Wow. That’s all I can say about the Nexus 120mm Real Silent Case Fan.
I’ve replaced a few computers in the last two months and have been reshuffling hardware around the office. I decided that my MWave Pentium D 830 PC (vintage mid-2005), which had previously been my main production system, would now take over server duties: shared files, web apps on an intranet, and virtual machines via Virtual Server 2005 R2. In the process of making the switch I noticed that the noise level of this system had become unacceptable, and it was especially noticeable in its new location. Even with the door shut, I could hear this PC running from 10 feet down the hallway. A little careful listening suggested that the bulk of the noise was coming from a single case fan in the back. The power supply and CPU fans were both inoffensive.
I decided to replace the case fan with the Real Silent fan ($12.99 from endpcnoise.com; the total with shipping came to around $20).
It took just a few minutes to replace the fan. Undo four screws, swap out old fan, use same screws to secure new fan. The power and fan connectors were easily accessible and the plugs on the replacement fan matched the original.
When I turned the system back on, I wasn’t expecting a huge difference. But the change has been profound. When I place my hand in front of the fan’s exhaust, I can feel warm air being pulled out of the case, but I can’t hear the fan at all. I’m sure the noise level is measurable, but it’s crossed well to the good side of the noise fatigue line and blends comfortably into the background.
Generic case fans are especially susceptible to this sort of deterioration. Over time, they seem to get louder and louder. Which is why this sort of replacement can be so effective. Next up, I’ll give the same treatment to a three-year-old Dell PowerEdge server that’s buzzing front and back. If it has the same effect, I’ll have a Real Silent office for the first time in years.
