Question Part cooling fan for SB

[LasseKongo]

Finally getting to my long overdue replacement of the Afterburner with a Stealthburner on my 2.4.
I have purchased a couple of 5015 fans for part cooling, GDStime 4500 rpm sleeve bearing and 6000 rpm ball bearing variants.
Connected them to a bench PSU for testing, and the difference in noise (and airflow) are noticeable.

What type would be the recommendation ? i of course want to keep the noise level down if possible.
I print with a Dragon SF hotend with CHT nozzles and use 0.4 & 0.6 nozzles, so not super high flow rates. Filaments used are PLA, PETG, ASA and TPU.

I recommend Delta's BFB0524HH fan. Alternately Fabreeko and West3D have high pressure 5015's available and they reportedly work well, but may be a bit more noise than you want.

Ball bearing fans are recommended in the BOM over sleeve bearings for longevity. i have GDSTime in my Trident and they work well. I also have a couple of the Fabreeko Honey Badger 5015s in my V0.2 Dragon Burner and they work well--that's what I'd go for if I were buying blowers again.

Thanks for the replies.
I guess I will start with the 6000 rpm GDStime and see how it performs, after all it is pretty easy to replace if needed.
