NidecServo GentleTyphoon 120mm Case Fans (2150 RPM 4pin PWM)

I am an extremely biased reviewer. I was first introduced to Gentle Typhoon AP-15's many moons ago when I used to dabble in extreme overclocking and had a custom built watercooling case that was replete with Gentle Typhoons. Why? After all the research I learned that not only do they push a tremendous amount of air and have great static pressure (tremendous when used on radiators!). The part that had me sold was my rig had an excessive amount of fans and with the use of a rheobus (fan controller) I was able to manually reduce the speed on all the fans to around 50% - even with a multitude of fans it would keep a highly overclocked cpu and triple SLI gpu setup cooled - the noise was low but even what you could hear was not unpleasant to the ear! My friends and family would be amazed at knowing the computer was going full tilt and keeping cool with very low fan noise. If you see my attached pictures the black case is a recent build where I was able to re-use some of my older fans (that had been in service for going on a decade). But I didn't have enough for two builds so I purchased these and still as good as the old AP'15's. Some minor differences as in I do here an interestingly different pitch sound when just below 50% fan speed (have all fans on a fan controller although most new motherboards can control and increase and reduce the fan speeds on the 3 pin aka DC fans with ease). The 2150 RPM ar PWM fans which I made purchase of those to use on my CPU heatsink. My fiancee is floored with how silent and pleasant the wooshing sound is coming out from her PC when she is in the middle of gaming. These fans are worth the cost and in my opinion I can't stomach a PC build that doesn't include them as the centerpiece for cooling off components!

My house gets practically silent at some points of the day/night, so I like to keep my computers as quiet as possible. I used this to replace the noisy, buzzy fan in a Corsair CX430 power supply. It works great! When tested outside of the PSU before installing, the airflow was very strong, yet the sound profile is the smoothest and quietest I've heard (comparing to Noiseblocker, Noctua, Nexus, and some other quality fans). There's a slight metallic noise from the ball bearings, but it becomes inaudible once mounted inside a PC. I mounted it using rubber pins, and couldn't be happier with the results!I used the 1,150RPM model in another PSU from when Scythe used to sell these fans, and it's been running strong for about 8 years now with no signs of failure. If you want a quiet fan with strong airflow that will last a long time, and don't need LED lighting, buy these!

These fans are not for those who want a silent rig. These fans are basically industrial fans. They're beefy and they roar almost constantly. Even when they're at low RPM's. And when they crank up to half way or more, they really start to scream. You'd think your computer was about to catch on fire or something because you think they're working so hard to cool things down..Nope, that's just how they normally sound. But damn, they really like to move the air around, and that's all that matters to me. I have two set up for intake to blow cool air down onto the components, whereas I used to have two lesser quality fans blowing exhaust up and out, they just wouldn't have been powerful enough to suck enough air in to make it worthwhile. But these Typhoon fans suck in a heaping amount of cooler outside air and cooled my rig down a handful of degrees. I also took the fan from my ancient Hyper 212 CPU cooler from like 15 years ago, took the bracket off and swapped my stock rear exhaust case fan with the old 212 fan which is much more capable/powerful. And it's bringing out much more exhaust than the stock fan. So now I have healthy amounts of cool air coming in from the front, and not the top thanks to the typhoons and a def upgrade to the rear from my old Hyper 212 cpu cooler.So basically, if you don't mind loud fans that get the job done very well, then buy these. If you're looking for a silent rig, then stay as far away as possible from these fans. There are alternatives similar to these that are much quiter.

First of all, the price provides a much better value for the performance than its main competitor, the Noctua NF-A12x25. This fan is actually quieter than the Noctua equivalent whilst moving more air.I installed two of these on my 240mm AIO liquid cooler in an ITX PC. The included fans with the AIO were cheap and noisy, so I gave the Nidec GentleTyphoons a try.These fans provide better performance, with a better price. But they did cut costs to sell these fans by not including accessories and mounting hardware. However, the PWM connecter in ugly and is not sleeved in any way. Noctua does this better in the department by shipping their fans with noise isolation material and other accessories, but they cost considerably more, especially when buying them in larger quantities.Overall, I am satisfied by the performance of the fan. I just wish there were more accessories included and the PWM connector could be sleeved.
