Amazing fan. I used to have a TA05 with a Mamba Max 7700 and it used to trigger the thermal shutdown after 10-15 high speed passes. I now run the new 9000 motor with this fan on the Mamba ESC and I can make high speed passes non-stop until the cut-off triggers on my 40C 5300mah lipo pack. This fan pulls a lot of air onto the ESC and really helps keep it cooler. Now I'm going to have to change all my ESC and motor heatsink fans to this. Definitely recommend this to everyone.
