24V PWM Fans
-
Does anyone have a line on some decent 24V PWM controlled fans that ship to Canada? I'm having a hard time finding ones that work with PWM and are 24V.
I'm looking for a 50mm axial fan and 2x 4010 blowers. My stock Tevo fans died, and seem to be difficult to replace directly without spending $80.

@moowcowsia in my experience, axial fans usually work with PWM, and blower fans usually do not.
One type of blower fan that does seem to work with PWM is these small Winsinn blowers: https://www.amazon.co.uk/WINSINN-Turbine-40x10mm-Brushless-Bearing/dp/B07RNPJ1YS/ref=sr_1_3. I think these are the ones used on the E3D tool changer.

If you're willing to use a buck converter to get down to 12v your options open up immensely. Sunon has a lot of good 12v blower options.

+1. There is better fan availability at 12V.
(Assuming that the Tevo output is open drain and not high rail, which is most likely)

@zapta I'm running all Duet hardware. Duet 2 Wifi, and a smart effector. I ditched the stock electronics before I assembled the printer. The printer frame, PSU, and heated bed is about all that was worth keeping from the original kit.
I've got a 50mm axial fan, which seems to work somewhat with PWM and isn't annoyingly loud. It's mostly just the blowers that area a headache.
I've been planning on getting a second smart effector for use with a Volcano nozzle once Spool3d starts carrying the v3, so having to get 6 fans with 24v and PWM is a bit problematic if I can't be sure they'll work. It seems like the buck convertor might be the best option, which is frankly kind of surprising.
A Berd-Air also looks like it might be a good option. It should be fairly easy to switch between smart effectors and they appears to have a 24V PWM model. It sounds like it might be a little on the noisy end without an enclosure though. Anyone have any opinions on those? The shipping isn't cheap on them, but they look like they provide decent adjustability and low effector mass.

Sunon has a 24V fan in their portfolio... But it's a 5015 radial fan.
I've ordered mine via Aliexpress some months ago.

Digikey has them as well.
