Vordas 3 Pieces 3D Printer Fan - 12V 0.18A DC - 50X50X15mm 5015 Blow Radial Cooling Fan with 1m Cable for Cooling Heatsinks

I have one of these blowers fitted to my cheap 'Clone' 3d printer.I can vary the speed from 50% to 100% during the print no problem.(I've not attempted to 'Start' the blower at less than 50% as it's not a genuine PWM controlled motor !)It's not the quietest, nor the smoothest fan motor...But I can't find a Noctua style equivalent anywhere.This works... And now I have two spares... It was very cheap.

the one i received pull 0.08amps on 12V. The static pressure is quite good compared to competitors and airflow is strong.I improved the static pressure by reducing the play between the cover and the fan of 1mm. Static pressure increased of 60% with same consumption and same flow. Contact me if you want the 3D model to 3D print the upgrade

If you buy these for a Anycubic i3 mega check that polarity of the plugs as the ones on these fans have incorrect polarity.This has caused a fault with my trig orilla board that is installed in my printer....Now the fans just stay on constantly. You cannot shut then down with the relevant gcode commands. Not good as obviously I need to replace my main board now...

Fans no differnet to other radials. Plastic, seem quiet for now.Initial thought, they all don't work!As another comment suggests, the polarity is wrong.Reversed cables in plug, all good.

Very poor quality fans. Each one lasted around 15 hours before the bearings wore out and made a horrific grinding noise which also dramatically ruined performance. Strongly NOT recommended.

Great fan. Surprisingly quiet too. Much quieter than my other 5015’s

Nice product but noisy

Surprisingly quiet for a cheap set of fans. Good airflow and has certainly helped with the 3d printing
