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.
acinfinity is probably overkill for me but honestly very tempting.
I did see that thermostat pwm board on amazon. When you say a "standard 12v power adapter" do you mean as in... like a transformer plug with 12v output and the right amperage?
