KWI Technology Inc./Kingwin Kingwin 140mm Silent Fan for Computer Cases, Mining Rig, CPU Coolers

Rebuilt my computer that runs hotter core. My computer is surrounded by low air circulation enclosure. Added 2 fans that pull air in across CPU fan and out a 3rd factor fan. Motherboard controls the fan speed. Cools sufficiently for my use. Fits both next to each other in the tower. Very quiet as advertised. 4 includes screws are not self tapping, so they need a "head start" on the bench to tap the plastic into shape. Installed upside-down at first then installed right-side up. Pretty easy. Working just fine!

I had to replace a noisy fan in my computer. I didn't need a fancy fan, just a simple one. This fan met my needs in terms of price and usability. It is quiet and does its job.

Good, quiet fans. Lightweight, smooth turning, 100% compatible electrical connections with modern motherboards. Recognized right away by the BIOS.

For an 80mm fan, this is acceptably quiet, particularly compared to the stock fan it's replacing in my ancient Antec case. But it is not silent. I've installed 3 of them in my system and they can clearly be heard at boot. Under high CPU load, they drown out my Cooler Master Hyper 212 EVO V2 CPU cooler which is barely audible. However, one can't expect it to perform like a 120mm fan. They move the air well enough to keep the system cool. As to quality control, one of them did not come with mounting screws. Perhaps there are different manufacture versions but all of mine DO have arrows embossed on the body to show air flow direction. Perhaps ones from beQuiet or Noctura would be truly silent but at this price, it's a reasonable trade-off. Time will tell whether they last but for now, I'm satisfied.

One of the fans in my prebuilt pc cracked after 5 years of owning it. I had my eyes on this fan, gave it a shot, and it works better than my other fans! It doesn’t have the pretty lights that my other fans do, but at this point I’m looking for performance and this exceeds the mark! Super quiet as well.
