This is also covered in section 2.3.3. "hot and cold inlets and right to left outlet order" in the manual which is included with Pd under the Help menu. Id' suggest reading through the manual as it covers most of the concepts you need to get a hang of patching.

But what do you mean with "fan-outs"?
A fan-out in Pd usually means that a single outlet is connected to two
or more inlets. IOhannes strongly advises you to get rid of them,
because the order the many inlets receive the message from the outlet
is not defined. This is the single-most frequent source of bugs in Pd
patches.
