Dust filter in push/pull setup ?

post #1 of 39
Thread Starter 
If to put a dust filter in push/pull setup, will it help to recover most of the lost airflow ? If it will work, then how much will it help? What problems can happen?
Let's take for example panty hose as a filter or HAF-X dust filters.
Im not going to run the rig with filters, I will use them only if push/pull will work.
In a push/pull will be 220mm megaflows.
It seems nice not to have dust with the same air flow.
I really want to say thanks to people on this site, I learned a lot about water cooling and other stuff. Thanks!

In my experience, it's better to NOT use a filter because it restricts airflow. I have had better luck just regularly cleaning my fans and fan grills with compressed air. Adequate maintenance will produce better results. A filter actually increases maintenance requirements and still reduces airflow.

I agree, I will clean my rig too and I will not use any dust filters, unless it's possible to do push/pull and not to lose that 10-20% of air. Maybe it's possible to recover the flow like to 95 % of original without filters? It seems there is no almost information on my question on internet.

Well, the filter you choose will determine how much airflow is restricted. You may be able to "recover" that airflow - by using higher power fans - but you'll gain noise, and ultimately, for nothing. The trouble with a fine mesh filter is that while it keeps dust from going into the machine, all the dust collects on the filter, meaning, you have to clean that filter very very regularly or you lose WAY more airflow than is reasonable. The honeycomb mesh on the front of lots of modern PC cases today does a great job of catching anything large, and the canned air handles the dust every few weeks.

Thanks for the information. I still think that it's easier to clean filter, but now I undestood that I will have to remove the push fan every time to clean the filter. Ok, of course higher power fans will increase the flow, but there is no any really reasonably better 220mm fans, than megaflows, which are going to be on the Haf-x. Also, that the point of my question not to reduce the airflow by putting one fan before the filter to push and another fan after filter to pull the air. So if you are saying power fan can increase the air flow, but maybe push/pull will too. I was hoping that this setup will not restrict so much airflow. I wanted to make the setup with a shroud too, like that:
<-Pull fan |Filter | Shroud | <-Push fan

I don't quite understand where are you trying to install the filter ,can you be more specific ?

I want to buy Haf-X and to put filters on intake 220mm fans which are located on front and side of the case. I want to try putting the push fan right after the filter on outside of the case. So, like to put the filter on intake side fan and then somehow to stick another 220mm fan on that filter. I'm having hard time explaining, because I know only russian language good enough, even that I live in WA state biggrin.gif

as general filters/mesh will reduce your AIR flow as much as 50% or more and can create extra noise but as long as you have enough air coming (220mm are pretty good size) i don't thing it should be a problem ,you can test your air flow/temps and decide what is best for your rig
P.S. i only have one filter on my 140mm intake RAD and most of my case have other vents ..it's not that bad (you can't avoid dust when it comes to static electricity ) air compressor is my friend if you know what i mean wink.gif

Why no one doesn't understand what I'm asking..I'm asking about doing push/pull on the filter.
I don't think that air flow is reduced by 50 percent because of the filter. It should be very low rpm fan and hardcore filter.
Ok, so about my question. Let's take any case and pretend that this case have a fan. This fan is located on the front of the case and we will put a filter on this fan. Then we will put another fan on this filter. Something like this:
<- Pull Fan ||| Filter ||| <- Push fan

Guys, are you just kidding or really my question is not clear?
