Cooler Master Silencio FP 120 PWM Case & Cooling Fan (4-Pin) - 120 mm Ultra-Quiet Fan (6.5-14 dBA), Sealed Loop Dynamic Bearing (LDB), Exclusive Silent Driver IC, Jam Sensor, MTTF 160K hrs - Black

The fan on my CoolerMaster Hyper 212 EVO died, and I bought this as a replacement. It was easy to install, and is nice and quiet. A good purchase.If anyone is hesitant to try to do this on their own, there are some YouTube videos that show how to remove the old fan, put the mounting brackets on the new fan, and put the new fan on the body of the cooler. It is a simpler process than it might appear to be. Just be sure you know where to plug the new fan into the motherboard for power.I had to take the memory out of my PC due to space considerations, to get to the fan, but overall, replacing the fan was easy to do. No need to remove the cooler from the motherboard. I just took the memory out, popped the old fan off of the cooler, put the mounting brackets on the new fan, popped the new fan onto the cooler, plugged in into the motherboard, put the memory back in, and done! I didn't time it, but the whole thing took way less than half an hour.I don't give out 5 star reviews often, but this product earned it.

Bought two to replace two front, inward-blowing fans that generated a lot of noise. Went from 70 dB with a 300 Hz peak two inches from the front of the case to 48 dB with a 200 Hz peak, and most of that is from the two CPU fans and the rear fan. The Cooler Master fans are so quiet that I removed the panel to make sure they were actually spinning. I'm very pleased.

I bought this to replace an old fan that started making a lot of noise. Took about 10 minutes to replace. Works great. Runs nearly silently.

This is a good quality fan, the operation is good but the fitting has an issue. The fan comes with 4 rubber screws and 4 metal screws and the rubber screws are very fragile, they break easily when pulled. I use this fan as a front fan in my case and tried to mount it with the provided screws. But i ended up breaking a rubber screw when i pulled on it. Cooler Master could've done better by offering more rubber screws in the package rather than just four. These same rubber screws don't seem to be available in the cooler master online store either. What i could search was third party replacement rubber screws that came in a bundle and did not look exactly like the provided rubber screws. So instead of buying those, what i did was mount the fan with three rubber screws provided in the package and for the fourth hole i had a spare metal screw (long type) and i just used that. There is no way to stick back a rubber screw if it comes apart. Rubber screws guard better against vibration than metal screws, wish they weren't as fragile to install.Now for the actual fan. The operation has been very quiet using it as a front fan in a desktop case lying a few feet in front of me. This is the newer cooler master silencio FP 120mm PWM (4 pin) fan, cooler master also has an older model of this fan which you can find in a bundle here on amazon. This one is a single fan and it seems a small improvement from the older model when it comes to operation and looks. Cooler Master description says 'Silent driver IC technology provides a smoother, less torque impulse for an ultra-low noise and minimal vibrations from the beginning to the end'. I don't have equipment to test the CFM and noise level (dbA). But from what i hear, i can say it manages to stay very quiet even when my htpc is under heavy workload, it might be a little better than the older model PWM fan from cooler master i used a few years back. Looks wise, the blades look high quality when you look at them up close. This looks like a premium quality case fan. Also, note that this is a sleeve bearing fan and won't be a good choice if you want horizontal mounting.Overall, i recommend the fan but be very careful when installing the rubber screws and the force you apply on them.

I like the name. Didn't need RGB, just a good bargain. Been buying Cooler Master for years. The name should have a Lucha Libre mask on the hub.

I use this in the rafters of my solar powered chicken coop and it does a great job of keeping the hot air hot. It is whisper quite.

This was easy to install and came with all the hardware needed. However, these fans are NOT perfectly silent, but the noise/fan level has been reduced by at least 50%. To actually reduce all noise from any large desktop system, you really need to place the computer's case inside its own enclosure; ie, a closet, of which I do not have. Or you can build a custom closet/enclosure below a work table. Or invest in an alternate computer system that does not have any noise at all, of which I'll be doing in the future.

Very quiet and reasonably priced。
