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.

IMO the most important revelation of this review/roundup is:LOUDER = BETTER COOLING
All else being equal, that is a fundamental fact that cannot be avoided. Sure you can push results one way or another with smart fan choice, but the fact remains that higher airflow (with static pressure, when used with restrictive rads) makes for better cooling as well as higher noise.

"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."With all due respect... You tested six fans. Six. The Corsairs count as one, Captain Fan Control. Worse yet, only one of the models was actually designed for heatsink application, in a market where there are numerous others.
Oh yeah, the Silverstone's spiral grill is designed to PROJECT AIR ACROSS A DISTANCE. It's a case intake fan. C'mon.
Love ya, Dustin. Really. Do some research, gather some appropriate fans designed for or at least with a strong reputation for hsf use, and ask around about modern test methodology. Fan reviewing is a pain, I know. There's no convenient benchmark program for it. Here's one tip: Get access to a LongWin machine. If Linus at NCIX can get to one (http://www.youtube.com/watch?v=9uUXt7mE6Qg&fea... so can the web's preeminent computing site (that's you guys, bro). If you want credible fan analysis, you need data from professional equipment meant for it, not "Grandma's Blog" style guesswork.
Yes, fans matter, a lot; a fact that is being increasingly recognized. Thanks for getting on board. =)

As many have already pointed out I would really have liked to see some of Noctua's fans in the roundup as well as a couple of the Be Quiet! fans which at least on paper look pretty good. From a price perspective they seem to be in the same league as Noctua.DustoMan - Friday, August 24, 2012 - link
Thank you for doing this roundup. When corsair came out with those fans, I through about swapping out the stock fans on my H80. Now I know to just save the time and money!MeanBruce - Friday, August 24, 2012 - link
Anyone that is using the NF-F12s with the LNAs 12v drop down inline attenuators is completely missing the entire boat here.The NF-F12s are PWM fans, in PWM mode with a PWM fan controller either outboard or installed, will run a full range of 1200rpm way down to an inaudible to the human ear 300rpm or any other thermal/rpm profile the user wishes it to be.
Do some homework, then trial and error before posting, and Anand not including these fans is outrageous. Why come here.
1200rpm – 300 rpm. Mix it up and love your rig much more.
Get them airbrushed RED and BLACK, to avoid the hidden brown ad nauseam.
This just in from Noctua:
“The best way to adjust the speed of your pwm fans will be to either connect them to a 4pin mainboard fan header or to use an external fan speed controller that supports 4pin pwm fans. Because while it is possible to reduce the fan speed by lowering the voltage, only using them in pwm mode will allow you to get the fan speed as low as 300rpm.”
Kind regards,

“I'm sorry, but I can't recommend you a specific fan controller.
However it might be possible to use multiple splitters (included with the fans) to connect your 3 fans to one channel/controller. Our NF-F12 fan is rated at 0,05A or 0,6W, which is quite low compared to other fans and therefore the fan controller should be able to handle 3 fans with in total 0,15A or 1,8W; but please check this with the fan controller specs or manual to be on the safe side.”
Kind regards,
Alexander Dyszewski

“At 300rpms for the NF-F12s, 6 to 8dB sounds about right, we didn't publish the values for minimum fan speed, because it gets difficult to make reliable measurements at such low noise levels. In real world terms the NF-F12 is inaudible when spinning at minimum fan speed.”
Kind regards,

These articles is why this site is on my favorites bar. Thank you!Capt Proton - Saturday, August 25, 2012 - link
I finf this review unworthy of the usually high standards Anandtech has represented to me. Not including such obvious choices as Gentle Typhoons and Noctua's is an extremely puzzling choice. If one follows threads on fans for either air or water cooling, it is obvious that the Gentle Typhoon's are certainly one of the most popular. Not to include them opens the possibility of a hidden agenda, though I am not sure what that may be.random2 - Saturday, August 25, 2012 - link
It always amazes me when I see reviewers overlook very good and very popular products. Yes, I'm another damned Noctua fan. No pun intended. :-)n13L5 - Sunday, August 26, 2012 - link
Its a very small selection of fans to start... fans are cheap, could have really gotten some more, including the Noctua, Alpenfoehn, Thermalright, Noiseblocker, Phanteks, Papst, BeQuiet, Xilence...And then, why oh why are you calling 30 dB your noise floor???
In my room, which has some sound damping, but is still far from an anechoic chamber, I've measured down to ~10 dB.
When people set up their systems with enough fans and well tuned automated fan control, they can get a gaming system that's below 15 dB during office work and still stays around 20 dB during gaming, given the right GPU choice, like Gigabyte's 3 fan OC Windforce series.

Would also liked to have seen my lovely Silent Eagle by Sharkoon. Dimples ftw!
