Kingwin 80mm Silent Fan – Quiet PC Cooling Fan for Computer Cases, CPU Coolers, Mining Rigs – Long Life Bearing, Maximum Airflow, Low Noise, 80mm Computer Case Fan – Black

I have a loser acer nitro suckface edition desktop that I'm planning on giving my wife. It never had much ventilation as none of them do. But it had space for an 80mm fan on the back. When I unfortunately had to use this as my main rig, it was loud, the cpu and gpu fans would always sound like a jet engine, even while just doing some mild surfing or watching a movie. But as things have changed, I am back to being able to make builds and upgrade old ones, and this was part of that upgrade on this system. Cleaned it out, added the fan, and it is so quiet now! This is a fantastic upgrade for it.

Exactly as advertised

Fan was sized as described, it works.

WORKED AS I WANTED FOR MY PC

2 stars for the description. The package says 1000 RPM. The description says 1700 Max. I don't know if the "Max" should make a difference, but it is a slow, gentle fan. Good for my use, but I would be upset if I wanted more airflow. Maybe, if the computer gets hot, it will speed up. I don't overclock or push the performance, so I will probably never know.

These fans are basically silent and a good price for a 120mm. Have two in my case, can't even tell they're on when running.

It doesn't have as much air movement as I had hoped. I don't have a way to tell if the company as advertised is accurate but the box they come in states they only spin at 1k rpm not 1700rpm . I thought that would be enough but it lacks the blowing force. It is built good and quiet for a 140mm fan.

Black PC exhaust fan. Not a thin fan, but standard thickness, but works great right out of the box, once connected to the PC unit. Multi-plug functionality. Relatively quiet. It would be nice to see them in a pack of 2, 3 or 4. Otherwise the only drawback is have to buy one at a time.
