Summary: Extremely strong air flow and very quiet. I have two of these and can not even tell they are running. I am very impressed with how well these work to cool my CPU. I use on on my heat sink and one as an exhaust fan and have found this is very effective in keeping my system running cool and performing...
Summary: Plant to buy more to see how it will help out the air flow in my Mechatron X mid tower case.
Pros: Paired it with the fan that came with my Arctic i32 co and temps have been a dream. Pushed my 6600k to 4.3 and temps even when gaming never gets above 32 degrees Celsius . Idle is @ 25 degrees Celsius.
Summary: Arctic Cooling has done it again. I liked the ability to daisy chain my fans and actually get rid of a fan controller taking up space. Sound is acceptable even at 100% compared to many. Looking for a decent case or Rad fan this one fits the bill pretty well.

Summary: Quiet and each fan comes with a pigtail for attaching another fan so I can use 1 motherboard connector to power 3 fans. I only needed 3 fans but the price for 5 was almost the same. Now I have extras for my second computer. Would buy again.
Replaced 5 80mm fans in a Supermicro SC846 4u case. Result: Slightly higher temps, but much much quieter.

Summary: I used these to replace the 80mm fans in a supermicro sc846 case. The fans that came with the case were very loud. These are much quieter. Although the airflow is less than the original, the increase in temps.is still within the operational guidelines for my CPUs and it does not sound like a jet...
