What Is the CFM of the part cooling fan?

I have been searching all over the place and I cannot seem to find the cfm rating of the radial part cooling fan. Does anyone have any idea what it might be? I tried to judge by other simmilar looking fans the same size but they ranged from 4 to 20 so that was a dead end.

I had upgraded my hot end cooling fan on my MK2 to a Noctua fan and now upgrading I now have a spare. I am trying to figure out if the spare Noctua fan I have now has a high enough air flow at ~4.8 cfm to be a reasonable part cooling fan. The part cooling fan on there now is far and away the loudest thing on the printer so I am mostly just looking to quiet it down some so if you know of a quieter replacement blower fan with enough airflow that would also be appreciated.

Thanks.

Re: What Is the CFM of the part cooling fan?

it's not just the CFM, but the radial has significantly more static pressure. radial blower is always better which is why it's used, especially compared to a noctura which already has LESS static pressure than the stock fan.... the 10mm noctura has 1,78 mm H2O static pressure, while a typical 50x15mm blower has like 15-20mm H2O .

Anyway, i think it's 5-7cfm, depends....

That is a good point about the static pressure. I will just keep trying to track down a quieter radial fan.
