Loud, but does the job well
This fan moves a lot of air, and for this reason is noisy. It works very well.

Quieter than the 3A version
Bought a used Isilon storage server and the fans that were installed plugged into a daughter board. This caused them to be on 100% power constantly which, for a server room wouldn't be a big issue but too loud for my living room.These were a great replacement and fit perfectly, plus was able to plug into the motherboard to allow fan control from the bios. Perfect.

Not really a PC fan
Despite being typical PC and server sizes, these have different 4 pin connectors on them than normal PC fan headers use. The wires match up and you can carefully put the fan connector on to the header but it does not seat securely and isnt really meant go connect that way.The noise rating advertised is also misleading. It says Speed: RPM 5500, Noise: 47dba. This may be technically true, but it is 47db noise volume at the lowest RPM rating, not at 5500. So these are actually quite loud for their low speed and airflow. These also have a high pitched noise, one that is more annoying in tone than many other fans. I bought them to replace my existing server fans and they are maybe 3db quieter, but the higher pitched sound makes them seem worse to use.

Strap them to a passive cooler
These bad boys will convert a passive air cooler to a top notch active cooler. I have an old Dell T410 motherboard with dual CPUs and these fans keep the chips below 30 C at idle. I do not use the server case. I built my own so fit will need to be considered. The PMW pin works flawlessly with the Dell BIOS.

You buy these for the air throughput. Not the noise levels
I got these to suck some air out from hpc gpus. Even though they don't use the standard fan connector for a motherboard. They get the job done.If you're smart like me. You can build a controller for these bad boys and adjust the PWM signal to get lower fan speeds. I got it down to about 5% duty cycle and still ran 500-600rpms. I didn't really feel comfortable with that low level but I will write a monitoring function in case the fans stop rotating. 12% duty cycle will give ~1600 rpms. You can't hear the fans when they are at these lower levels. 100% duty cycle was giving me ~6000 rpms. Obviously, the fans become extremely loud and push/suck a ton of air.
