Truequiet 120 Cooling Fan With 2speed Switch

Don't get me wrong based on the title of the review, I love Antec products in general, and am not doubting the quality of the product.

First thing I did when I got home was to plug one of these suckers in with a AC-to-molex power adapter, just to see how quiet these bad boys really are. I was definitely impressed in that arena since I could only very very faintly hear the fan unless I put my ear right up to it, even on the high setting. Decked out with a few of these you WILL be able to tell if your computer is on or not, but unless you are explicitly paying attention the noise level will fade perfectly into the background.

That said, the reason I say that this fan has limited usefulness is that it's cooling power vs. other fans can't even compete. I had originally purchased 6 of these on a whim to replace the stock fans in my desktop, which is in an Antec Twelve Hundred case that comes stock with 5 x 120mm TriCool fans and a 200mm fan, and sounds like a jet engine with the fans on medium or high. I had assumed I may be sacrificing SOME cooling power for the noise reduction, but wasn't too worried because the average temperature inside the computer is pretty good compared to numbers I've seen for other comparable setups. Foolishly, however, I didn't bother comparing specs until I had gotten home, which (using specs on the product packaging) goes like so:

TriCool:
Low - 1200 RPM / 25 dB / 39 CFM* / 1.56 CFM-to-dB
Medium - 1600 RPM / 28 dB / 56 CFM / 2 CFM-to-dB
High - 2000 RPM / 30 dB / 79 CFM / 2.63 CFM-to-dB

TruQuiet:

Low - 600 RPM / 8.9 dB / 21.5 CFM / 2.41 CFM-to-dB
High - 1000 RPM / 19.9 dB / 35.83 CFM / 1.8 CFM-to-dB

*Cubic Feet of air moved per Minute.

So, not only does the TriCool fan have unquestionably greater cooling power, but the amount of cooling per decibel of acoustic noise actually scales upward with increased RPM, in contrast to the TruQuiet model which scales downward.

So, in conclusion, these fans are definitely a no-go for a enthusiast, gaming, or other high-performance computer. However, if noise level is more important to you, whether you just like a quieter machine or your application makes it mission-critical (another reviewer was using them for equipment in a recording studio, for example), these are probably just the thing you need. They would probably also make just dandy replacements for the stock fans in most pre-configured desktops from HP/Dell and the like.

I have a Recording Studio/Photography near Brooklyn
and I needed a Quiet Fan for my External hard drive case.
I purchased two fans, but they were noisy like two helicopters in the house.
After buying this (Antec TrueQuiet 120) I was doing back flips.
It is so quiet I had to double check to make sure the fan was spinning.
The unit has a switch on it for High and Low speed reducing the already quiet fan to even quieter.
This is great.

This is the quietest fan I have ever owned, I bought 2ea. for My computer that I just built
(ASUS P8P67 MB with Intel i5 2500K OC to 4.3ghtz with Radeon HD8670)and really wanted something VERY quiet that would keep my computer cool as it is Overclocked, well as it turns out these fans have little air movement for my likes on this set up :)

That being said - these are VERY well made fans, and I love the silicone grommets to reduce noise only minus 1 star for not being able to kick into a higher speed to satisfy my need for more air movement

However I now use the True Quiet 140mm for my entertainment stand to cool my equipment as you cannot her them and move just enough to make a big difference as I cut holes in the bottom of my shelves under my equipment then installed a 12 VDC plug-in power supply in to my switched AC 120 outlet so when the AV receiver comes on so does the Antec fans :)

I think these are ideal for any computer that you would like to install a VERY quiet fan in a computer that is not used for gaming or Overclocked.

If you are like me, I really had a Hard time finding a fan that would fit LOW noise level with higher output, and I believe I have found a much better fan for my computer so thanks the the great reviews on Amazon I purchased 2ea. Aerocool Shark 140mm Blue Edition RPM: 1500 RPM with Air Flow: 96.5 CFM (over twice the air movement)Fans for my Gaming computer to mount into my 690 Cooler Master case - very happy with both my purchases as i did not waste any money :)
