The nosram 40mm v2 aluminum high speed motor fan is made of high quality black anodized aluminum and decorated with various engravings

The first production run of our predecessor ( 901837) sold out incredibly quickly

However, development never stands still, and with input from our team riders around the world, we took the opportunity to take this already remarkable fan to a new level

We've made several significant improvements, including upgraded electronics and a redesigned fan blade to provide even more powerful cooling

In addition, we moved the cable outlet to the opposite side to better protect the cable when used in touring cars

Furthermore, we have extended the cable length by 20mm, which allows direct connection to the receiver

The operating voltage range has been increased from 4. 8 - 7. 2v to 3. 7 - 8. 4v at the receiver (note, no direct connection to 2s drive battery)

Our commitment to continuous development!

The high performance aluminum fans are the heart of the nosram fan series

Developed in europe, with a unique fan blade design, combined with specially wound motors for extremely high speeds, they offer maximum thrust and a stylish, classy nosram look

Screws and black extension cable are included

The matching conveyor duct ( 901990) with integrated venturi duct directs airflow directly to the motor to further improve cooling
