I have been working to quiet down my office. I haven’t measured the noise level of my three computers because that would be just too geeky, not to say that I am not above that. I have learned to ignore the “white noise” that my machines are creating. Lately, I have been training myself to hear the noise. Whenever someone comes over to my office they notice the noise right off the bat. So I have looked into reducing the white noise. If I had to guess what the noise level is in this room, I couldn’t give you a true reading. Estimating one machine at 50 - 60 db. Is it accumulative? Add two more machine at the same level. Add a 16″ (dia.) room fan, for the combined machines heat the room by 10 degrees, easy. I think this should give you an idea of the noise level.
Quiet PCs are the latest trend. I was working toward this not knowing the cultural fact.There are even a few companies out there that specialized in quiet PCs. Endpcnoise.com, Tranquil PC, and SilentPC just to name a few. These companies are working hard to make the quiet PC common place. If you are not up for paying a company to do what you yourself can do then pay close attention.
Typically, PCs have several noise sources.
The power unit that provides power to the motherboard, hard drive and other components all emit noise. Fast CPUs, as well as some types of video cards also have their own fans that cause noise, while hard drives and CD-ROM drives also emit whirring and mechanical noises.
Users have two options to create silent PCs: they can add new accessories to their existing computers to hush them, or build a new silent system.
A typical brand new silent PC will include a power unit designed to be barely audible, a slower-spinning CPU fan with a large radiator to dissipate heat more efficiently, and drives designed to be quieter.
The PC case, which usually has its own fan to keep air circulating within the box, comes without a fan but is instead bigger so that air can escape before it overheats the components.
Other exotic materials include noise dampening material for the walls of the case, specially designed cables to maximize airflow and cases to enclose hard drives.
The Hush PC is something I wrote about some time ago, but that was the first time I realized how much noise my office is generating. Hush Technologies quieted their machines by getting rid of the fans. A novel idea for the quietest fans I’ve seen in the stores are around 25 db. Still audible to the human ear. If I could get my office to that level, 25 db, I’ll be happy. Any quieter than that and I will fall asleep at my desk. Take a listen to your computer and see if you need to move to the quiet PC generation.
