Choosing the Best 120mm Radiator Fan: Testing Eight Fans with Corsair's H80
by Dustin Sklavos on August 23, 2012 12:01 AM ESTCorsair H80 Stock Fan
When I met with Corsair, I asked them specifically which fans they would recommend using with the H80 since they had just released their new SP120 line. Surprisingly, they suggested that unless you're going for extreme silence, the stock fans that come with the H80 would provide the most balanced performance. Part of the reason for this is that the H80 has a built-in three speed fan controller that can change settings just by pressing a button on the waterblock; you can read more about it in our review of the H80 itself here.
| Airflow (in CFM) | Static Pressure (in mm/H2O) | RPM | Rated dBA |
| 46-92 | 1.6-7.7 | up to 1300 (Low), 2000 (Medium), 2500 (High) | 22-39 |
Our own testing with the H80 on its own revealed a decent range of performance, with the Medium setting seeming to be the ideal one, but we'll be able to compare them to a broader range of fans this time to see if the H80's stock fan continues to be the best choice.
Corsair SP120 Quiet Edition and High Performance Edition
The "SP" in "SP120" stands for "Static Pressure"; Corsair recently released a series of fans geared for radiator and case use, with the SP line targeting radiators. The designs are fairly slick, with removable colored trim and rubber mounting posts to mitigate vibration noise. The Quiet Edition has its fan speed capped and is designed, as its nomenclature suggests, for quiet operation. Meanwhile, the High Performance Edition runs at a higher speed and produces more noise as a result.
| Fan | Airflow (in CFM) | Static Pressure (in mm/H2O) | RPM | Rated dBA |
| SP120 Quiet |
37.85 |
1.29 | 1450 | 23 |
| SP120 High Performance | 62.74 | 3.1 | 2350 | 35 |
The rated performance of these fans is interesting, especially taking into account the SP120 Quiet's specifications actually being lower than the lowest setting of the H80's stock fan.
SilverStone Air Penetrator AP121
It's interesting to note that this fan has been the subject of a lot of debate on forums as to how fit it is for use as a radiator fan. SilverStone advertises a high static pressure for the AP121 and its grill is designed to direct air, suggesting that it would be a potentially ideal radiator fan. At the same time, its grill also potentially obstructs a decent amount of airflow.
| Airflow (in CFM) | Static Pressure (in mm/H2O) | RPM | Rated dBA |
| 35.36 | 1.71 | 1500 | 22.4 |
The AP121 isn't much for airflow, bested even by the quiet SP120, but it sure fires that air with a decent amount of force. This is going to be one to watch; it should be a strong performer due to its solid static pressure, but we'll see.

That at least half of you have a fan you're upset wasn't included, and they're almost all completely different fans. There was no way I was going to be able to cover all of them (although the Yate Loon, Noctua, and Scythe are admittedly pretty big omissions, especially the Noctua), but I seem to have opened Pandora's Box with this one.This roundup is a little unusual for us (but then I'm the unusual review guy at this point), so if it does well I'll look into updating it with a second part in a month or two with a second set of fans. Noctua's reached out to me, so the possibility is there.

If you do a second round you might want to consider the following fans, too. Looks like Austria (Noctua) and Germany (Noiseblocker, be quiet!) have a bit of a fan industry going...http://www.bequiet.com/en/casefans/270

The people at Noiseblocker have also just released a new fan series based on research funded by the German ministry of technology. Basically, the blades are connected on the outside to a ring that rotates in the chassis. So far, they don't even seem to have a page in English about it:

I'm using the low-speed ones as case fans, but that's beside the point I guess.

It was great seeing Anandtech reviewing fans, especially since the which "which fan is best " discussion is certainly fiercly debated by enthusiasts on forums.Great first step and definetly +1 for a second round up with more fans!!

Personally I find Arctic Cooling fans to be a solid choice. Not sure how they're available in the US, though.sicofante - Thursday, August 23, 2012 - link
Maybe research a little bit what makes a fan have good pressure, then proceed.Usually, many fins with little space in between say "high pressure"...

Dustin,I posted another reply as I didn't see your reply right away. I appreciate the hell out of you trying this in the first place. I love reading Anandtech and come here most for builds, advice, or to browse the forums to see what everyone is doing with their rig's.
I think you did indeed open Pandora's box, but having said that I think a different poster is correct in saying that this is a welcome addition to other articles here at Anandtech. Much needed and many people do prefer water over air. I, myself, just bought and installed a H80 with my recent upgrade to my rig.
Keep up the good work and I certainly look forward to a part 2 of this.
Cheers!

I would also mention based on the sheer numbers of comments there is a definite reason to do a part 2 as so many people seem passionate about this area. Least you could pitch that to your editor that way!!!nubnubbins - Thursday, August 23, 2012 - link
I think the issue is that you have a random hodgepodge of fans included while passing over fans widely regarded as some of the best for radiators. As a baseline, you should have had a Yate Loon and Scythe Gentle Typhoon AP15. Yates are widely regarded as the best budget fan and AP15s the best lower noise rad fan. After that, the Cougar Vortex, Aerocool Shark, Gelid Wing, Noiseblockers, Noctua NF-P12 and NF-F12, and XSPC Xinrulian fans are all regarded as great radiator fans by the likes of MartinsLiquidLabs and those in the water cooling community.It's nice to see some fan reviews, I think people are just disappointed that the staple radiator fans were left out and you had a disproportionate number of Corsair fans instead.

Geez guys, calm down a bit! ;) Testing every fan on the market is more or less impossible. While I personally would have loved to see the Scythe/Nidec Servo GentleTyphoon make an appearance (especially since they're somewhat more obscure than they deserve), but the purpose of this article is not to crown "the best fan ever".It is supposed to showcase "a good fan" for the job. Clearly there will be other good fans. Some may even be a little better. But so long as you're giving a customer a recommendation that's in the top 20% of products on the market, backed up by hard data, that's already going to help that customer a whole lot than forum posts stating "I can guarantee you that fan XYZ is the best, I have been using it for years". Because all that a post like that states is "I have not compared my fan to others in years and actually have no idea how good the competition is".

There's nothing wrong with people mentioning fans. In fact, it can be helpful as it gives Anandtech an idea of what people would like to see. They can take the mentioned devices, review their stats (and maybe even existing reviews) and possibly create another line-up.Although, frothing rage is never appreciated, but I think people have been pretty civil. =)
