That's very helpful and wise insight, same for what you said
@Event Horizon. As mentioned - the Asus Dual (non Evo - that seems important) seems to rate extremely well in terms of cooling/temps for the regular 4070S. Regarding the Ventus though - that's interesting to hear. From my wide sweeping research, many people seem happy with the Ventus (both the 2x and 3x) across both the S and Ti S range for temps/noise (maybe less so for the 2X). I know there was a bios issue, but that has been resolved. So I'm interested to hear you say that, as the only 'cheap' thing I can see is the possibility they don't use ballbearing fans (and I guess the plastic backplate - but that doesn't mean much to me). People do say the 2X performs well enough for cooling in the Ti S range though so if the Dual is better in the 4070S category, then logic suggests it might be marginally better in the Ti S category too. Though ultimately, still
noisier than a 3 fan card, and noise is important.
See here for example for a comparison of 2x and 3x Ventus.
Definitely agree about coil whine but yeah that's luck of the draw I guess. I have an anti-sag prop, so no worries there even if do end up with the Ventus 3X. In terms of non-ballbearing fans, is it the lifespan that's the main concern? Or things like the 'tone' of the noise etc?
