I bought this fan to replace an older Antec fan that became noisy. Replacing this fan was not easy for me because this fan does not come with silicone grommets. My original fan was installed that way, and it's in an Antec case. Zalman includes the grommets even with their $8 fans. Reusing the old grommets was not easy because they are not designed for that. The fan came with mounting screws, but they did not fit the holes in my case where the grommets were.
As for the fan itself, it's quiet and works well. The temperature causes the fan's speed to vary, and the fan seems to be doing exactly what it's supposed to do. The package shows a chart with examples of speed, air flow, noise, etc. at various temperatures. When I installed it, my case had been open. The fan started out at about 1100 RPM, which would be appropriate for a temperature of somewhere between 25 and 30 degrees C. I used software to monitor the fan speed as well as temperatures such as my motherboard's. I can't tell the exact temperature of the air flowing, but when the motherboard got to 35 C, the fan was hovering between 1310-1312. The package says it should be at 1310 when the air is 35 C. The air flow is 46 CFM at that speed.
My computer has four HDDs with an internal Zalman fan blowing air away from them, toward the back of the case. I'm using this Antec as the rear exhaust fan, and the only case exhaust fan, unless you count the power supply fan. Air passes through my HDDs, out an internal fan, past the motherboard area, and out the back. I tried some tasks with heavier HDD activity, and the fan sped up, but not by a lot. At the same time, my motherboard temperature dropped.
The fan hasn't needed to go past 1350 so far, despite two older HDDs that are less efficient than current ones. So there's plenty of air flow without speeding up enough to be noisy.
Somebody commented that the fan seems to be staying around the same speed. It should. If it tries to keep the air at a constant temperature, it would speed up to do so. But that would keep the temperature where it should be, so the fan should slow down. It's normal to see the speed increase by a few RPM, drop by a few RPM, and continue doing so within a relatively limited range. The range may increase as necessary, but with a fan that can replace all the air in your computer in about a second when at top speed, it should have no need to ever get there.

excellent air mover for this size. Used for cooling entertainment center electronic components, including 46" Sony Bravia TV, Yamaha YSP4000 surround sound bar, lighting, and dvd player.
I had to also purchase an adapter to make the unit run on 120V ac power (regular outlet) but it works as described. There are 2 negatives to consider if purchasing for AV equipment:
1) The humming of the fan blades is loud when listening to the TV at any average volume level. Though I searched for and found only this unit is quieter than most - wow, what do the other fans sound like?!
2) The temperature gage is useless since the unit is made to turn on around 70 degrees. It didn't occur to me until after I installed it that I keep the room temperature anywhere from 70-74F in the winter, and 78-82F in the summer!

Do not buy this fan. That's the best advice I can give you.
- It's noisy and the speed cannot be changed
- The screws supplied do not 'in any way' fit
- Onboard sensor connector does not work.
I used this for 24 hours before the noise drove me to disconnect it.

I had the fan in place, the bios read its speed correctly, yet it never changed its speed. Its normal speed was so low that I couldn't even tell which way the air was flowing from it. I turned the fan around and it created the same airflow out the back of the computer. If you have a duo core processor, don't get this piece of sh**. An overclocked duo core @ 3.7ghz couldn't even get the fan to increase its speed. Avoid this fan like the plague

I bought this fan for my heatsink (Thermalright Ultra 120 Extreme). I hear a little noise coming from my case, but I know that some of that noise is due to the one 80mm fan that's mounted to the top of the case. For this fan, I'd most likely have to open up the case and listen to find out if its contributing to whatever, little noise I hear (could be the sound of the air going through the fins of the heatsink). Either way, my PC remains rather quiet in a room that is pretty much dead silent most of the time.
