a way to reduce dust inside the computer

Recommended Posts

Posted · Original PosterOP

does putting all your fans in your case to push air out of the cause reduce dust inside the case? And is it a good idea to have every fan in the case pushing air out of the case

You want to have a higher intake than outlet of air in your case to create positive air pressure which should help keep dust out.  Have more fans or a higher airflow in to the case than out of it.  Having all of your fans pushing air out of the case will draw dust in through other gaps as the air has to be supplied from somewhere.  What case do you have so I can help suggest which way and where to mount your fans?

but if all or most of the holes in the case are blocked by fans pushing air out of the there is no way dust can get in right?

@pvknbd Your fans and case panels don't create a perfect seal, dust will enter the case as air is drawn in to it for your fans to exhaust.  How many of the fan mounting positions do you have occupied with fans?  Do you have any on the side panel?

It can be done and you will achieve a mostly dust free environment in the case, it's called negative pressure and it's frowned upon, do it and tell us how it goes with regards to temperatures etc.

I believe you mean positive pressure.

 

When you have more air going in than out, that means the pressure inside the case is "higher" than on the outside, thus, every hole/gap on your case will exhaust the "extra air" inside the case. Negative pressure is the opposite.

 

Some argue about which's better but, to be honest, it depends on the case, the room your case is at(dusty or not, hot or cold, etc)...

 

To keep dust out, make sure to have all your intake fans filtered and, if you want, your exhaust fans too. Regarding negative and positive pressure, I would try positive first and check the temperatures. If they're fine, keep that way. If they are not, try working on your airflow and so on.

these are my idle temps with all fans pulling air out of the case

nope

Have the two fans on your side panel as intakes and the rear fan as an outlet then, this should reduce the amount of dust getting in to your case.  If there is still an accumulation of dust you can add a filter to your fans to trap it.

And load temps? What were the temps before you changed the fans around?

Another thing is you need to let the system run for a while to get hot and see what the real temperature would be, run a stress test on CPU and GPU for an hour or so and then come back with temp readings

i actually used that case for about a year i found the best solution was to have a fan in the front as intake 2 in the top as intake and one in the back as exhaust, i also modded the the side panel to be a full clear window without fan mounts.
