He actually says that he was unable to get it in time as it was on
back-order, so he could not show it mounted, so he showed everything
else. The cooling fan is to make enough air circulate to keep the PSU
cool enough, considering that the rubidium gets hot, but the cooling fan
is not the primary cooling method for the rubidium. He do understand the
cooling needs of the rubidium, but I would let there be an active
control-loop for the fan cooling the rubidium.
