Finding the best fans for your PA120.3

Nice find mate. It's amazing how differently a fan can behave when you stick it on a radiator, compared to in free air.
 
Hmmm...wonder how the noiseblockers would fair, hopefully they'll update this at some point in the future
 
Which specific Noiseblockers? The SX-1's were tested back when we first released the PA Series and were found to be one of the worst performers with insufficient air pressure.
 
Unsure - it was a while ago and they were sent to Australia for the testing and remained there... basically, they weren't included in the testing linked to in the OP because they were already known to perform worse than the fans that were tested when it came to cfm vs noise. (IE: other fans moved more air with less noise).
 
I wonder how much worse they performed, the difference must have been minimal, given the context, low rpm and low airflow (per cfm).
