two cooling fans would be desirable over the use of only one

memory storage disk unit.
However, when we reach instant claim 20, and its
dependent claims, wherein the cooling fan is recited as being
arranged in a particular manner in order to induce air flow in

from the examiner in this regard.
Concerning independent claim 29, this claim adds the
