Someone that hat pays attention nice.

I designed a fan shroud 6 months ago and found higher temps if the Scroud was mounted to close to the motor. In fact I found higher temps if the fan was mounted to close to the motor without the fan scroud as well.

Even the motors with well ventilated cans need a little space between the shroud and the motor so you get the benefit of cooling from inside and outside.

I've seen some people mount the duct up against the motor. If there are no holes in the motor, then you deadhead the fan and it will flow zero air. I mounted a duct and found my motor came off hotter than without a duct.

you need to mount them about 10mm away from the motor too close to the motor the magnet strength from the rotor will slow the fan down

Lat Weekend one of the fastest stock racer at TQRCRacing bought the Direct Flow Fan Shroud and installed per my information.
His R1 V21 17.5 came off with 182F before installing the Fan Shroud and the Temperature dropped to 156F after installing it.

The main issue is that the most people measure the motor temperature at the wrong position on the motor.
You have to measure the Temps directly in the motor at the coils or rotor and not on the stack or sensor board.
Or use the Temperature function of your ESC they use the RTD of the Sensor board wich is installed quite close to the Coils and rotor.
