Worked for a while

Craig S., Newegg
2 January 2016
  • Summary: Was nice when it worked but expected more longevity. Was in a rig that ran 24/7 at stock speeds.
  • Pros: Worked well out of the box. "Quiet" setting was truly whisper quiet. "Extreme" setting dropped temps by another ~5°C but was too loud to have on all the time.
  • Cons: Did not fit as expected in Antec Twelve Hundred case. Had to remove dual rear case fans and mount across both fan housing's area. Cooling noticeably lessened (ran ~10°C warmer) after two years of ownership. Pump stopped working after three years and two months, just beyond mfr's 3 year warranty p...

Extremely Average. Not close to silent

Matthew M., Newegg
6 October 2014
  • Summary: In theory, this fan is supposed to perform well, maybe I got a less than great one, I don't know. It produces a unique drone that doesn't particularly carry well at low but it's quite noticeable at high. So in addition the the air "whoosh" sound you hear a distinct motor drone.
  • Pros: + Built-in high/low speed switch + Decent connection options + Decent airflow.
  • Cons: - Not quiet or silent at all. - It's audible on low and especially on high. However, the interesting thing is that at low the drone that it does produce doesn't travel far. I have other fans going, namely PSU and GPU fans that are louder than this and overtake this fan's unique drone when I step ...

RPM

Brent, Amazon
3 January 2014
  • Summary: I'm not a computer guru, but when I buy a fan that is supposed to run at 800 rpm on low and 1200 rpm on high I take it at face value. It was running lower than both when I first put it in. 300 on low and 600 on high.

Loud, Poor quality backplate

Marco C., Newegg
17 August 2013
  • Summary: I do not think this is a quiet cooling system by any stretch of the imagination. It is actually quite loud. "Intelligent noise / speed control fan for quiet, efficient cooling" I felt mislead by the advertisement of quiet and efficient.
  • Pros: - Small profile pump -Tubing seems flexible enough and durable -Keeps temperatures in average range "ok" -Small enough to fit most systems
  • Cons: -Back plate is very poor quality -Fan is very loud -No RPM sensor for Fan -No fan control by user -Instructions are not very easy to read

The fan is loud

Franco G., Newegg
4 August 2013
  • Summary: I got my system for a little less than it is listed right now. Combined with the price of a second fan, it's still cheaper than a lot of systems that it can compete with. I don't overclock anymore and it's really nice to be able to run my new Haswell in the 30s under load.
  • Pros: Reliable. I have had mine for over 3 years now. It works well. I live in Houston where it is hot as hell. My idle temps were at 50 with stock heatsink. This dropped them down to 28. Stock clock stress test, gets up to 62ish. Overclocked stress test, never goes over 70. Under a more realistic heav...
  • Cons: The original fan is way too loud. 15-20 bucks for a silent fan is definitely worth it. The wire from the fan is ridiculously short.

Good cooler but...

Matthew F., Newegg
1 July 2013
  • Summary: The cooler still works fine, even though its making this sound and is close to two years old now. But its very irritating and makes me wonder if its going to give out soon.
  • Pros: The cooler does what it should and is a good cooler.
  • Cons: Had the thing for just over a year and it started making a rattling sound. Contacted Antec to try and figure it out. Customer support said something was probably wrong with the pump and to provide them with proof of purchase. Unfortunately I bought the product from a different retail store and di...

Good product

Cynthia P., Newegg
17 May 2013
  • Pros: Great cooling ability. Dual fans and thick radiator make for a good kit. Nice pump design with LED light and software makes control very good and easy.
  • Cons: The unit I got had a pump that was suspected with bad bearings. After tilting at different angles to "move" any trapped air I gave up and finally called Antec support. They instructed the unit probably had a bad bearing. I sent the unit back for a refund. The back plate design could use some work...

could be better.

Doug A., Newegg
13 May 2013
  • Pros: Everything works the way it should.
  • Cons: Don't keep temps cold enough for me pretty sure stoke cooler did about the same 3-9c cooler but could be better than that.
