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...

Keeps the meltdown away

Jeffrey Q., Newegg
6 September 2015
  • Summary: After I melted down an AMD FX-8350 CPU with my 24x7number-crunching (exceeding 90°C), I got this for a replacement FX-8230. I've been running it for 14 months with 8 simultaneous crunchers running at 75-80% CPU use, and temp stays in the mid-40s.
  • Pros: Flawless cooling 3-year warranty
  • Cons: Somewhat intimidating assembly for a first-time liquid cooler user

Zachary K., Newegg

  • Pros: cooled the PC "ok" but usb header doesnt work. so you cant control the fans so its super loud. i have been using it on my secondary pc for 3 years. pump will occasionally slow down. i might have a defective unit, but it still begs the question. why buy this over the corsair options? I contacted a...

Keeping things cool! It's TOO easy!

Benjmain H., Newegg
2 January 2015
  • Summary: This product (or similar) is a MUST buy when building a PC
  • Pros: Keeps my CPU cooled when I'm boosting OR at regular temps! Allows for better airflow to the rest of the other components by not have a clunky fan blocking everything
  • Cons: Not the easiest to install. Make sure you watch a video and read the instructions. Maybe practice what you need to do before applying the thermal paste and giving it a go

So bad

Arvin K., Newegg
31 August 2014
  • Summary: Don't buy it, USB connection us 50/50 to work for most people judging by the problems I have found on google. Just search "Antec 920 issues" and you will see.
  • Pros: It turns on
  • Cons: No control over RPM - I never got the USB connection to work or recognize. I research so many websites for solutions and none worked. Really unhappy with this product.

Quiet and Attractive

PCbuilder, Staples
8 July 2014
  • Excerpt: This fan runs silently in the bottom of my PC case and casts a blue hue over the interior of the case giving it an attractive glow at night when the lights in the room are off. Very satisfied with this fan.
