Hey guys,

i am a little new to the forum so go easy on me!

i am currently trying to improve cooling on my prints however the 30mm fans i have are noisy and rubbish with airflow,

i use a custom built machine with a geniune UM2 board in and E3d v6 hotend.

anyhow,

i want to up the size of the fans to a 40mm fan, however i have no idea what to look for! can anyone possibly point me in the right direction to somewhere in/near UK that can help!

thank you

    My vote goes to the @neotko fan shroud  from YM.

    Works very well with 40mm EBM-PAPST  fans, which are widely available.

     

    Thanks!

    The only problem with my 40x40 using EBM-PAPST fancap is that on UM2 it will hit the sidepanels. But IMO they are the best for UMO/UMO+ frame.

    For UM2 I would use the Gudo fancap that uses thin 30mm blower fans 12v in Serial

    https://www.youmagine.com/designs/um2-centrifugal-fans-duct

    It uses BFB03512HHA-AF00 fans, they move less air than the EBM-PAPST but they move more than the um2 fans (that's easy to achieve since um2 fans are quite weak IMO). The main advantage also is that they are blowers, so they can focus air quite fast, but they move less air, so they are good for small stuff, but not as good as the EBM-PAPST for big prints where the head travel fast from A to B and the blowers won't keep a just as good airflow around the printed part. Ofc if you print at 30mm/s it doesn't matter if you use one or the other fan.

    With my fancap I can do 80 degrees overhangs at 70mm/s 0.2 layer, I wanted something that was able to cool big amounts of plastic in very little time.

    excellent stuff thankyou for the help guys,

    i have some spare 30mm fans i will use up first before upgrading to the EBM-PAPST fans as i think they will be more than suitable replacements, im presuming these are PWM controlled so will literally wire straight into the original fan outputs?

    EBM-PAPST needs around 20-30% to start spinning and is totally PWM-able the other 30mm is also PWMable (is the same model that UM3 uses but um3 uses the 5v model).
