Key Features
- Tough Composite Construction — The fan is manufactured from tough composite materials that deliver long-lasting durability and premium performance in all conditions, whether you're driving on dry ground, muddy tracks, or sandy terrain. This material choice ensures the fan won't shatter from impacts and will maintain its structural integrity through countless hours of operation.
- Effective 25mm Motor Cooling — The 25mm fan diameter is specifically engineered to provide optimal airflow across your motor heatsink without creating excessive drag or noise, keeping internal motor temperatures within the ideal range during sustained driving and preventing thermal throttling or motor damage.
- Integrated Fan Cover for Protection — The included fan cover protects your fan from small stones, grass, and debris that can be kicked up during off-road driving, significantly extending the operational life of the fan and preventing premature damage from flying objects during high-speed bashing sessions.
- Direct Heatsink Attachment — The fan is designed to attach directly to your motor heatsink using the included M2.5x16mm cap head screws, creating a secure, vibration-free mounting system that ensures the fan stays in place even during aggressive cornering and jumps.
- Fast and Efficient Installation — Complete mounting hardware is included in the box, making installation straightforward and allowing you to have your motor cooling solution up and running in minutes rather than hours, meaning less downtime and more driving time.
Technical Performance
This 25mm Motor Fan Set is engineered with precision to work seamlessly with ARRMA's GROM platform vehicles. The composite construction provides an excellent balance between strength and weight, ensuring that the fan adds minimal rotational mass whilst delivering robust cooling performance. The fan mechanism is optimised to work with brushed motor heatsinks, drawing air efficiently across cooling fins to dissipate heat generated during high-torque acceleration and sustained driving. The material composition ensures resistance to the vibrations and impacts typical of 1/16 scale RC monster truck driving, including bashing, jumps, and hard landings. The mounting system uses M2.5x16mm cap head screws, which are standard fixings compatible with GROM-series chassis and heatsink designs. Installation is designed to be tool-efficient and accessible, requiring only basic hex key tools typically found in any RC enthusiast's toolkit. The fan cover acts as both a protective shield and a guide for airflow optimisation, helping to channel cooling air directly across the motor whilst keeping debris at bay.

Frequently Asked Questions
- Which ARRMA vehicles does this 25mm fan fit? — This fan set is specifically designed for ARRMA's GROM platform, including the GORGON GROM and QUAKE GROM 1/16 scale brushed monster trucks. It will not fit other ARRMA scales or model series, so it's important to verify your vehicle model before ordering. Always check the model number on your vehicle to ensure compatibility.
- Why do I need a motor fan for my RC monster truck? — Brushed motors generate significant heat during operation, especially during sustained acceleration and high-torque driving situations. A dedicated cooling fan helps dissipate this heat away from the motor windings, protecting against thermal damage, extending motor lifespan, and maintaining consistent performance throughout longer driving sessions. Without adequate cooling, you may experience motor burnout or reduced power delivery as the motor thermally throttles.
- Is installation difficult? — No, installation is designed to be straightforward and efficient. The fan attaches directly to your motor heatsink using the four M2.5x16mm cap head screws provided in the box. Most users with basic RC maintenance experience can complete installation in just a few minutes using standard hex key tools. ARRMA's design philosophy emphasises ease of servicing and maintenance.
- What material is the fan made from? — The fan is constructed from tough composite materials engineered to withstand the vibrations, impacts, and environmental stresses of RC monster truck driving. Composite construction offers a good balance of strength, durability, and weight efficiency compared to plastic alternatives, ensuring the fan won't crack easily from impacts and will maintain its shape and performance over extended use.
- Will the fan cover protect against all debris? — The included fan cover provides protection against small stones, grass cuttings, and typical debris encountered during off-road RC driving. However, it's not designed to be 100% waterproof or completely debris-proof — it's an airflow-optimised protective screen. For extreme off-road conditions like water fording, additional protection may be considered.
- Can I use this fan set with other ARRMA models? — No, this 25mm fan is specifically engineered for the GROM platform's motor compartment and heatsink design. Other ARRMA scales and models may use different fan sizes or mounting configurations. Using the wrong fan size could result in poor cooling performance, fitment issues, or even damage to the motor heatsink. Always verify compatibility with your specific vehicle model.
