that castle fan is not a blower, its a YiMeng 7-bladed axial dc fan rated 3.4 CFM deduct some, for that slick shroud with a sticker on top obstructing the airflow

It could be replaced with a sunon maglev 4.9CFM, 30x6mm fan (cheaper than the whole fan shroud with fan):

its half as noisy and more efficient
12 bucks here:

comparison of the two fans (pressure chart double checked)
i use this on mamba max 3-5S with 35V power cap

Sunon KDE1235PFB2-8, 35x10mm 5-13.8V, 0.8W, 6000RPM, 5.2CFM, 0.06A, 19.5dBA, 5 blades and this for 1900kv motor

Top Motor, DF127015PH 70mm x 15mm, 38,9CFM, 4,1W, 3-Pin CPU fan, 4300RPM, 0,34A1 12V, 37,5dBA, 11 blades
both 12v rated fans
"Designed in Kansas - made in China" Bah, sounds so Hollywood. Hobbywing at least use 50mm fans. A 30x6mm fan on a 2-3000+ watts motor is ridiculous. Overall efficiency is better with fans, good ones and big ones.
Pull a fan from your notebook or PC and see what happens to 'overall efficiency'
