply a picture of the finished build with the controller inside. As you can tell it's fairly small as you can barely see it underneath the fairly small graphics card.
