DC Axial Fans
Wakefield Thermal's line of DC axial fans range in size from 30 mm x 10 mm to 120 mm x 38 mm with the most common sizes in between
Wakefield Thermal produces a line of DC axial fans used on fan heat sinks which are commonly used on heatsinks to support BGAs, VGAs, and CPU coolers or as chassis fans. The fans range in size from 30 mm x 10 mm to 120 mm x 38 mm with the most common sizes in between. The fans are available in 12 V as the most common, but other voltages (5 V, 24 V, and 48 V) are possible upon request. The standard configurations include 2 wire, 3 wire (tach), or 4 wire (PWM) and can be customized to support any range of connectors.
