carzian , 2 days ago https://acinfinity.com/closet-room-fan-systems/ They have a lot of products, including other fans and thermostats. I've had their media cabinet fans running 24/7 for 4-5 years now with no problems. Highly recommend it. Otherwise you could use something like this and a standard 12v power adapter https://www.tindie.com/products/mmm999/dc-12v-four-wire-thermostat-pwm-pc-cpu-fan/
