That is still within the spec,  usually given as 5 percent tolerance either way...

Putting a resistor in line will vary the output depending on how much
current is being drawn,  which will tend to cause some devices to interact
with others when things change.  Overall I'd think it not a terrific idea.

If you want to deal with your heating problem (and put some more load on
the 12v supply while you're at it),  add some fans to the case.
