Do you have a schematic for the Fan controller implemented in TA3020V4?

Im probably going to buy a single TA3020V3C sometime in the future.

Doing softstart and input phase shifter myself, however I havent really found a simple diy fan control so having a schematic would be nice.

The fan controller implemented on TA3020v4 is very simple. has one PNP transistor biased by a small NTC, 50K at 25*C and 2.7K at 100*C. the supply voltage is within 12-14V range, fan 12V DC at 60-120mA. the fan start to spin when the voltage across its terminals is about 4-6V depending on the model. the temperature when starts to spin is about 48-55*C. as the temperature increase, the speed of the fan also increase, providing more airflow. the noise generated is very low due to the low speed. the thermistor must be as close as possible to the output transistors and not to close to the controller transistor to avoid mutual heating and autoderating.

Add to that, what is the TA3020V3C output relay rated at?

R74 must have same value as R20 and R24, the input signal will be applied at pin4, Left In, and pin 6, Right In will not be connected. Output will be taken from pins 1 and 7, without connecting to GND.
if you are using this configuration, no need to bridge the amp using BIPS module. if you want to use-it just to have balanced input, just connect it simply output of BIPS to the input of the amp.

Another question(Yes, I know enough with the questions already, lol). Could you buy a TA3020V3C without the supply caps. Been thinking about buying one and then add a pair of big caps instead, one on each side, mounted outside the PCB.

How much cheaper would it be.

The TA3020v3c has few options regarding the capacitors choice. if none of them is suitable for your needs, then yes, i can deliver the board without the caps, at a lower price. the installation of the new caps will be made on the user's responsibility very careful at the polarity. there are polarity markings on the pcb and caps, so this should not be a problem for anyone.

Smile Volume control ?

Looking at the new TA3020 with integrated BIPS: do I understand correctly that there is volume control associated with BIPS?
Is this feature available with standalone BIPS too ?

Well, you're not so far from the "all in one" module made of BIPS + TA3020 + SMPS
