48v fan powering - safest method

Hi there, I'm looking to power 6x 48v fans from my VE system - is this safe to do as long as I fuse it down correctly? (Just coming off the busbar system) - https://www.pchub.com/delta-electronics-thd0948he-a-server-square-fan-a04-48v150a-sq92x92x38mm-4w-p170516

No, use a orion dc dc converter!

Busbar can be much higher than 48v!

I see the Orion would stabilise the voltage however these fans have input range of 36 to 76vdc so it should be able to deal with the changes in voltages; in which case I believe will be ok to be powered from the busbar unless there is any other reason not too?
