Default Minimum voltage to run 24v fan

Hi everyone,

I've ordered a couple of 80mm adda waterproof fans for my viv. These are 24v.
I'm familiar with the concept of undervolting fans and most of the 12v fans in my pc are currently spinning at 5v

Does anyone with experience know if a 24v fan would spin reliably with a similar drop - i.e would I be able to run them at roughly half speed using a 12v adaptor - or would it be better going for 15/ 18v to be on the safe side? It would be great if they'd run off 12v ok as good quality adaptors are much easier to get hold of at a decent price and I seriously don't need all the airflow these fans would give at full speed.

Thank you!
