14:50 this is because the Tornado fans were created to generate high static pressure instead of high CFM. If you could do some testing through a few radiators (low and high density fins) and add static pressure to your testing, I think you would have a more comprehensive idea of what each fan is doing as far as moving air. I liked ur vid tho gj
I have a rad now but it arrived after these fans were tested. From testing so far. air speed thru the Rad and my U12A cooler are equivalent. Now max static pressure testing isnt really what I am going for. like making a windtunnel or building an air pump / pulling air thru a tube. I have a V3 of my testing method in mind and it includes a lot more types of tests as well as adding Temps to the cooler testing. I'm just not there. to small and no budget from youtube / not enough viewer support memberships. :( I hope to get there one day. I would like to add more tests. I started all this because I was unhappy with all the larger channels testing methods. Anyways: Thank you for watching. I'm glad you liked it.
at the beginning, the name of the fan brought back memories of my Gentle Typhoon i got probably in the early aughties that i still move forward between my quieter builds. was happy to see it later on in the video! 🥳
so there is a perceived loudness value called Sone. dB=33.2*log10(Sone)+28 so converting it to calculate for Sone. lets say 15dB = .41 Sone, 20dB = .57 Sone, 25dB = .81 Sone. I am not a sound eng, I'm mechanical so this would be a great question for that specialist.

I have one of these in my pc case as exhaust :)
liking it?

the typhoon is still a great fan. agreed.
thank you for watching :)
Would 5db be roughly 41% more noise rather than 50% more since 2^(1/2) = 1.414?

Good stuff, thanks Bill.
