Cooler Master Seidon 240M and 12 More Coolers: The Retest and Mega-Roundup
by Dustin Sklavos on April 26, 2013 6:01 AM ESTThe Noctua NH-U12S and NH-U14S
Noctua shipped us a shiny new pair of recently launched coolers designed specifically to be used in systems that have RAM with tall heatsinks. They're both pretty interesting beasts in their own rights, particularly because they're just...not the exceptionally beefy high performance air coolers we've come to expect. Or at least they don't look it.

The smaller of the two is the deceptively plain-looking NH-U12S, which sports one of Noctua's standard 120mm PWM-driven fans. Noctua includes clips that allow you to attach a second 120mm fan, but in testing the benefits were negligible at best, offering a substantial increase in noise for 2C better performance at most. Note that these coolers aren't yet available on NewEgg, but are clearly meant to replace older versions that use Noctua's older mounting scheme. The NH-U12S has an MSRP of ~$65, so despite its small stature we're still not in the realm of entry level.

This monster is the NH-U14S, which uses Noctua's special NF-A15 PWM fan. This is a 150mm fan designed to occupy the same space as a 140mm fan, but uses 120mm fan mounting. Given that it's a larger fan that can be mounted in smaller spaces, it's interesting enough unto itself, but here Noctua pairs it with a heatsink designed to take advantage of its unusual profile. This one also accepts a second fan, but like its smaller sibling, sees no real benefit from it. MSRP is a more punishing ~$75, and unlike the NH-U12S, the NH-U14S can and will intrude on the top PCI Express slot.

Both coolers come with Noctua's new "SecuFirm 2" mounting kits for both Intel and AMD, and the packages on the whole are of excellent quality. The clipped on fans are both secure and easy to remove and replace, and the backplate is easy to mount. In both packages, Noctua includes a healthy amount of extras: a PWM splitter for adding a second fan, clips for adding a second fan, ultra low noise in-line adapters, and their own thermal material. The instructions are also detailed and full color.
Noctua products are, facing facts, fairly premium stuff. They have premium prices, but thankfully they feel high quality. Everything about the presentation is top notch. The high class presentation seems to be common with some European companies; Swiftech's package for the H220 is extremely smart, with the cooler already assembled, fans already attached, and pretty much ready to be mounted. Likewise, all of the be quiet! gear I've tested has come with a healthy amount of accessories for the cat to steal.

This article was to test the performance of the coolers at a certain clock speed. However, I think you would find that when pushing the overclock higher you would see some coolers wouldn't be able to keep the temps in check while others could. There's a difference between efficiently transferring the heat and the amount of heat capable of being transferred. That's why the D14 and TRUE are popular among overclockers who push higher than what we see in this test. To that end, the 240mm or 280mm closed loop coolers will also be able to handle higher overclocks.In this (http://www.overclock3d.net/reviews/cases_cooling/s... review of the H220, you can see that on the socket 2011 cpu the air coolers weren't able to maintain the extreme overclocks like the closed loop coolers could.

sorry, link broke. http://tinyurl.com/cu24bwk That should work better :)epoon2 - Friday, April 26, 2013 - link
You meant that as the load/watt/heat produced by CPU increases, the order in this graph http://images.anandtech.com/graphs/graph6916/54390... changes?but in the above test, the fans are at constant, max speed already ... I know what you mean but I just can't figure out the science/reason behind why your scenario would happen.

Two key factors are at play:1) the amount of watts of heat the solution can dissipate at a given delta temperature to the air.
2) the thermal interface performance to the CPU itself and hence what temperature the CPU is running at.
Water is cooling the water block but then water itself is above ambient temperature. This often means the ambient temp CPU effectively sees is higher compared to what it was with air. But water warms and cools much faster than air by volume, and it can hold a lot more energy. Combining water with a substantially larger area to exchange its heat to air and you get a solution that cools better given a large number of watts of heat but does less well on low wattage where air cooling fits and is sufficient.
A 2600k pulls about 170W over clocked. A 3930k can be over 300W. 170W is about the point to consider water but you need an overspecced loop to show any advantage at all. Passed 200 watts however and water takes a clear lead and air stops being able to do the job.

Assuming the water pipes dissipates negligible heat, the role of the water system is equivalent to that of the thermal compounds: to transfer energy and heat to the sink and radiator.The difference in rate of heat exchange between the metal pieces and the external environment becomes the key.
In an open air test, the rankings should remain the same as amount of heat generated by the CPU increases. In the real world , the performance of air coolers depends on the effectiveness of the case's heat exchange system..

For future reviews, I wouldn't mind seeing the Xigmatek SD1283 tested. A lot of people recommend it for people who want something better than the CM Evo but don't want to spend Noctua money. It typically runs ~$50 so it fits that niche price-wise as well.A5 - Friday, April 26, 2013 - link
I guess I meant the silly-named "Dark Knight 2" when I wrote this. Didn't know they had 2 different SD1283s. Guess I wouldn't mind seeing the cheaper, non-coated "Gaia" as well.Dr_b_ - Friday, April 26, 2013 - link
Does the U12 have socket 2011 mounting capability?epoon2 - Friday, April 26, 2013 - link

thanks 4 link. NH-D14 is really too big, blocks a socket in my x79-UP4 gigabyte. U12 looks like it might work here.
