Hyper Fan Temperature Speed Controller - Adjustable Cooling Fan for PC, Laptop, and Electronics - Perfect for Gaming, Overclocking, and Home Office Use

Seems to work well. Moved some of my plants indoors because of the weather and bugs. This will definitely help keep the climate just right.I own 2. I love hyper fan and this controller is a must have IMO. Set temp and fan speed and forget about it. Can control two fans at once, input fan and output fan. Automatically lowers fan speed if temp drops. Love it.The temperature sensor reads 32 degrees Fahrenheit. It doesn't react or change to anything. Simply doesn't work.No information on how to contact the company in any way. No phone. No email. No nothing.I did not know this controller only works on Hyper fans. I had to return it.I love my hyperfan. Very efficient, nice and quiet, great build quality.This temp control is a must have. Keeps my tent in temp no matter what the internal heat load or ambient temperature is.
