5 Pack, 120mm PWM Case Fans – 4-Pin Silent PC Fans, 1500 RPM High Airflow 67CFM, Low-Noise 28 dBA, Quiet Stealth Mode, Anti-Shock Pads, PWM Sharing w/ 1-to-3 Splitter Cable, Hurricane Series

I was looking for fans to add into my recently upgraded PC that was housing higher end, higher temperature parts. My components were running hotter than I wanted and I think my original case fan was starting to deteriorate. I replaced my singular top exhaust fan with 3 of these and it produced a noticeable difference. They were doing their job, and I have yet to see any cons.Pros:Sufficient speed- I did not measure the velocity of air, but it feels normal. Blades spin so fast its difficult to see it move.Quiet- I have not noticed any noise from any of my fans. All I can hear is coil whine in my GPU, which is fine by meConnectors- I like the ability to chain together multiple fans together. This makes it possible to connect multiple fans to one fan pin on the motherboard.I like these fans. They are the most standard size of computer fans, they are cheap and easy to use. For future PC builds, I will continue to use these fans as long as they reliably work.

they're quiet to keep my PC full and it didn't cost a fortune.

Standard 120 mm case fans (set of 5), each with a 4-pin female end (No Molex), and a separate bag with 4 screws (set of 5). Also included are two 3-way fan splitters. Each splitter has a 4-pin female end that can attach to a 4-pin male chassis MOBO fan header. The splitter is serially arranged with two 3-pin male and one 4-pin male. Each fan has 9 blades. They are black (No RGB), which I was aware of. There are no directional arrows on the fan enclosure, which are not necessary. For the first time novice, there is plenty of info on the web about case fans placement (direction of flow/rotation/intake/exhaust). They are relatively quiet, but not ultra quiet or silent. The listed ratings of 67CFM, 1500RPM and 27.5dB may be meaningful for the physics inclined techie out there, though personally I go by the 2 senses of seeing and hearing, as well as functional performance. I am sure there are much better-quality fans, but these are good enough for me, considering the price paid. Time will tell. Recommend and would purchase again. Thank you.

Tested Power; 0.21A, 2.49W @ 12.0 Vdc. Speed and Sound typical of around 1500 RPM with substantial Airflow. Fan is possibly performing better than specified with more air. Quality build, complete with connector cables and mounting screws.. Will provide future update with measured CFM, Velocity and RPM.

I got them they run good and most if them are completely quiet except one the bearings bent or something but I imagine every sets not like this keeping my 4060 rtx setup nice and cool though so there not that bad

These are very quiet and have good air flow. The cable length is good and they are very easy to install. Screws are included.

Pushes a lot more air than my old set of fans that I thought were soo great😅. I'm actually about to buy another set because I didn't order these for the PC I ended up putting them in, I only used them in my gaming pc because I noticed my gpu temps while playing Fallout 4 and Falout 76 were at a steady 85°C with the occasional 86°C, although thats technically still fine, i didnt like seeing that.After installing, the fans dropped my temps while gaming about 5-10 degrees (F4 and F76 temps cap out at 80°C). During idle I went from 40-45°C down to 30-35°C. (Im using 4 of the 5 at 100% power bc they're plugged straight in PSU via SATA power)NOTE: GPU thermal paste was also redone when i swapped fans out. Also, running 4 at 100% is a bit louder than the previous fans running at 100% as i believe these spin at a higher RPM and my old ones, but its nothing that good mic settings/noise suppression can't fix. I don't even notice it until I take my headset off

This should be a four star review. The product was delivered very quickly, it was as advertised, and the couple of hours that two of these have been spinning have been uneventful. Why it's three is the delivery.Four of five had no issues, but the box was crinkled on one side and one of the fans had the housing/shroud around the fan cracked, with the segment of resin rattling around at the bottom of the packaging. Obviously the thing has some sort of preloading, because the fan blade clipped the shroud in operation due to this missing piece. I'm getting adhesive and will try to fix the problem...but these are cheap enough that I'm not even contacting the manufacturer to complain. It was likely mishandled somewhere...which nobody will ever admit to. Otherwise, a solid purchase that I'd recommend if the specifications are reasonable to you (flow rate, amperage, etc...).
