Water cooled vs air cooled spindle noise level comparison.

This is a question we get at PwnCNC support very regularly. Here is a short video comparison between a 2.2kw water cooled spindle and a 2.2kw water cooled spindle.
The comparison is really unscientific but you can judge by the fact I am speaking normally throughout the video.

Thanks Clinton! You do amazing job of customer service! Thank you!

I just installed my 80mm watercooled PwnCNC spindle. I'm glad I went with watercooled because of the sound level difference. I just saw your video and it confirmed my decision.

Hi Clinton, that's useful info. Thanks for posting!

[@bluustreak6578]

Exactly what I was looking for, thanks!

[@Raynye]

Thank you for demonstrating this for us!

The spindle on the wood resonates louder compared to the other. both should be demonstrated on the same medium. Good presentation, however! keep the great work!

[@wiremonkeyshop]

Thanks for this, but it's not exactly a fair comparison because the air cooled was sitting on a large resonating surface, the spoil board, and free to vibrate. The water cooled was isolated up on the rigid gantry. Regardless, the air cooled is always a little more noisy.

Would be nice to chuck a Makita trim router in there as well to hear the real difference between a spindle and a router which most people start off with I reckon. But in the end, the dust collector will probably win that battle as you just pointed out anyway.

if the question of nice is important ? It can be replaced with the duration of work possibility one .And that is the first principal question to be consider . It is not musical instrument to play some nice music .

Thats a noisy fan on that air cooled. My vevor VFD was virtually silent, just light air noise

[@NeoQJ]

I am kinda regret choosing air cooled spindle for my CNC, too loud for me

[@JoeLazzara]

But is the air cooled spindle really THAT MUCH louder than the water cooled?? Im doing research on them now so I can figure out which one is best compared to my makita router.
I've heard the water cooled is just a LITTLE BIT quieter that the air.
Is the air cooled that bad?
Thanks for any help you could give me. 👍

@@JoeLazzara consider it a quiet router since it has a fan that make it cool and the better the fan the louder it gets, once it's cutting wood it's only a few decibels higher, But it still blows the darned chips all over the place and sometimes overpowers the dust boot on 3d carves leaving a lot of trash and chips on the work piece.

[@JoeLazzara]

@66dvert Thanks for responding!! When I posted my question I was trying to figure out which one to go with and I had decided to go with the water cooled, and I'm really happy that I did!!
Since you have a spindle, you're well aware of how quiet they are lol.
But now that I have that spindle, I can never go back to a router again, I really love that thing.
You're completely right about what you said about the air cooled blowing the chips around, since the fan is at the bottom. I think that's why I opted for the water cooled too, plus it is quieter than the air cooled, it makes carving so much more enjoyable now lol. 😄

@@JoeLazzara thanks, I have 6 cnc's right now in the garage, from 24"x 24" to 127" x 70" for full sheet goods. Every one has a spindle that's water cooled. you are, right once you get that spindle up and running you can't ever go back to a router unless you broke everything and the store is closed for a week.

[@JoeLazzara]

@66dvert 🤣🤣 yes sir, out of total desperation.
