ok thank you.
. are you going to test now?
I'm in the middle of testing. I've finished the series with the P14 on LNA and the P14 on ULNA. Those produce very quiet running, at around 20 dBA.
I did a quick exploration of the TY-140, and then on to the current series - the 800 rpm Slip Stream 140. With this I can get ultra-quiet running, in the mid- to high teens.
when I'm done with that, I'll put the P14 back in to test. But each series takes a long time: each fan runs 45 minutes, and I do processing for another 15 minutes, so it's an hour a fan. Each series involves about 15-20 fan runs. And I have to take time off for real life.
As it stands, the Slip Stream 140 run is a do-over: I was not satisfied with my method the first time.
