When I installed the fan is my first noticed that the cable is very short.
For this is the fan nothing for the front of a long housing.
The accessory is not available in dimensions quite scarce. If EKL fan you will be treated with good and useful accessories.
Now the volume: Yes it rotates at 2000 rev / min which is quite a lot but here he makes a noise that has washed up!
He is determined a few dB quieter when he could breathe free, but still it is a loud bitch.
I have now run it with 5V because it is very pleasantly quiet.
For the cooling capacity I need not say much: The thing really pumped a lot of air, no question. Also at 5 volts with which he now runs with me it cools my Seagate Barracuda ES (which is a heat monster, uncooled 50 ° C) without problems at 32 ° C.
But must say that I still have 4 other HDDs in the housing that are not exactly cool naturally.
Who is deaf or want to run a server in a data center should strike, the cooling performance is really great!
The golf ball pattern looks good, but nothing else!
It does what it should and for people who want to bring the air accelerator sure I can recommend either a 5-12Volt Poti to buy it or a 12 to 5V adapter.
