How much do noctua fans cost there? If they are as low as ~18 dollars, sure, but most places I see have them for around ~25 and sometimes on sale for ~21.
Swapping out fans is hardly an endeavour, i'd rather buy 3 nexus fans and have to swap them out every few years and enjoy the smoother sound than buying one noctua. i have no use for their 'accessories' either. I can understand the longevity bearing argument, but at the same time noiseblocker fans can be had for ~22 dollars on amazon - better performance and a high quality bearing as well. Likewise, amazon/quietpc stock GTs for less than 20 bob each and come with a pretty decent (2BB) bearing which should last for quite awhile as well
Probably an ignorant comment from me, but aren't Noctua fans higher CFM on average? 120mm fans seem to favor Noctua in terms of CFM vs. equivalent Delta fans (and I'm not talking about high RPM PWM fans necessarily, more like various case fans).
I have gotten a fair number of Noctua fans for <$19 over time, some as low as $13 on "used like new" and sale deals. They are definitely not absolutely silent, but I can actually keep them at max RPM without hearing much of anything, vs. other fans that would be quite loud at max RPM. I also really liked my NF-F12 PWM, which unfortunately was sold with an old computer, and thinking about getting more for a future radiator, unless I find better noise/cfm/static pressure for just under $20.
A lot of the quiet fans I see listed seem to also have very low max CFM... at that rate, I just severely undervolt my Spectre Pro fans, and they are also super quiet. They just don't end up moving that much air.
I'm not sure how accurate their cfm data is, but in any case they are outperformed in terms of cooling degrees by the real silents - check out the SPCR review of the D14, it has test data on both the stock noctua and real silent fans. I figure that their cfm specs are inaccurate and untrustworthy however, considering SPCR testing has dispelled their dba ratings.
Let's see, let's check out this thing called warranty (which in case of fans cover all non-standard noise) - minimum in my country is 24 months. Noctua fans - 72 months, everyone else - 24 months.
And pricing is very local thing... Noiseblocker eLoops are ~17 euros, Multiframes are 20 euros. Scythe GT is 13 euros, Noctua fans are 15 euros.
Real Silents are 36 months. I don't see it as much of an issue myself, I could've opted for a Seasonic X460 fanless with a 7 year warranty, but instead decided to get the Super Flower. Warranty is shorter, but it's also a much better unit. Plus, it's not as if there's no innovation in fans - Noctua themselves are releasing some new fan with some new technology in the near future, according to SPCR news. By the time 6 years are up, there'll be more attractive items on the market
I'm going off NA (ncix/newegg) and British (quietpc) pricing. How much are Real Silents there?
