Overview

The TFC Triebwerk TK-121 120mm x 55mm Low Speed Fan is the low speed version of the Triebwerk Series fans. The Triebwerk fans are optimized for liquid cooled radiators with many features and abilities that normal fans do not possess. The sleeve bearings used in these fans are lifetime-optimized precision bearings for low-vibration, quiet operation, and improved reliability. Built in fan silencers are used to created the quietest possible environment and comes directly from the NB-Multiframe® technology. The silicon inserts are reversible as one side is flush with the fan housing to create a seal with radiators. The other side extends past the housing to create a barrier between fan and chassis or heatsink for maximum noise reduction. The 55mm thickness of the Triebwerks creates a larger blade size and allows much different blade angles to create a staggering CFM to dBA ratio. (61.6CFM,21dBA) Each fan comes with a "piggy back" cable to daisy chain multiple fans together without the use of cable splitters and messy cabling. This allows even quad radiators to be cooled with a single cable connection.
