I have found TY-140 like all other fans are quieter when spaced 10-20mm from cooler or vent.
NF-A12x25 are very good so no surprise that you are happy with them.
There's no reference to the TY-140 itself, but to the A14, which has a similar blade design
, hence the same conclusion.
My testing of the TY fans reached the same result: there's no motor noise, but propeller noise, which are then amplified by the case. I'm not talking about the sound the A14/A15 (or any other fan like the eLoop) does, when being used as pull fan (radiator, filter, whatever), but actual propeller/blade noise the TY fans make even in free air and low rpm.
I want to keep using the A12x25s ( extra bonus: the radiator/filter has very little effect on the tone of the sound in pull configs due to the blade shape) but being in the era of GPU boost clocks I was thinking of installing the D15 in vertical orientation to keep GPU temps as low as possible (even if sacrificing a few degrees on the CPU) to achieve a higher boost - but this is a future project of mine...the PSU has to go first, then the 7970....
The D15 clearly prefers 140mm fans, but I don't want to buy the TY-147Bs blindly..
