Great little fan! I installed these on my son's LaTrax Tetons to keep the motors cool. Needed some modifications to make fit right. Had to cut off 5-6 fins and tighten up the diameter of the heatsinks but they fit like gloves now. They do seem to be keeping temperatures down. A little loud but nothing terrible.

Big into RC cars, did a gear switch out. My motor started reaching about 125° after a hard 30 minute run. After adding this 30 mm heat sink and fan. Removing the 25 mm fan that came on the car put that on the side. Now after a hard run the motor reads 97°. Motor works as it is supposed to highly recommend it to cool your motors on your RC cars/whatever your flying driving or floating

The heat sink itself is well-made and feels durable. It securely attaches to the motor, providing good contact for heat transfer. The addition of the cooling fan is a significant advantage, as it helps to enhance the cooling process by actively circulating air around the motor. In terms of cooling effectiveness, I have noticed a noticeable improvement in motor temperatures during extended use. The heat sink and fan combination effectively keeps the motor temperature within acceptable limits, preventing overheating and potential damage. This is especially important during demanding RC activities or warm weather conditions. However, there are a couple of considerations to keep in mind. Firstly, the design of the heat sink may interfere with other components in your RC car. Depending on the layout and space availability, you may need to make adjustments or find alternative mounting options to ensure proper fitment. It's essential to double-check compatibility with your specific model before purchasing. Another factor to consider is the noise produced by the cooling fan. While not excessively loud, the fan does generate a noticeable humming sound when in operation. For some users, this may not be an issue, but for those who prefer a quieter RC experience, it's something to keep in mind. Installation of the heat sink and fan was relatively straightforward, and the necessary mounting hardware was included. The fan is powered by a 5V power source, and connecting it was a simple process. In summary, the Hobby Fans RC Motor Heat Sink with 5V Cooling Fan provides an effective cooling solution for RC motor heat management. It effectively dissipates heat and helps maintain optimal motor temperatures. However, consider the design compatibility with your RC car and the noise generated by the cooling fan. If these aspects align with your requirements, this cooling solution is a worthwhile investment to protect your motor and enhance performance.

My first gripe with this cooler is that it isn't designed to fit in any real RC car, just around the motor. It has fins on the bottom that don't fit under the motor, which I had to spend half an hour grinding off before even putting it in my car. Then, after putting it in, one of the motor wires fell off (I barely applied any force to them) which I found to be caused by that wire barely being soldered to the motor at all. Overall poor quality and design, you get what you pay for.

Very strong fan for the size good power good airflow keeps motor cold perfect for my mini erevo vxl 1/16 noise level really good looks good

Sure it would have been good with the correct plug. I didn't pay attention

Six months of use review. Good quality. durable fan and heat sync. The fan isn't loud at all. i modified the body of my RC so the fan could stick up through and get fresh air. This was because due to my RC's design in specifically the placement of the battery it made me Mount the fan all the way on the left side of the motor which tucked it behind the ESC and didn't get much flow. 100% an issue with the design of my RC and trust me this isn't the first.

Perfect for 1/16 scale

This is not compatible with a granite Grom it does not fit and the plug is wrong as well.
