Other World Computing

92mm Replacement Fan
For use with ThunderBay IV / Qx2 Enclosures

Optimized for maximum airflow
The Shark Fin blade design reduces the turbulance caused by fan rotation, thus decreasing the noise and vibration while increasing the airflow — perfect for quiet system environments.
Long life bearings
The sealed long life bearing system both minimizes friction noise while reducing the inflow of dust for a longer overall fan life cycle.
Optimized for Quiter Performance
This fan provides up to 60% quieter performance in QX2 vs. the cooling solution included prior to August, 2014 and up to 33% quieter operation for ThunderBay IV models vs. standard cooling solution prior to March, 2014. Please note - after these dates all QX2 and ThunderBay models have shipped standard with the new, quieter solution.

Rating: 5/5 Worthy Upgrade June 16, 2014 I bought an earlier version of the Thunderbay that suffered from loud fan noise. This fan is easy to install and reduces the fan noise by at least 90%. Not perfectly quiet, but a huge improvement. Recommended.

I would recommend this item to a friend!
