hi,
im just wondering how loud is my no name AMD fan, or rather how loud are the dbA specs of the fans im about to buy. I don't have any idea how loud are those dbA specs, but if u can tell me how loud is the p3 750mhz bundled fan than (because i'm using it, and a much fan quieter fan than my AMD's), then i should get an idea.


thx

I have a few 28db fans and they are nearly silent, and I'm pretty sure every 3 db's you increase the sound doubles. I could be wrong though. Which fan are you looking at getting?

Here is a list of many of the heatsinks included as retail heatsinks for AMD processors. Note that the decibel levels are generally between 36 and 42.

OK, well, we can't help with the heatsink you already have, then, but you can probably assume it's similar to one of those I posted.

If you tell us what heatsink/fan you are planning to buy, we CAN help you with that, though.

That depends on where you start. If you are going from 28 to 31 there is almost no sound increase. But if you were going from 120 to 123, that would be more than twice the sound. dB's arn't linear.

For every 3dB the sound pressure doubles. For every 10dB the noise to human ears doubles.

Sorry none of these replies help you..

The AMD Stock Heatsink weighs in at 53dbA, as found [link=[URL]http://www.overclockers.com/articles471/]here[/link[/URL]]

I wasn't able to find the sound specifications of the P3 stock heatsink though. It is very quiet, yes, because it doesn't need to be louder or provide more cooling.

What are you running the stock P3 heatsink on? What AMD?

53dba!!! ... are you sure?

I thought that was about what deltas were. My cpu fan runs at about 33dba, and its better than the stock cooler.

57 decibels 8" from the fan. Most fans are measured at 1 meter, or almost 5 times that distance.

Using this tool, you will find that it would be almost 14 decibels quieter.

In other words, 43 decibels.
