Yep, both fans are working. The hotend fan in particular seems pretty good to me. The heatbreak fan I'm less sure since I don't feel much air coming out the sides of the SB. Went ahead and ordered a 7500 RPM fan to try. I haven't yet reached out to the supplier as I wanted to check more prints made with the other filament (they've printed fine). I'll reach out to them tomorrow as well as swap back to G2 to see if I have any issues with the current PLA I'm using that seems to be working well with CW2.That's rather weird ... is your hotend cooling fan working properly? Whether it's not heat creep which softens filament in the heatbreak already.
The other PLA I'm using I haven't used a ton on the Voron so I think I may have gotten unlucky that I happened to swap to G2 at about the same time I started using the new PLA.
