Inline fan - Pro machine

The noise difference is remarkable. The more air pulled through the machine the better for heat exchange, but I use 2- 190 CFM fans (extended exhaust run) with zero smell and smoke removal at least as aggressive as the original exhaust fan.
Note that I also have the exhaust fan grill and fan removed so there is minimal obstruction to airflow.

If you have a remaining warranty you don’t want to do any modifications, so just use the filter option to turn off the whine of the onboard fan, and you will be able to hear yourself think and carry on a conversation next to your running laser. :+1:
