GELID Solutions FN-PX09-20 92mm Case cooling

Pros: Quiet/inaudible (depending on speed) Moderately priced 5 year warranty

Cons: I installed two of these as intake fans in an Antec Solo case. The included rubber grommets are too big to fit behind the intake air filter, so I attached the fans with machine screws (not included). No installation manual in the box or on the manufacturer's web site. The FAQ on the web site shows how to install the rubber grommets.

Overall Review: These fans have a four pin connector which allows the motherboard to control the fan speed. If you plug these into a three pin connector, the fans will run at maximum speed, which is specified to be 2000 RPM but is actually about 2120 RPM. At that speed, the fans move a lot of air but are moderately noisy. The noise is is fairly tonal. If you connect them to a four pin connector on your motherboard, then the speed will depend on your motherboard. My motherboard runs these at 1300 to 1350 RPM, and I can't hear them at all. If your motherboard doesn't have the ability to control fan speed, you may want one of the other variants of this fan (N82E16835426004 or N82E16835426006).

Pros: Very Quiet compared to my old fan Insainly easy to assemble. (i child could assemble it in less than 30 seconds)

Cons: its really just Quiet due to the low RPM. The fans air flow is nothing in compaired to my old fan i have it on full power and the air flow isn't that great Shipping took 5 days not 3

Overall Review: its a good deal for $14. i was going to put it on my CPU but dont know if it will cut it.

Pros: Very quiet operation. Fit perfectly inside plastic housing that old fan was in. Went into a Dell Dimension 4600 case, Intel DP55WB motherboard. Four pin connector allows fan to be pulse width modulated, increase/decrease speed as needed automatically. Wiring harness has protective sleeve.

Cons: None.

Overall Review: Having a PWM capable board is nice because the fan won't run on high all the time.

Pros: It's a PWM fan that fits with the Scythe Ninja Mini Rev B. heat sink.

Cons: Annoying "buzz" at maximum speed. At 50%, I can still hear the slight "buzz" from the fan. Cooling performance is decent.

Pros: Quiet, quality build

Cons: Can't see any

Overall Review: Bought it to replace stock fan in MASSCOOL 8WA741 CPU heatsink which started to make some noise.

Pros: I love these fans. Their stylish (neutral) black/white design matches virtually any build. They have very high static pressure for a "silent" fan, which makes them great intakes through fan filters. PWM controls makes it easy to adjust their speed directly from your mobo. No "PWM ticking" or motor noise on 5v. And, they come with soft silicone mounts to eliminate case vibration. The 3 year warranty is just icing on the cake (and out of the 20 or so various Gelid fans I've owned/installed I've never had one die on me).

Cons: The soft mounts aren't particularly intuitive, and the fans don't ship with instructions on how to install them. Gelid does have a guide on their website though, so no points off there. They can be a bit of a hassle at first, but a toothpick or a small phillips head screwdriver can help guide them into place.

Overall Review: Gelid has been my go to brand for quiet computing for years now and they continue to impress. Although the mounts may be a hassle, they're absolutely worth installing. I've tried both screws and the mounts and they make the difference between these fans being "quiet" and virtually inaudible.

Pros: low noise, inexpensive

Cons: audible pwm ticking, no included accessories, only 50,000 mttf

Overall Review: This fan was used in a pc that stays on 24/7, so it's life span seemed short. I have since switched to a fan costs twice as much, but has three times the life expectancy, includes low noise adapters and mounting options, and does NOT have the PWM ticking. Much more for the money.

Pros: Using these as exhaust fans on my Dell 4700 and 4600 Desktops sitting outside of the back of case by slot card openings for sucking out heat. Living in the desert where the computer room temps range from 82F to 92F. I keep the case doors open and got Radio Shack AC cooling fans blowing into the case from the side. Everything is cool. These are very quiet for me running at full blast, and makes much less noise than the Cooler Master Blast Master 92.

Cons: nada

Overall Review: Sadly, it does not cut it for whole house cooling here in the Chihuahuan Desert.
