Case fans - something good, quiet and dust-proof!

[x0160768]

So I have a system that I've been using for a while now but I am looking to improve the airflow in my case a bit. Currently it has no case fans (it's a pretty old case) and relies just on my PSU sucking air out with a few empty PCI slots in the back for extra air movement. What I want to do is add a case fan at the front bottom of the case to pull some air in. One problem is that I get quite a lot of dust in my room so would need a good dust proof fan. Can anyone make any suggestions?

Thanks.

The dust problem can be solved quite easily. You take the vacuum out every once in a while and clean up.

Case fans don't need to be excessively powerful, as you have noticed without fans the system runs fine. You didn't specify though what size of a fan you're looking for.

In the case of 120mm, Noctua NF-S12-800 is my one and only choice as case fans. It runs at 820 RPM, pushing air at respectable 41 CFM at that speed and consumes very little power, 0.59W. It is the quietest fan tested at silentpcreview.com. Some say it's a bit more expensive than others but I wouldn't know anything about that, I don't live in the US.

If you're looking for smaller fans, then take a look at the site mentioned above and see for yourself. They aren't quite as effective as case fans and are noisy.

yeah you just have to clean. There is no such thing as dust proof when you are flowing standard room air into an enclosure.
