Taidacent 2510-4P 3P Manual 4 Wires 0-5V 12V Fan Speed Controller PWM Speed Control On Off Switch for PC CPU Case Fan with Knob (White Connector with Plastic Black Knob)

worked as it should, I was able to slow down fan speed for case as it was running wide open.

Fast shipping. Works great. Just what I needed

I bought a pair of these Taidacent 2510-4P fan speed controllers to build my own cooling system for an older ISO Rack that houses my studio PCs. The old system was clunky, noisy and ran 24-7. So I bought two of these to control a pair Noctua 120mm fans in conjunction with a thermostat controller. This allowed me to set the fan speed on each fan to control the airflow and moreover the noise. These worked perfectly and now the enclosure is quieter, cooler and only runs when the temperature exceeds the threshold set on the thermostat. These fan speed controllers are high quality, well packaged and very straight forward to install. Thank you for this excellent product that made my custom build possible!

They work. I like the fine adjustment for low RPM. I use a few server fans in my pc that are very loud especially on start up as fans hit 100% before bios initializes. These allow me to turn off or set low fan speed on startup. They do seem to be decent quality. only issue I have is I bought 2 and only one came with a knob. i know they are cheap but either do not advertise specifics if you can not follow through or do not have them in description. I seen another review saying they are missing a knob as well so this tells me it is intentional. Have to cut corners somewhere huh?

its working as it should, i have 2x fans on a 4wire splitter and it doing a good job now i can control the speed to reduce noisy fans

Used an old r510 case for a project. Needed to control the fans. Ended up wiring them all to this module and I am able to control the fans easily. Highly recommend

Item works, but the first one i received was missing the knob. I assumed it was a mistake, so I ordered a replacement, but this one also did not come with a knob. Beware this item will be missing parts that are specifically called out in the description.

No frills module to control PWM fan. Two ways to adjust with 2 separate pots to fine tune fan speed that is required.
