Choosing the Best 120mm Radiator Fan: Testing Eight Fans with Corsair's H80
by Dustin Sklavos on August 23, 2012 12:01 AM ESTConclusion: Fans Can Matter
So what information are we left with after this roundup? Regarding the Corsair H80 specifically (and presumably the rest of their line), you're probably best off just sticking with the stock fans included with the radiator as they provide a competitive blend of performance and acoustics. Those of you not using the H80 will find yourselves surprisingly well served by Corsair's two dedicated aftermarket radiator fans, as they're both fairly competitive.

While most of the fans we tested did bunch up thermally, they separated a bit more when acoustics were taken into account. The frugal shopper looking for balanced performance from a radiator fan is probably going to want to try and track down the NZXT Performance fan; NewEgg doesn't have it available at the time of this article, but Amazon is selling it for just $6.99. Alternatively, the Nexus Real Silent D12SL-12 is an old standard but still an excellent performer; anecdotally it runs a bit quieter than the NZXT, though you'll pay a bit more for the privilege.
Meanwhile, BitFenix's Spectre Pro proves to be a jack of all trades and master of none. SilverStone's Air Penetrator AP121 is a fine fan but doesn't produce performance consistent with its acoustics. And amusingly enough, CoolerMaster's SickleFlow's grossly exaggerated specifications fall apart in practice as it proves that it's entirely possible to buy a bad radiator fan. I actually nearly burned myself on its plastic housing when I went to remove it.
What may be most disappointing about this lineup, though, is the unfortunate fact that there may be no magic bullet radiator fan that's able to produce stellar thermals with low noise. We can get close, but the reality is that we need to be moving more air at a faster rate to start hitting the limits of the pump and radiator, and that means more noise. If you're comfortable sacrificing a few degrees for a peaceful system, though, NZXT, Corsair, and Nexus all at least seem to have you covered.

TerribleIgnoring the questionable quality of the single pass radiator, or that of an all in one rad, I'm not sure where you pulled those results for the sickleflow, because it's well known that those fans are excellent for radiators. Something isnt right here.
I would stay away from the noctua nf-p12 if youre going for a heavy oc, they are okay in dual or triple pass rads or in non-oc sitations, they just dont cut it.

I found a (french unfortunatly) test here : http://www.hardware.fr/articles/867-15/noctua-nf-f...of NF-F12 PWM, it seems they are also testing it on radiator...doesn't look so great compared to others, especially when you consider their price.

I loved the French article or rather the translation: much more fun not quite knowing what's meant.But numbers are the same in any language and the clear winner was the Cooler Master Excalibur; which left favourites like the Cougar Vortex, Arctic Cooling, Scythe and Noctua for dust. And yet it doesn't appear on anybody's list of 'best fans'. It's number 1 position is also borne out in this very pertinent review http://www.techreaction.net/2011/12/20/water-cooli...
Which goes one step further than the French article, rather than just measuring air flow through a radiator (or not) measure the resultant temperature drop. Which after all is what it's all about (Yes, I go for performance over noise, within reason, I don't want to sit next to a hoover).
But what's most interesting to me about the techreaction article is that ALL the fans are within a 3 Celsius of each other.
Which tells me that there's really not much difference fans.
OK, there's only 15 fans reviewed, and there's no 1.99 'fan-u-like' fan reviewed; but there is a 3.99 Yate Loon which holds it's end up admirably.
So bottom line is: it's no disaster which fan you stick on your cpu cooler.
But as we all know, a 3 degree cooler cpu is a happy cpu.
Though yet again the 3.99 Yate Loon D12SM-12, has to be a no-brainer (if you can find someone who will sell you ONE).
Then again the Cooler Master Excalibur is 1.8 degree cooler...

i agree with other commentators. this is a really interesting article, and helpful. dustin is on point again.would love to see the scythe, noctua and thermalright fans reviewed. particularly interested in thermalright since their silver arrow has led the pack in air cooling, and they are known for performance w quietness throughout their line.

Specs given by fan manufacturers (just like specs on flat screen TV's) are COMPLETELY MADE UP. I'm glad this story was written so more people can learn the truth. Here's another source of information on the subject:https://www.youtube.com/watch?v=9uUXt7mE6Qg&fe...
Also another way they mislead the consumer is by perpetuating the idea that fans are built for CFM *OR* static pressure. Physics says as CFM goes down pressure goes up and vice versa. So a good fan will be good at *BOTH* CFM and pressure, not one or the other, just more misleading marketing.

sry double post. someone delete pls.LoneWolf15 - Sunday, September 9, 2012 - link
Both Noctua and Scythe apparently didn't make the cut. People here have already commented about Noctua, so I'll talk about Scythe. What, no Gentle Typhoons? They aren't cheap, but they're darned fine fans. I use Scythe S-Flex (FDB) fans as well, but the Typhoons are probably better for radiator use. Seeing as both Noctua and Scythe are highly regarded in the enthusiast crowd, I'm disappointed to see them missing in action.cronos1013 - Friday, September 28, 2012 - link
Dustin,OK so by doing this article and ignoring the 2 fans widely recognized as the best radiator fans on the 120mm market, you are showing how little credibility you have in this area, and how you didn't really do ANY research before going about testing these.
It's time to suck it up, buy 2 more fans and rerun these tests...because come on...nobody wants to know what the best of the under performing fans for radiators are.

but what about fans that aren't mounted against one? Surely they will produce different noise than one pressed against a radiator.
