Review on 🌡️ KETOTEK KT4000: Digital Temperature Controller Outlet Thermostat - Dual Stage Heating and Cooling, 16A Relay with Sensor - Ideal for Homebrew, Aquariums, Incubators, Pet Breeding, Reptiles by Nicole King

I have this power for 2 fans in a mini wall shelf. I was able to stick a strong magnet to the side of the temperature gauge to facilitate placement on the front rails of my rack for better visibility. It was easy to program and has worked consistently well for the past few months, albeit cryptically as mentioned in other reviews. The PSU itself is a bit larger than I expected, but I had room for it in my case, thankfully without sacrificing airflow.
