3 out of 5 eggsWorked for a while

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 period.

Other Thoughts: Was nice when it worked but expected more longevity. Was in a rig that ran 24/7 at stock speeds.

1 out of 5 eggsDid not work as intended

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 antec support about it and they basically said" its your fault it doesn't work." and left me hanging..

Cons: if you get a defective unit. you basically threw away your money,.

1 out of 5 eggsSo bad

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.

Other Thoughts: 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.

5 out of 5 eggsExcellent cooling

Pros: This cooler comes with software that tells you the temp of the coolant circulating through this device. According to that software the coolant has never gone over 44 C. Even after running at 96-100% CPU utilization for over 5 hours.

Cons: The original cooler I bought went bad after about 11 months. Antec was quick to approve an RMA and down time was less than a week.

Other Thoughts: Although my original cooler went bad after 11 months it worked great up to that point. Given that Antec was so quick in sending me a replacement after I sent mine to them I decided to not take an egg away. The replacement cooler has been working for sometime now and works every bit as well as the original.

1 out of 5 eggsKuhler 920 failure

Pros: It worked very well for almost a year.

Cons: It failed, starting almost a year after I installed it. I found liquid around one of the fans, indicating that the radiator leaked.

Other Thoughts: When the 920 began failing CPU idle temperatures rose from the original 32C to about 47C (Intel Desk Top Utility).

When the Win 7 Defragmenter kicked in the CPU case temperature soared to 67C - the maximum. Photoshop and other programs would also overheat the CPU.

I replaced it with an Intel TS13X and CPU idle case temperature is back down to 32C.

Running the Intel Processor Diagnostic Tool with a 20 minute maximum load CPU stress test raised the internal temperature to only 47C - well below the internal maximum of 96C!

1 out of 5 eggsDon't buy this

Pros: Price not so high

Cons: First of all this thing is made cheap, First you have to turn the fourth screw on a plastis socket, i sould be on a metal socket because if you turn this to tight you can break it.

-Next i use it in normal operation and the cpu it's still around 30-40 degree and in gaming mode it'S up to 60.
My computor still overheating, i reinstalle it twice for be sure it's was correctly install and this is not getting better.

Other Thoughts: This is not the first system i install, i did the installation correctly it's sad it's not working better i will probably have to change it.

5 out of 5 eggsVery pleased

Pros: This is probably the best cooler I've ever had. I can run an AMD FX octacore at 4.6 an I never see a temp above 40 Celsius while at highest load. It looks really good in my tower an the ability to the light color was nifty. The software that was included was quickly installed an working flawlessly.

Cons: The only con I have is the bracket was a bit rough to attach but with a second person helping it was quickly installed.

Other Thoughts: This is a great cooler but I definitely recommend having some help on the installation

1 out of 5 eggsCooler doesn't last long

Pros: n/a

Cons: It lasted maybe 6 months of game play and now gets very hot to the touch and sounds like it's about to take off. Very loud.

It's used through out my work day for helping customers that are on windows computers and having issues/troubleshooting a program that I help troubleshoot at my job. Then after work I get on for about 2-3 hours for game play. (MinCraft, WOW, SImCIty and the Sims)....For about 6 months everything was fine. Now I can't even play SimCity for more than 15 mins without the fans running like crazy and the cpu and tubs getting very hot and not cooling down.

Other Thoughts: I bought some thermal gel and two new fans for my tower in hopes this will help...but will update if end up changing out the cooler instead. I think it might come to changing the cooler since my hubby has one model down and plays WOW almost all day...without any issues.
