Advice on system and CPU cooling

Im trying to find cooling fans that are super quiet.
I want something that has great output with minimal noise around 80mm in diameter. If anyone has any ideas please post a link or a brand name.

Thanks to all

 

RAMDISK - I bought a Swiftech MCXC370-CB, Copper base and it seems to a good job for me. You have to understand that my hearing isn't what it use to be so the noise factor isn't so important to me but it seems quiet. This is a FWIW. I'm sure you can go to some H/S fan comparison sites and get a scientific db rating as I have done but don't have 'em at my fingertips at the moment.

 

I can't give you any specifics but it may help if I can explain the basics.

By its very definition, sound is air in motion. By its very action, a fan moves air, hence it makes sound. (Noise it is sometimes called).

So, the trick is, do not move any more air than absolutely necessary. In your case, I would recommend getting the largest and best heat sink available for your CPU and installing it with the finest heat transfer compound you can get. Then get the lowest air flow fan that you can find that will still fit your CPU. I must mention that with a VERY good oversized heat sink, it is possible to operate safely without a fan (increased surface area is the key to greater heat transfer). The ideal fan would have a very low blade pitch and have a temperature biased speed control so that it only ran as fast as needed.

All the things I have mentioned are available but you'll have to do some searching to get something specifically suited to your needs.

If instead, you were referring to the fan in the power supply itself, then you have little choice there since to increase the heat sink of the internal components is not practical, you will have to accept the noise as being a necessary evil. You must have air flow through the PS and you get the noise that goes with it. The harder you paddle the air, the more noise it makes. It would be a matter of basic design and how beefy the individual discreet power supply components were that determined the amount of air flow need to keep it running without damage from heat build up. I would suggest that a more expensive PS would probably be likely to require less air than some cheaper unit. Consider replacing your PS with a higher quality unit.

And now
this.

And if you really like silence, go liquid cooled. Cheers.
