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

Great cooling and low nois

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!

used these to go along with my morpheus ii core edition cooler for my vega 64. I simply couldn't be more thrilled. both of these fans have ZERO issue pushing large amount of air through the heatsink and down to the pcb / vrm's. originally I was using two arctic f12's for temporary until I received these fans. a simple fan swap dropped my core from 57c down to 49c, hbm to 51c from 69c, and hotspot from 88c to 71c! the f12's are fantastic budget fans but the typhoon's are simply outstanding and worth the higher price tag. at max rpm of 2150, if I put the fan on one end of my desk, not only can I feel the air flow on the other side of my desk (47inch width) but also the pressure. these fans put out a serious amount of static pressure.they are a bit noisier than most fluid dynamic based fans. like noctua or fluid bearing fans from other popular manufactures. but double ball bearing fans are simply reliable and can take high levels of heat. unless I put my head near them I can't here them over my case fans. above all, they're no where near jet engine status or delta's. compared to noctua new nf-a12x25 fans, the 2150 variant does offer slightly more static pressure and cfm. the noctua will be more quieter though. I do own a nf-a12x25 that I use on my heatsink but chose to go with typhoons on my morpheus because since I was getting two fans, these are cheaper and proven. the noctua really are simply an evolution off of these and all you're really getting for slightly more money is a slightly more quiet motor. I couldn't justify the higher premium for the nf-a12's if I had gotten two.

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.
