Dear friends,
I am adding a cooling fan above the controller board with simple aluminum L shaped bracket.
The size of the fan is 80x80x25mm therefore it is capable of cooling every motor drivers and also controller main board.
it is 2 wired, 24V DC fan, consuming 0.15A.
I am planning to connect the wires of the fan to the controller board input ports directly.
Than, when I plug the power cable of K8200 it will work. No problem for this.
Do you think that connecting the fan wires to the controller board input ports will be harmful for the board? (will it affect board input power and its stability?)
And also should I add resistor to the cable of fan for current protection?
If you mean the 15v screw terminal you are good to go.
The fan takes way to less power to interfere with stability of the power input.
But it might have issues to run itself, cause it’s designed for 24v power.
At least it will run a lot slower than it’s desigend RPM.
Why don’t you try this instead :

Uses only a small 40mm fan and keeps all components cool. Also protects the Controller from damage.

Actually I will apply the solution you suggest later.
My solution is just to save the day.
I do also have 60mm fans. They are working with 12V. I can also use it.
My first concern not to damage the electronics.
But if you say that nothing will be harmfull if I connect the wires to the 15V screw, it is good news for me.
Than you think that, no resistor required addinf in series with fan, right?
Nope, not necessary.
The Fan will not draw more power (at least not significantly more) that its design spec for 24v.
A series resistor would only be needed to reduce the current if you use fans with less specified voltage than
you input. I.e. 12V fan at 15V supply.
