    Maxx fan replacement

    So... Brand new Maxx. After a few hours, one of the fan broke 2 of the wings were missing. After reading about the problem, both broken wings on the fans and overheating problems i decided to get a better fan as the sound of the original was also driving my crazy. Just listen to the difference



    After replacing the fan on the ESC i ordered one for the motor too.

    I think the original fan is around 3 cfm, the noctua is 9,4 cfm

    The one i used: Noctua NF-A4x20 5V Fits exactly on top of the heatsink with 4mm screws. All you need to do is the replace the connector.

    seen that one. Itīs a 30mm fan (original 35mm). Less cfm and/or more noise.

    The noctua beige/brown is not exactly great looking but they are super silent and effective

    Thanks for the heads up that fan fits mate. Keep us posted on the result of installing one in the motor shroud as well!

    Nice find, let us know how it holds up. My aluminum fan seems to be holding up to big air so far.

    Will do The fans should have arrived today, but the carrier delivered it to the wrong place

    And btw, i don't question if the aluminum fan works. Seems like quality. For me, it is cfm and definitely also the noise. I see the aluminum fan running at 28k rpm. After all, itīs RC cars not RC planes

    Got the other fan today and this is how it looks:

    Again: 4mm screws (iīll get new ones in stainless steel later) and it sits perfectly stable. I can lift the car in the fan. The Maxx is very quite now but still they move alot of air.

    So if others are also annoyed at both the quality of the fans and the sound level, then this might be a solution
