drobo 4d Fan replacement


i have an old drobo 4d / DRO4D-D (2nd gen.) with a very noisy fan.

Now i search for a new Fan before i open it.

Did anybody know which size the 4d Fan have, 80mm/92mm/120mm/140mm?

Hope anyone can help me

hi chamsin, a quick search on the forum found me this large thread which might have helpful info for you :slight_smile:

thanks, i wasn’t sure if it’s the same size in a drobo 4d.

so it’s a 120mm fan, perfect!
