Possible to reduce fan noise on a Strada EP?

Recommended Posts

Hi all,

The Strada has a two stage powering on process whereby the user:

  1. turns a switch (which illuminates the display which then reads "OFF")
  2. then presses and holds a button briefly to actually start the machine

My issue is that a very loud fan is enabled following completion of step one when the machine is to all intents and purposes still off. I believe the fan is to cool the logic board but I'm wondering can it be safely disabled / swapped for a quieter fan / run at a lower speed.

I expect I will have to get in touch with a LM tech to have a look but thought it best to try and understand the art of the possible first.

Alll suggestions welcome!

Thanks in advance

My suggestion would be to wait until it's no longer in warranty.

I do this as a hobby, I'm not in business and receive no payment for my work a full disclosure is, and always has been, on my review and YouTube sites. Oh, I agree with @dfk41 quite often...well sometimes.

I suppose it depends where the board is...presumably they had a reason for putting a fan there and what it might specifically be that they are cooling.

Logic board cooling?

Perhaps swap it out for a quiet CPU fan of similar rating (no idea if this is a viable alternative, its just a thought)

Edit: Hmm.

 

It is a big fan: https://www.voltagerestaurantsupply.com/collections/la-marzocco-espresso-machine-parts/products/la-marzocco-sunon-ventilator-fan-80x80x38mm-fb70-fb80-gb5-linea-l600

That's probably the bottom line alright... if it has to be cooled to that extent options will be limited. That said it's strange that the fan is enabled even when the boilers aren't.

I know from building computers that the same level of cooling can be delivered in different (and quieter!) ways so worth investigating further.

Thanks - was thinking there might be something that could be taken from the world of computing alright
