BERSERKER VINDR Ultra-Performance 4010 Axial Fan 24V 4010A-24V-A 40x10mm

Taking inspiration from two thousand years of viking shipbuilding, which when aided by strong vindr were the fastest in the world,  BERSERKER - the brand representing unparalleled quality introduces its newest line of 3D printer components, Vindr (Norse for "Wind") Fans. These fans were diligently sourced and each fan in the lineup have been tested to outperform any readily available fan on the market today (this fan performed 35% better than the performance fan we tested). These are designed to withstand high temperature environments, with an Insulation Class F rating (155C).

*Diode may be required on signal line with these fans*

These fans have a dedicated tachometer / speed controller line. These give you control and visibility over the performance of your fan, use standard hardware controlled PWM and unlike some that only give you an alarm line (tells you the fan is dead) - this allows you to monitor RPM and control what happens when things are not as expected (e.g. if RPM drops significantly you can safely pause your printer, kill power to your hotend and avoid a crazy bout of heat creep). Don't have a signal pin? Just cut the wire and it will operate as a standard PWM-able 2-pin fan.
