Noctua NH-U12F
Unless you are an enthusiast of silence in computer builds and modifications you probably haven't heard of Noctua. CPU coolers from Noctua are not generally sold by the large US etailers like Newegg, ZipZoomFly, or mWave. However, Noctua products are readily available at specialty computer enthusiast shops like Frozen CPU or Xoxide. The Noctua NH-U12F kit retails for around $65, but we have seen it selling for lower prices at a few etailers. The kit includes the Noctua NF-S12 fan which retails for $20 by itself.
The Noctua NH-U12F is packaged in a sleeved box with the Noctua trademark brown and blue packaging. It seems that everything Noctua comes in packaging with variations on this corporate color scheme.
The Noctua kit starts with a heatpipe tower that is very reminiscent of the Thermalright Ultra 120 design. We wouldn't dare touch the "which came first" question, but we do know that Noctua has been refining the basic design of this 120mm heatpipe tower for some time. Since the two Thermalright Ultra 120 models now sit at the top of our comparative cooler reviews, this design similarity certainly raises our Noctua performance expectations. There are also fan wire channels that allow mounting of both front and rear fans on the Noctua if you choose that configuration.
Inside the dark brown box you will find an exceptionally well-protected heatsink, along with everything you need to mount the NH-U12F on socket 775, AM2, or 754/939/940.
The $20 retail S12 fan is also included, as mentioned earlier, and the U.L.N.A. adapter that fits between the fan plug and the board is included for those who want to run slower speeds with the lowest noise possible.
The included accessories abound with thoughtful little touches. Noctua includes a screwdriver that actually fits in the holes of the cooler fins to allow cooler mounting in some of the mount variations. There are even two pairs of fan wire clips included that practically invite the buyer to try a push-pull fan setup. A clearly written multi-language installation manual is also in the package. Overall, the clear parts identification, abundance of mount options, and included extras make the Noctua one of the best coolers we have worked with right out of the box.
Specifications
Our test system is socket 775, but the Noctua NH-U12F will also mount on any AM2/754/939/940 CPU with included adapters.

Wes -- how far does this Noctua cooler hang over the edge of the motherboard closest to the Power supply? Just trying to figure out if I have room. Thanks for the great reviews on these coolers.Bumtrinket - Friday, May 4, 2007 - link
It largely depends on the motherboard - if the CPU socket is close to the top edge, you could have problems if there's not much space between the mobo and PSU. This also applies to the Thermalright Ultra 120 and other similar designs. The design of the heatsink mounting lets you rotate it through 90 degrees, but that's not the preferred orientation.There's more info at Noctua's site, but they say this in the FAQs:
"How much space between mainboard and power supply is required when the NH-U12 is installed upright?"
"When installed upright (see picture below), the NH-U12 may jut out over the upper edge of the mainboard. In this case, the gap required between the upper edge of the mainboard and the power supply in the case is (depending on the position of the CPU socket on the mainboard) up to 25mm. Measured from the upper mounting holes of the CPU socket, the required distance to the power supply unit is 35mm."

I am a big fan of Noctua, so nice to see their heatsink do as well as i expected.Their fans are very good @ providing a mix of performance & realtive quietness, & it appears this heatsink is no different.
I too would really like to see a TT Big Typhoon added to the reviews, mainly to see how it does compared to the new leaders, something the Typhoon used to be.
I also look forward to seeing your testbed redone with a quieter PSU.

OK, I read this article with some interest, and as usual find the remarks about fanless power supplies completely off-base.I mean, if you're measuring overclocking a CPU, or some high end gaming system, or some high-end Peltier cooler, I could see the point in not using a fanless power supply because such a power supply wouldn't be useful in that configuration. But, I don't buy power supplies with fans anymore, and guess what type of heatsink I go after when I buy them? Yes, very quiet ones. So, when you're testing a heatsink/fan that is made to be especially quiet, or for example, fanless video cards, you SHOULD test with a fanless power supply.
I know most of the reviewers here think shooting space aliens is what everyone does, and they need 600 watt power supplies, but it's just not true. Most people in fact don't need anything that large, so try to think within the market of the product instead of personal preferences. I'm not knocking video games, by the way, they are a much better escape than drugs, or other bad things people do, or even TV. I'm just saying that you guys need to stop thinking everyone does this and needs equipment to handle these foul machines, especially when reviewing items that would never be put in one.

I agree that in order to get more accurate noise ratings a more quiet system based on a fanless psu would achieve higher accuracy. However, anandtech tests have generally catered to enthusiasts and overclockers, and imo, these tests do that well. For starters, they compare cooling performance with noise as a secondary consideration (mainly to see if the cooler advertised is quiet, but as it sates in the article, they are more curious about its cooling/overclocking ability than the noise). Yes, anandtech is using what could be considered a "noisy" test bed, but X6800's and 7900GTX's don't exactly come to mind when I think "silent" pc. Nor do the power, hungry, hot Nvidia 680i based boards. I suggest looking elsewhere for reviews on components that make up silent pc's, such as http://www.silentpcreview.com">http://www.silentpcreview.com. I'll stick with anandtech's review because I could care less about noise if it lets me gain an extra 300mhz out of my processor.TA152H - Wednesday, April 25, 2007 - link
Then why review a heatsink that is focused on being quiet? You completely missed the point. I don't have a problem with them reviewing noisy items, but you don't review a heatsink/fan that is made to be especially quiet, with a noisy power supply or video card. If the heatsink were a cooling beast that didn't pay much mind to noise problems, absolutely go with appropriate stuff. People that want it will not care about noise with the other components. But when someone is considering getting a unit because it is quiet, you don't use a noisy baseline because that same person is likely to look for that same quality in their other components.Ajax9000 - Wednesday, April 25, 2007 - link
Agreed.The "proper" (but time consuming :-) thing to do would be to have a "performance" testbed (which is also investigated for noise as a secondary test), and a "silent" testbed (which is also investigated for overclockability as a secondary test). I.e. people who want "quiet" systems don't automatically excude overclocking, they are just less concerned about it (and vice versa).

Great review and comparison.As an owner of a Scythe Ninja equipped with a silent fan, I can attest to it's effectiveness.....but your batch of reviewed HSF's is missing my personal favorite, the Thermaltake Big Typhoon. It's one of the best at cooling nearby capacitors since the fan blows DOWNWARDS onto the motherboard. I've replaced the original fans for some slower and silent Silenx fans since the core2duo isn't as hot as my old overclocked 820D.
Works awesome good.
Do us all a favor and please include the Big Typhoon (and not it's weaker cousin, the Mini Typhoon) in your review

"We also ran brief test results comparing the cooling efficiency and noise of the Scythe SFLEX SFF21F 64cfm/28 dB-A fan that was used in Thermalright reviews and the SilenX fan used in several of the most recent reviews. Cooling results were similar with either fan on the Noctua heatsink, with the SilenX providing better cooling on some overclocks. Both fans were quiet and came in below the noise floor of our test system, but the SilenX was subjectively quieter than the SFLEX. "REALLY. I have trouble believing this, but I guess we'll find out for sure in the upcoming roundup.
