Just bought the E3D V6 through E3D-Online (the knockoffs aren't worth the time I spent on them). The "always on" fan is pretty noisy, so I bought a replacement that is ultra quiet, same dimensions. However, the airflow seems to be about one-third that of the original E3D fan. (I don't have any means to measure either of them). Would I be putting my printing in jeopardy if I used this much quieter but much less efficient fan?
