Review on 🧊 ARCTIC F14 Silent - Ultra-Quiet 140mm Case Fan, Extra Quiet Motor, for Computers, Nearly Inaudible, Fan Speed: 800 RPM - Black/White by David Sidman

These fans are the best I've tried. I recently bought an Antec P100 Silent case and wanted to replace the stock 120mm fan with two 140mm fans in the front. I love how these fans push their limits. When my computer is idle, they stop. If I overclock and run the CPU at 100% they can keep up and maintain a safe temperature. I even like that they are gray and don't have bright LEDs. They sit behind the front grill behind the door and the blades are good to see if I want to. And they are built to last. And I like to leave my computer on, so I find it more energy efficient when it's off. Also, I connected them together, so it was nice. Finally, I like the price, which is really good for a PWM fan without LEDs. A few caveats. My Asus motherboard has an optimization mode setting that creates a fan curve. Unlike my other fans, this doesn't give a good control curve. So I just set it to PWM control with a standard or soft curve setting. I almost sent it back because the fan was too thick for my case screws. It's 27mm thick and my Asus screws are 25mm long. After some research and a wasted trip to a computer store, I found out that they are also called heatsink screws. And that I needed #6-32 1 1/4" screws, which are available in packet form at your local hardware store for just over $1.00. Installed the fans with no problems. So glad I didn't give up! I am happy with this purchase these are quality fans at a fraction of the price.
