Hi, In this case the fan is the primary cooling method. The heatsink may help a bit, but the fan appears to have done most of the work since the base is not that hot even without the heatsink. For testing the 5680's I got on their PCBs, I just had a tiny fan on standoffs stuck on top of them which cooled the whole thing well.

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.
