Replace stock Cooling Fan with Noctua 4010

I would like to reduce the noise of the cooler fan a bit.

Do you have any indication if the 8.2 m^3/h of airflow provided by the Noctua 4010 Flx would be enough to keep the extrder body cool?

Cheers!

I wondered about this as well for the Hemera. I went ahead and tried it anyway. It seems to be working fine. After about 2 hours of printing at 255°C, the heat sink is warm to the touch but not uncomfortable. Have not experienced any noticeable negative effects yet, but would like to hear from the pro's on if they think it's a bad idea or not. Using NF-A4x10 FLX without the "low-noise adapter"

Hi Hans,

Our recommendation is to use a fan with a CFM rating of 4-5 CFM, if the fan you are wanting to use is capable of that CFM then you shoudln’t have any issues.

According to the specs the 8.2m^3/h should work out to 4.8 CFM, so it should work just fine.

I’ll give it a try.

Hi,

So I've tried the Noctua NF-A4x10 with about 4,8 CFM. That gave me a jam about quarter to half of the way through a two hour print. I'm guessing that either the airflow is insufficient or the pressure is. Could someone provide me with the specs of the stock fan? Thanks

According to this its only 6.8 CFM: https://www.thermalfx.com/fans/40/XYJ12B...

However I got to say it feels significantly more powerfull than the noctua.
