Hi,
I think i have to revise my succes report from this thread [
forums.reprap.org] about the noctua fan being able to cool adequatly.
I started noticing some random blockages/extruder clicking while printing pla and the tried to feel the airflow behind the heatsink and if I remember correctly the airflow of the stock fan was much higher.
I also pointed my infra red thermometer onto the heatsink and it read 110C, i cant exactly pinpoint where the temp is but under stock condition I was able to touch the heat at all times.
Im not 100% these blockages stem from the new fan but its possible that the 40 to 30mm reducer is taking too much airflow away.
Has someone with noctua upgrade experienced similar issues?
P.S. it might be possible to design a clip that doesnt reduce the air path that much but then it would also not be as focussed as before. Has that ever been done?
