DOES USING KNOMI 2 IMPACT YOUR STEALTHBURNER'S PERFORMANCE? We have customized installation print parts for KNOMI 2, facilitating its easy installation into your Voron StealthBurner. In particular, our StealthBurner Main Body not only retains the original fan positions but also incorporates a circular ventilation opening at the top, enhancing compatibility and optimizing heat dissipation.
Page 6 We conducted a comparative analysis measuring wind speed and acoustic energy levels between the original StealthBurner and our customized version featuring vents and KNOMI 2 add-on. The results showed that both versions performed similarly, indicating that adding KNOMI 2 will not compromise the performance of the StealthBurner.
