ARCTIC F8 Pro PWM Fluid Dynamic Bearing Case Fan, 80mm PWM Speed Control, 33CFM at 22dBA

Pros: Just replaced a six yer old standard Lian Li top exhaust fan and the noise is down significantly and the air exhausting out the top of the case is more definitely at least as much if not more at reduced fan speed of around 1600rpm, and at 2000rpm still quieter than stock Lian Li but much higher air pressure.

Have these fans (92mm version) running on my CPU cooler for 6+ years and still going strong

Cons: None

Pros: PWM and quiet. It works, as advertised. Will buy again when the need arises. They work great blowing across the mammoth heatsink of the Asus C60M1-i. I don't ever expect any heat issues.

Cons: see Other thoughts

Other Thoughts: They are just a bit thicker than most fans. In 99.99% of the cases (yes, pun intended) this should not matter. However, I am putting these in an Antec ISK case, which is small, so it does matter. I will be doing some case modding to remedy the issue.

Pros: The idea is great, the blades and motor are dead silent(not the whole unit unfortunately.) Puts out a good amount of air. Its design starts this review well,

Cons: but the execution erases any practical use of this product.I was excited about the "rubber fan holder" when I saw it, but that's where it all falls apart for me. The rubber suspension holds the entire weight of the motor, blades and cage. This, combined with the flexibility of the mounts, lets the fan blades droop low enough to touch the enclosure mounted to the case or CPU and rattle or click against it constantly. The only application these fans would be suitable for would be as a top vent fan, but I have a 120mm fan for that already.

Other Thoughts: If the rubber suspension connecting the cage to the enclosure were a bit stiffer, these fans would be perfect. Another possibility would be higher clearance on the enclosure.

Pros: Nice looking

Cons: I ordered two of these. One of them made a clicking sound straight out of the box. The other one took a couple weeks but it, too, clicked. The problem is that these fans don't sit properly in my case, a Silverstone GD05B. When you put the fans into the rear of the case, the box around the fans is squeezed and then the fan blades hit the box, making a clicking sound and often causing the blades to stop occassionally.

Pros: While it's fun and educational to test numerous fan vendor concepts, I have recently emptied my numerous chassis of any other brand fan because the PST patented PWM sharing technology from Arctic Cooling simply works effectively and quietly, offering a high quality air-cooling solution with a Plug and Run, unified, integrated, demand load RPM regulation feature that control all of the respective AC fans which includes up to five (5) case/system, memory, and CPU coolers. I found that many of the product specification listings here for the AC Case fan products are incorrect at the time of this review.

F9 : 43 CFM / 73.1 m3/h
F12 : 74 CFM / 125.7 m3/h
F14 : 77.3 CFM / 131.4 m3

Cons: None

Other Thoughts: I found that when used across various yearly revisions of motherboards, using this brand eliminated the surprises that come with one motherboard versus another having different fan header pin types, (3) versus (4-pin) and also numbers of headers. I have them installed in both intake and exhaust configurations and as the primary for several water-cooler radiator cooling solutions.

Pros: Spins round and round and moves air quietly.

Cons: Wasn't free and didn't install itself?? No real cons.

Pros: Very quite even at full speed. Open rear allows broader / less directional air pickup for more even extraction. Good air flow for such a quite fan.

Cons: This fan can only be mounted from one side and fan rotation direction is not reversible (it blows air out from it's mounting side). In most case configurations, it will not be suitable for use as a "front" case fan. It might work as a side exhaust fan to augment a negative pressure configuration but its primary purpose appears to be as a basic rear case exhaust fan. An 80 mm fan is a bit small for this but it can work if it gives you sufficient airflow. Keep in mind that most of the smaller "quite" fans are quite simply because they run slower and move a lower volume of air.

Other Thoughts: This is a good technology choice that will help future proof your computer case. I expect all future motherboards will support 4-wire PWM case fans. I have tested this fan with a 3-wire motherboard connector and it works just fine - at full speed of course. The ability to daisy chain off the PWM CPU fan is trick but keep in mind that case fans service more than just the heat generated by the CPU. It might be possible to have a memory intensive application running that does not use a lot of CPU. In that case, if a chained case fan was running slow due to low CPU utilization (i.e. cool operation), a condition might arise whereby the memory (esp. if overclocked) would not receive adequate airflow.

There's a lot to think about when spec'ing case fans. For best results, do some homework first. Remember, the CPU fan's output is not normally counted toward total input/output ventilation. It just removes heat from the CPU which must then be extracted by the case fans or power supply

Pros: got two of these as exhaust fans in a 4U rackmount case. even with the lid off, you cant hardly hear these fans until you put your ear up next to them. insanely quiet. i mean i really had to take the case lid off and make sure they were running they're that quiet. perfect for audio machines.

Cons: short leads. consider purchasing extensions if you're not sure about the fit.

Other Thoughts: bought two of these and two of the 120mm fans for this case - the 120mm are junk and sound like a dentist drill in the case. these, however, are the bees knees, and fit the bill exactly as I needed, which was for a audio workstation.

Pros: Silent.
PWM Sharing.
Rubber suspension system for no vibration/noise.
HydroDynamic Bearing; silent and long life.
Black/White goes with just about anything.

Cons: Thicker than average 80mm fans because of rubber suspension system.
Wouldn't fit where I intended it in MicroATX desktop case; Silverstone Sugo.
Still used it in a different location.

Other Thoughts: Hard to find better all around performing fans than AC. Great CFM, quiet, long lasting...great buy.

Pros: "GREAT" choice for a super quiet fan . . .

Cons: Absolutly none.
