    Cooling fan for ESC?

    I am wondering if there is a cooling fan I can mount onto my ESC.

    I have seen some heatsink/cooling fan combos that have 2 cooling fans. They are either next to each other or one on top and one angled to the side.

    Does anyone make something like this for the 1/16 vehicles?

    I would stay away from the Integy motor sink/fan. Its' design is lacking intelligence... because of the way they made it, there is ZERO airflow around the motor!!
    Whatever it is I just typed... could be wrong.

    I already have the Integy motor heatsink/fan combo. I thought it was doing a decent job, but if you say it doesn't, what heatsink/fan do you recommen ?

    Also, does someone make a ESC fan?

    I have not found one yet... but I know they are out there!
    If you take the fan off you might notice that there is no way for air to flow around the hole they have for the fan... making the fan circulate dead air.


    I have seen a few home made apparatus's to hold a fan for the ESC, but nothing "factory".

    So what is a better option for a heatsink/fan for my motor?

    Best thing to do is proper gearing! Then throw a fan on there if you need to

    My truck is stock and I am running either a 3s lipo by itself or 2 3s lipos in parallel.

    I would gear down to the included 23 tooth pinion...
    if you already have and still have heat issues, go lower yet... maybe a 20 tooth.

    Fans are not the proper way to solve heat issues... they are only to keep things cooler.

    Thanks for the info. I will install that pinion later today.

    Will the 23t pinion give me more low end or top end speed?

    More low end, less top speed; which is needed to lower temps.

    O ok, I thought the packaging said it was a "high speed" pinion?

    So more low end, which will make it even easier to wheelie?

    High speed as in use it for speed runs with a 3 cell battery kind of misleading!
    You all be able to wheelie better up to a point because it has more low end but will wind out faster

    It depends on your ESC. Some ESC's offer an additional port that will support a fan. In my case I am running a smaller model with the VXL 3m ESC and the Velineon 380 brushless motor. This ESC does not offer an additional port, it only has the cooling fins, but Integy offers a heatsink with a cooling fan for the motor. What I found in this case, is that the fan on the motor offers enough heat dissipation for both the motor and ESC being the ESC is so close to the motor. As far as air flow I found that air pulling away is better. I confirmed this with my local hobby tech. Look at it this way, would you rather blow hot air onto your motor or take it away?

    This is an old thread so not likely to get replies from them. You are making a common mistake in understanding how a fan works when right up against a solid surface. This was debated over about 20-30 years ago by computer builders about fans on CPUs. The experts tested it and found that when the fan blows away from the heatsink only the air near the edges flowed while the pocket covering about 70% of the center of the heatsink didn't move much. This is why all fans blow against flat solid heatsinks. When it comes to vented surfaces like radiators pull/push setups work great since there is flow through the cooler. It is a pretty easy thing to test on yourself just stand behind a fan then stand in front of one. When do you feel the air cooling your skin more?
