Looking for a good closed loop fan controller for my DC load...
As you may have noticed in previous posts, I intend using a water cooler for my DC load - One pump, one fan.
I want a supervisory device that fits the following profile:
Sits on the SPI bus.
Has one or two PWM outputs for fan control.
Has two tacho inputs for fan speed measurement.
Has one or more temperature measurements.
Has closed loop temperature control.
A good example, but over the top for my application, is the Analog Devices ADT7470.

Anyone had any experience with this issue?
Any recommendations?
Much appreciated.
