92mm Replacement Fan

For use with ThunderBay 4 / ThunderBay 6 / Mercury Elite Pro Quad Enclosures
Our quietest fan yet
MagLev and micro-motor technology help to reduce noise while still maximizing cooling efficiency — perfect for quiet system environments.
Long life bearings
The sealed long life bearing system both minimizes friction noise while reducing the inflow of dust. It also helps resist temperature changes, allowing the fan to remain stable and maintain an overall longer fan life cycle.

Rating: 5/5 Quiet and smooth April 26, 2021 Replaced the fan that came with my Thunderbay II which, after 5 plus years of use, was vibrating and noisy. It's great to have peace and quiet again.

I would recommend this item to a friend!
