Are dust filters worth it? - Page 3

post #21 of 34
Filters reduce your airflow, which means you need higher performance fans, which are louder.

That said, we live with an African Grey parrot, who generates lots of dust. Simply putting up close mesh wire screens - they're not quite filters - has reduced my dust buildup to the point where I only need to blow out my rig once a month. See item 7 in my sig for how well the [ame="http://www.amazon.com/Metro-Vacuum-ED500-500-Watt-Electric/dp/B001J4ZOAW"]Data Vac[/ame] works. With the Data Vac I can afford to be profligate with blown air.

If we were able to filter out all the dust we would. Then the filters might not be necessary. In general I'd prefer not to have to use them.

The thing is HUUUUGE!

And, really loud when cranked all the way up, but at the lower settings it fine:

(big off-white thing in the top-left corner).



These things are kinda costly, but well worth it.

In a moment of rationality, I would wager that a few dust filters would be far less expensive and more practical.... but then again Imma not really all that practical.

Dust filters are better for people who don't want to dust out the computer as often. However, it does decrease airflow and some dust will go inside the computer. It can increase noise for intake fans.

Also, the majority of dust in homes comes from people's dead skin cells. Even if you have a central air filter system, you will still have dust.

Barring a home designed as a cleanroom, yes, there will always be some dust.

They actually make quite a bit of extra noise especially above 1000rpm (depending on the blade design of course) however I have found out that fitting a shroud between the filter and the fan reduces the noise.

This is true. You can tell what type of noise a fan will make if you put your hands 2 cm from the blades (be very careful). I noticed my S-FLEX fans made a lot more turbulent noise than my GT's with this test.

I think they're worth it. I have a 120mm side filter and now my graphics card never gets filled with dust.

A forum buddy is sending me a 200mm filter so that should keep teh case even cleaner

No fan filters or grills for me. I take my computer apart enough that it doesn't really matter, and I like to get the most airflow I can from my fans.
post #30 of 34
At least for me , yes . I can clearly see the amount of dust that comes off when i wash them .

And when i think all that dust would get on my components ... bleah !!!

Airflow restriction ? Not so much . I mean , i can still feel the air when i put my hand in front of my fans ...
