Cryorig 140mm PWM 700-1300U/min Computer Fan, 140mm Length, Desktop, Server Compatible

Pleasantly surprised, this fan pushes a lot of air. It's not completely silent about it, and only 3-pin, but it comes with some clever mounts which absorb vibration.

Mounts on 120mm bolt patern

I ordered these fans to help exhaust the hot air out of the top of my Case. I recently did a rebuild of my PC in a new case and the clearance between one of my radiators and the top of the case is pretty slim. A normal sized fan was not going to fit. Ordered these and they were even thinner than I thought they would be. They run quiet and do move quite a bit of air! Super happy with them so far. I normally dont care about the packaging of things too much as long as they arrive unbroken however the quality and care of the packaging for these is top notch. I frequently buy Noctua fans and love those dearly but these seem to be on par as far as quality is concerned. They dont have any of the accessories that the Noctua's come with but i'd like to think that means i'm buying more fan and less extra stuff.

Good: Slim, compact form with shock absorbers for minimal space builds. Comes with the option of either rubber or metal screws, and a molex connecter. When connected to a motherboard, it works pretty well. Bad: The design of a 140mm fan with 120mm screws is puzzling. That means that if you want to hook up two of these to two adjacent exhaust/intake slots, they won't work because of a lack of room (if the slots are two 120mm). However, for a single fan exhaust, it could be serviceable. In terms of noise, if you attach this to a power supply unit without any means of controlling it, it will be fairly loud. That is usual for slim fans. Verdict: A good fan for a mATX or, better, ITX computer build. Be sure you have your measurements in order before you buy, or else you might have a fitting issue.

The good: slim and it works. The bad: mine was noisy. Soft swish-swish sound from the bearing/motor area even when spun by hand. At minimal RPM, made a pulsating noise that got louder and more annoying with RPM. To be honest, it wasn't that noticeable while gaming. In addition, the screw holes are larger than necessary, and the screws can't be fully tightened, as they just keep turning. I will keep this as a spare, but I just replaced this fan with a Prolima Ultra Sleek Vortex 14, which is the same size, nearly silent, and has correctly sized holes.

After 1 week of usage it started making rattling sound. It uses low quality sleeve bearing, and this issue is common to this model. Please google for: 'cryorig rattling' and see for yourself. Cryorig has ignored my queries to send me a replacement. Amazon agreed to refund me, but only after I send it back. Which is not suitable for me because it takes 1 hour to assemble and them dissasemble because I'm using mITX build. I ended up not returning it (so I lost money on it), and buying Noctua fan instead. I do not recommend it.

Very nice. I mounted them on my Corsair h110i radiator, which has 140mm bolt holes while this fan's holes are at 120mm. I knew this when purchasing, but could not, for the life of me, find slim 140mm fans with 140mm bolt holes. They all had 120mm spacing. I solved this by getting some plexi-glass from home depot and making little blocks for each corner with two holes, one for the 140mm screw on the radiator and one at 120 for the fans. This fan comes with some really nice rubber plugs that function in place of screws. I would have loved to use them but I messed up my initial design and ruined the rubber plugs trying to pull them out. :(

Pros: - Good airflow when it worked - Relatively quiet. But it's no Corsair AF120 (I can't even hear those). Cons: - 120 mm fan mounting holes NOT 140 mm (as noted by others) - Fan popped out of the motor after about 2-3 weeks. Probably from me pushing on the center of the fan guard due to the fan blades "grinding" against to the case shroud (Antec 300 top 140mm mount). It would be nice if the fan blades had more 'countersink' into the housing to prevent this.
