Overview
Keep your Traxxas Mini Maxx ESC running cool, consistent, and reliable with the Hot Racing BL-2S ESC Aluminum Heat Sink with High-Velocity Cooling Fan. This bolt-on cooling upgrade pairs a precision CNC-machined aluminum heat sink with an active high-velocity electric fan to dramatically improve heat dissipation under hard driving, extended runs, and high-load conditions.
Heat is the silent killer of brushless electronics. As ESC temps climb, throttle response gets sluggish, performance fades, and the system can even shut down for protection. This active cooling solution actively pulls heat away from the ESC and spreads it across a high-surface-area aluminum sink — keeping your power delivery sharp and your run sessions long.
Key Features
- CNC-machined aluminum heat sink with integrated cooling fan
- High-velocity electric fan for forced-air cooling
- Secure clamp-on mounting design — no modifications required
- Direct fit for Traxxas BL-2S ESC
- Replacement fan available as Hot Racing MH3030M
Performance Benefits
- Forced-air cooling dramatically improves heat dissipation
- Helps prevent thermal shutdown and power fade
- Maintains consistent ESC performance during long runs
- Aluminum sink spreads heat evenly for faster cool-down
- Ideal for high-load, aggressive, or extended driving sessions
Usage Notes
RC Scale: Designed for the 1/10 Traxxas Mini Maxx platform. Ensure the ESC heat sink surface is clean before installation. Verify fan clearance and airflow direction (air should pull heat away from the ESC). Secure all wiring away from rotating fan blades. Monitor ESC temperatures during initial use to verify proper cooling performance.
