Overview
Take serious heat off your high-power Arrma motor with the Hot Racing Twister 12,000 RPM Motor Cooling Fan with Heat Sink. Featuring a massive 40 x 40 x 28mm 7-blade ball-bearing fan paired with a black-anodized aluminum heat sink, this clip-on cooling system delivers race-grade forced-air cooling for the most demanding 1/8 and 1/7 Arrma applications, including the Felony, Infraction, Limitless, Mojave, Kraton BLX, Notorious BLX, Outcast BLX, Senton BLX, Talion BLX, and Typhon BLX.
For drivers running maximum-power brushless setups where motor heat is the primary limit on performance, this Twister system is the cooling upgrade that lets you push harder for longer.
Key Features
- 40 x 40 x 28mm 7-blade ball-bearing fan

- EC5 connector with 12 AWG and 24 AWG silicone wire
- 11.1V (12V max) input voltage
Performance Benefits
- Aggressive forced airflow for maximum cooling
- Lower motor operating temperatures during long runs
- Extended motor service life
- More consistent power delivery in sustained high-output applications
Usage Notes
Important: If you are using a single 6-cell pack, do NOT use this system — minimum input voltage is 11.1V. Loosen fan screws during installation, then re-tighten after fitting to minimize tweaking and binding. Use medium thread-locker (blue) on fan mount screws. For off-road use, ensure fan blades are protected. Uses an EC5 connector — adapter or connector swap may be required for non-EC5 systems. Replacement fan part: Hot Racing RAON404FP.
