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.

are these really the delta temps in Celsius above room temp? if they are then even at a room temp of 21.11C (70 F) you have gone way beyond the temp spec on the processor(72.6C at the heat spreader) with several of your air coolers....even if these are absolute temps Celsius some of the air coolers are dangerously close to max temp. I understand pushing the overclock to test the coolers, but subjecting the chip to those temps is bound to kill it a lot quicker. i suppose if this is all you use it for it doesn't matter much, but damn i would hate to do that to a chip i paid for.Bobs_Your_Uncle - Friday, April 26, 2013 - link
I've remained extremely intrigued with both the design & the potential efficacy of a prototyped cooler noted within Anandtech ( http://forums.anandtech.com/showthread.php?t=21782... ) & elsewhere ( http://www.tomshardware.com/news/cpu-cooler-sandia... --- https://www.youtube.com/watch?v=JWQZNXEKkaU ). It's been quite some time since initially publicized & I wonder if you might know where to research for an update on it's status?While the concept has many possible applications, the thought of it's implementation for PC component cooling is enough to excite one into debilitating nervous ticks. (Well, maybe it's not quite that exciting, but ..... I'm still interested on where it is in development!)

Hey Dustin, where's the H110? I understand you'd like to limit the test to 'current' coolers, but the H110 is still readily avaialable at retail, and it seems coutnerproductive not to include what should be the top performaing CLC is this roundup...Dustin Sklavos - Friday, April 26, 2013 - link
The H110 and Kraken X60 are almost the exact same product, just different fans (understanding that Corsairs fans are superior) and different control (the Kraken X60 uses USB and software, the H110 relies entirely upon your motherboard). But they're the same Asetek radiator and I suspect the same pump.Guspaz - Friday, April 26, 2013 - link
I recently tried to replace my Shuttle's 92mm fan with a Noctua NF-B9 PWM, which was a very disappointing experience. Yes, it was quiet, but it also spins extremely slowly at max speed, with a low static pressure and a very low airflow. The end result was an increase in CPU load temperatures of 40 degrees (celcius) or so, which is pretty damned massive. Since the CPU fan in a Shuttle doubles as the case fan (the CPU has a heatplate which connects via heatpipes to a large heatsink on the rear of the case, onto which a 92mm fan blows air through it, cooling the CPU and exhausting air from the case at the same time).The problem is that the stock fan, while decently quiet up until 35-40% speed, has this point around 40% speed where it very quickly gets very loud (motor noise, not airflow noise). Some research showed that there are only a tiny handful of fans on the market that spin anywhere near as fast (Delta had one, that's about it), and they're a tad pricey to buy on a "hope it's quieter at medium speeds".
Is it really so much to ask for a fan that is quiet at lower speeds, but can still spin fast (loud if required)? I don't care how loud the thing is at max speed, because if I'm gaming I've got headphones on anyhow. But during normal use (or while trying to sleep) the occasional CPU spike pushes it just past the 40% mark and even the 5% speed bump causes an audible revving.

to your point on quiet at lower speeds, but can still spin fast (loud if required) -It would be more expensive, and the fan may be larger, and the original target audience would flock because their original wish was getting a quiet fan at all times.

I'm a bit out of the game, but I think the Noctua fans that only have 6 blades, spaced quite far apart, have a reputation for low air pressure and don't work well when the CPU heat sink has lots of closely spaced fins. I also use a Noctua fan (see below), but it's a model with more blades and more closely spaced ones.In general I agree with you. Fans that run at low speeds by default are a silly marketing phenomenon, which are only useful when you don't have a fan controller, no motherboard fan headers or can't get to grips with the freely available Speedfan program. What you really want is a fan that will still actuate and won't stall at low speeds (say 600RPM), but can ramp up to (much) higher speeds, if needed.
Another phenomenon I find with my own fan / case combination is that there are certain speeds where the fan noise takes on a distinct and annoying pitch. I don't think it's motor whine, but perhaps some sort of whistling effect produced by the fan holes in the case. This happens at 1,300RPM and around 1,050RPM for me, but neither at 900RPM nor 1,200RPM. I therefore find it very important to be able to regulate the fan speed.

I would like to see the replacement of fans with 9 blade fans and see if a lower rpm and higher air flow makes a difference. I took two 9 blade fans in push pull on a Corsair 80i on a i7 3770 because the stock fan noise was so loud/bad. Possibly with this is what I used in push pull from newegg >>> COUGAR CF-V12HPB Vortex Hydro-Dynamic-Bearing (Fluid) 300,000 Hours 12CM Silent Cooling Fan with Pulse Width Modulation (Black)FH123 - Sunday, April 28, 2013 - link
Are there any fan ducts still on the market? I built my PC years ago using a Thermalright HR-01 with the optional fan duct that connects the heatsink to the rear 120mm case fan. This arrangement seems to work very well, which perhaps ties in with your observation that the case fan is very important for air coolers. Fan ducts also seem to be common in commercial designs from the likes of Dell. I don't even use a CPU fan, only the case fan.If it's of any interest, my system is built in an Antec Solo case, optimised for low noise. The only fans are the rear case fan, the power supply fan (at the top of the case) and the GPU fan (ATI 5850 radial fan). There is no front intake fan. The Q9650 CPU has a mild overclock from 3 to 3.6GHz, while remaining at stock voltage. The case fan, at 1,200RPM, keeps the CPU within 45 to 50C over ambient during a Prime stress test. It runs at merely 900RPM during lighter loads.

You can easily make your own with cardboard and tape. I've found a three-sided duct to be the best for connecting a CPU heatsink to a rear fan (with the open side facing the motherboard). It still pulls plenty of air through the CPU heatsink, but also allows air to be pulled over the motherboard VRMs.
