Added more info after having actually tested both fans on my Sapphire RadeonHD 6570

Mar 11 '15 at 18:55 comment added MoonSweep I thought so, that's why I'd rather trust theory, and ask the experts ;)
Mar 11 '15 at 18:45 comment added Air If you think the difference in noise level won't be measurable, then it's even more likely it won't be noticeable, in which case you probably don't have a reason to measure it in the first place.
Mar 11 '15 at 18:37 comment added MoonSweep And, beside spending 40 bucks instead of 20, another reason is that the CPU fan noise would probably cover the GPU's one, so I could accurately monitor the tempearature from the thermal sound inside the GPU, but probably not the noise level.
Mar 11 '15 at 18:34 comment added MoonSweep I thought about it, but switching fans would also mean unmounting the whole heatsink assembly, cleaning/applying thermal paste, etc etc, at least twice. I'd like to avoid that, I already cleaned it up from the old thermal paste (which was all hardened; I rubbed it with a credit card and cleaned with 90° alcohol) and now the board is all clean, just waiting for a replacement fan. Althouhg the results sure would be interesting, I really don't feel like messing up and cleaning the board again two or three times (even if the thermal paste won't be hardened like the old one was).
Mar 11 '15 at 18:10 comment added Air I don't suppose you'd care to buy them both, do a comparison test, and then share your findings? ;)

A side-by-side image of the fan blades will be really helpful for people reading this question. Some details are unnecessary. Title needs to be explicit and relate to our scope as an engineering site.
