Scythe GentleTyphoon D1225C12B5AP-15 120mm Case cooler

Pros: Quiet fan, doesn't vibrate, turns VERY easily.

Cons: This is listed under the specs, but this only puts out 58.3 CFM.

Overall Review: If you don't need a superpowered fan, get this. This wasn't enough for me, so I just went with something that put out about 130 CFM.

Pros: This thing just FEELS high quality. It's heavy, the blades spin extremely smoothly with almost no resistance, and it doesn't vibrate the slighest in any position. It's nearly silent at full speed. Absolutely no need to get a lower speed fan. Moves a good amount of air, but, most importantly, moves that air through even a dense heatsink. Great static pressure. Well, well worth the money.

Cons: It's heavy. That goes along with the quality, but this is the heaviest 120mm fan I've held.

Overall Review: As case fans, these don't move a tremendous amount of air. They shine as heatsink fans because their static pressure allows them to maintain the majority of their flow even through a dense array of fins.

Pros: I got several of these for an application were I wanted considerable airflow with the lowest possible noise and vibration. They are the best engineered fans I have ever seen. The impeller has all the complex geometry of an aircraft propeller, with precisely contoured (not "cut") leading edges, and variable pitch and width along each blade. My monitor vibrates as much as these fans do. At 66% (maybe 40cf/min) they are dead silent at 3 ft. At 100% (60cf/min) they make a very quiet and pleasent "thrum" that best resembles the sound of an air force transport plane about 3 miles away.

Cons: At $18 each plus shipping I am dividing them among the children when I am called to heaven.

Overall Review: These fans remind me of a bastardized version of the 3M motto: They don't push more air than some other fans, they just push the air, better.

Pros: Simply the best case cooling fan that I have tried. Very quiet! Moves a good amount of air. I have tried alot of fans, ALOT, and this fan is incredible. Nearly inaudible and moves a very good amount of air. I will not sacrifice on air movement as I rely on a case fan to cool my Thermalright CPU IFX cooler that is 5 inches away from the fan.

Cons: I just wish I had nothing but these fans in all 4 of my computers - but that would mean replacing nearly 20 fans. Just too bad that I did not stumble across these sooner

Overall Review: If you want the best fan - this is the one to get

Pros: These are really great fans for forcing air through radiators and other obstructions. They don't have the highest CFM, but they do not lose their CFM as drastically as other fans when a blockage is introduced.

Cons: They make kind of a low pitched whine that isn't exactly unpleasant, it's just different. Could be because I do not have any rubber cushions between the case and the fans.

Overall Review: Got 2 in a push/pull configuration on my corsair H50 and it dropped my load temps 5-6C over the stock corsair fan. It's cold in the room right now so with higher voltages and more ambient temperature the difference in temps will be more drastic for sure. GET THESE TO GO ON ANY RADIATOR!

Pros: These keep my CPU cool. With a zalman fanmate 2, I can crank them up for heavy overclocking, and dial them back when I want quiet. They're the quietest fans I've used.

Cons: not absolutely 100% quiet. A bit pricey.

Overall Review: Not PWM fans, so you won't be controlling the speeds through a 4-pin PWM mobo fan header. There's a plethora of fan controller solutions. If you want quiet all the time, never need a hurricane, and don't want to mess with a fan controller, get the D1225C12B3AP-13 1150 RPM version instead, plug it in, and forget it.

Pros: WOW. This fan moves a lot of air. - very quiet for the amount of air it moves - the noise it makes is not annoying like other fans, it has a rather pleasant pitch to it. - fan spins with no resistance at all, seems like if it was in a vacuum it would spin forever.

Cons: - not completely silent - GIANT dead spot in the middle - cables are a bit short (see other thoughts)

Overall Review: dropped my load temp 7 degrees. Great fans for the H50 cooler (i have 2 of the fans in push pull). The absolutely giant dead spot in the middle is definitely reducing this fans potential when mounted on a radiator. A shroud should fix this problem easily, so no egg deduction. The cables it comes with are a bit short, if i wanted to mount the fans with shrouds i would run into a problem because one of them would have to be outside the case. Still no egg deduction as its working perfectly right now with no shrouds. Great fan overall, completely worth the $16 + shipping. If you have an H50 buy two of these fans, you wont regret it

Pros: Amazingly silent. I went from one of those old Vantec Tornados at 4000+ RPM to *two* of these. My old PC used to sound like a jet engine. The new one hardly makes any noise at all.

Cons: Not really a con, but all the GentleTyphoons are rated in cubic meters per hour rather than cubic feet per minute. I had to do my math, but since you read this review, you don't! 1 CFM is approximately 1.7 m3/hr.

Overall Review: The bearings on these guys are awesome. When you power off it takes quite a while for them to stop. They just scream "quality". Or they would, if they weren't so quiet.
