The verdict
This is the Tier B unit I'd buy if noise matters. HWBusters measured average noise around 10.5 dBA, and Club386 found the fan doesn't spin up until about 50% load.
Both reviews rate its performance highly, and HWBusters notes a Cybenetics Platinum efficiency rating even though it's sold as Gold.
The one shared complaint is no fan failure protection. HWBusters also found loose regulation on the 3.3V rail.
