As those of you who have owned these will probably recognize, these were purchased with silence as the primary consideration, as I had never experienced cooling fans with such low noise levels, and I was unfamiliar with what the CFM numbers really meant with respect to the actual cooling performance, as well as the good old hand-in-front-of-the-fan subjective test of cooling power.
To begin with some generalizations, the bottom line is that Thermaltake makes quiet, relatively powerful fans, that Antec had given up far too much power for the sake of silence (silence is useless if it can't cool worth a damn), and Coolermaster's product in question wasn't a master, but a competent apprentice.
Both Antec fans were absolutely useless at the low setting. The airflow is barely noticeable with your hand in front of it. If your hand isn't very sensitive, you will probably not realize it's on except for the blades spinning. It's quiet, but USELESS. It couldn't cool a tenth of a degree that mere exposure to the ambient air won't do. Despite its minimal power consumption, the airflow is so incredibly weak, it must be WARMING the target, rather than cooling. Both Antec fans on the low setting are incredibly quiet, but silence is useless with zero utility, and there's no way any honest person would rate these above 0.49 out of ten, so one must necessarily round to zero. These are losers, without question.
The Coolermaster was significantly louder, but not nearly as loud as most fans sold prior to this decade, so it was a competent, if not impressively quiet, option. While the word 'SILENT' in the title is misleading, and you can definitely hear this fan even across a reasonable-sized office or living room, provided it's an otherwise quiet room. Within ten to twenty feet, there's no question it's on (again, in an otherwise quiet room), and I wouldn't want it within a couple of feet of my ears with a clear line of sight for longer than a quarter hour at a time. That's a recipe for slow, but certain, hearing loss. Having worked in a class 10 cleanroom, and suffering from that tinnitis ringing that happens when one suffers from permanent hearing loss (thanks a lot, Intel & Micron!), I have no desire to ever make things worse, and the Coolermaster, so long as it is properly placed, is a decent option, although far from the best. But when one factors in its price, it cannot be ignored. If you have need of a 140mm (14cm) case fan, this is a good option, although it lacks speed control. It's either on or off.
Now as for the LED lighting, it's a pleasing tint of blue, and it is rather bright. If you want to use this in a room that needs darkness (such as your bedroom or a home theater room), you might want to keep it under wraps, because the LEDs are bright enough to distract in dark environments. But if you want that light, this is a great option.
Thermaltake shines in this case, as their fans were decidedly quiet, yet offered a decent amount of airflow even on the lowest setting (more than the Antec fans on low, that's for certain!), and a surprising amount on high, while being more quiet than the Coolermaster. The Thermaltake ISGC Fan 12 (AF0018) was the star of this roundup, and its silence (especially at lower speeds), adjustable fan speed, and excellent airflow (at those noise levels) set a 2012 standard, IMHO, in 12-14 cm 'silent' fans available at Amazon in January of 2012. I purchased another copy of this fan, and if they were still available on Amazon.com, would have purchased two more this month. I still plan to purchase another Thermaltake Mobile Fan 12 External USB Cooling Fan 12CM AF0007 (that's an incredibly useful fan, especially if you're cooling hard drives, in an enclosure or open in a docking bay of some sort, or for cooling an overheating laptop), in addition to newer offerings from competitors (Antec included) to see if they've increased the utility of their offerings.
So in closing, the Antec TrueQuiet 120 & 140 were disappointments, and even if you get them at a discount, you will regret your purchase unless you didn't need to cool anything, which is the purpose of a cooling fan. Avoid the Antec TrueQuiet 120 and 140, but I have yet to test the 'Pro' model of each which was released on February 6, 2012, but its specifications likewise fall short of the Thermaltake ISGC Fan 12 (AF0018) by 12 CFM on high, and putting out 2.8 dB more noise on high. It's too bad the Thermaltake ISGC Fan 12 (AF0018) is no longer available. It was a silent cooling superstar in the 120mm form factor! And finally, the CoolerMaster 140mm blue LED silent fan isn't quite silent, but at under ten bucks, it's great, competent, and while it has no speed control, if it's shortcomings are accounted for, it makes an excellent case fan.
When I replaced the Peltier element (TEC1-12706), I decided to use this fan because it was silent and moved about 60 CFM. And the current draw at 12V was not substantially greater than the original fan. I attached the fan to the metal heatsink using zip ties (pulled REALLY tight). The blue LED that lights up when the fan runs matches the blue LED display on the front panel of the wine cooler. I had to make a simple wiring harness because this is a three-pin fan, and the wine cooler uses only two pins. So the fan runs at top speed when it is on - but you cannot hear it.
The wine cooler has worked fine for two years now with the replacement fan. It performs to factory spec - reaching 17 degrees Fahrenheit below room temperature.
This Cooler Master fan is insanely quiet while also having a great CFM rating, its a good ratio middle ground for most. The box comes with the four required screws, a short manual, as well as a 3 pin fan to molex adapter in case you have run out of motherboard pins. I cant say much else as this is a straightforward and simple product, but I do highly recommend it.
I hope that I was able to help someone in their purchase decision.
Powered and controlled with a NZXT Technologies Sentry Mix 2 Fan Controller hooked up to two Coolerguys 100-240v AC to 12 & 5v DC 4pin Molex 2A Power Adapters
The blue LED light is an even dark blue coloring and not the cheap LED lights that just sort of glare across the fan blades. They are 120 mm size fans and they have sleave bearings for long life and performance (30,000 hours rating).
These fans were easy to install and the look great. These fans are a good buy for a high quality fan at a low price!
