Opinions on PWM fan controllers

[bad.samaritan]

I bought the SPAL twin 11" fan setup and their controller, a few years ago and the controller has died according to tech support and there is no replacement option from them.

So I'm looking for a PWM fan controller, preferably with the thread in style sensor. I like DCcontrols but it seems he only does probe style sensors.

Anyone have any experience with the flex-a-lite or painless controllers?


Can the Entropy PWM fan controller be used as a stand alone setup?

Thanks,

Mason
