No fan in G-Drive?

Am in the market for 8TB of external storage.

Am noticing the G-Raids have a cooling fan while the G-Drives do not.
Isn’t the fan a safety/longevity feature I should want, or do G-Drives operate in a way
not to require them.

Thanks group.

The G-Drive does not have a fan because it is a single drive and doesn’t need extra cooling.
