I would only use them as a last resort.Hey guys, I know it's not exactly case related, but I came across these blower fans, do you think it could help with ventilation in tight spaces?
Blower fans usually are quite noisy, especially when spinning fast. The 4020 fan does not specify but the 4010 says it is 24-26 dBA at max speed of about 5000rpm. For comparison, an Noctua 40x10 fan generates 20 dBA at max 5000 rpm.
But, I think the weakest link is its airflow volume. I expect it to be around 0.07-0.09 m3/min at max rpm. For comparison, an Noctua 40x10 gives about 0.14 m3/min.
Having said all these, I suppose when you really need ventilation at tight spots, these blowers should still be useful.
