Very fast fan, probably one of the best in the market. It's the fastest fan I've ever had on 6-cell nimh. My only wish would be that Yeah Racing would come out with a 3-cell lipo version. I didn't read the specifications and blew it on 3s lipo, but that would have been expected. Also the wires are a good thickness and should be pretty sturdy (compared to some other fans). Great fan for esc
This is A MUST upgrades for anyone who max up their motor power. I own several brushless with high KV ratings, big Amp gulp and overheated above 200 degree, 3 motor killed even after using common heatsink fan.
But after installing Yeah Racing TORNADO fan i couldn't believe what i see, it really blows and cool my motor in just a few seconds the heat gone like magic. Truely a heat killer and save my motor. The motor fan also very beefy and tough! Very good for my off-road application. You can really felt the wind twrilling and blow every channel of heat sink fin around usb the motor. Damn! this thing as cold as my pc usb fan! I love it! I will buy some more soon for my crawler esc and buggy.
