Dealing with settling dust

post #1 of 26
Thread Starter 
Hey guys, I built this rig in Jan 2014 and I really love it but I'm having some issues with settling dust in the Corsair C70 Case.

I believe this case doesn't do me many favors combating dust first of all, there are to many useless holes in it, for instance the entire bottom by opened up for fan holes and radiators..since I am not using these at all and it seems like nobody does on this case I shoved some cardboard into both of the fan filter slots to block them off as shown.

I have my sp120's fans exhausting are pushing it through the radiator, I tested the same set up with the fans intaking pulling through the radiator with pretty lackluster temps, the exhaust method was 2-4c cooler than intaking. I also have no income ATM so I can't buy a filter to throw at the top of the case.

I think the type of case lighting I use also does me no favors, since its a directional very bright bar it illuminates everything it points at... I actually usually keep it pointed away from the components and still gives off a lot of light.


I am using 2 AF120 Led fans in the front, always kept at 1400 RPM
2 SP 120 top fans exhausting usually 1650rpm
1 stock corsair fan exhausting

I get great all around temps, but I'm really not happy with dust accumulation





dust accumulation






blocking off bottom







Do you guys think I need front fans with more air flow? Or should I filter the top, attach fans to the case and mount the radiator to the fans? Pushing intaked air instead of pulling it? I was also thinking solid slot covers can help.

I have a metro datavac but i hate using it every couple days in here and my house is not as clean as it probably could be.

there IS a reason why we generally recommend POSITIVE pressure configuration rather then negative pressure configuration. your negative pressure is sucking in all that dust w/o going through filters 1st...

you built a negative pressure configuration, so you have to deal with dust... it's just how it is. it's like so many others who said they don't care about noise till they actually heard how loud those 5000RPM fans can be biggrin.gif but by then they've already sunk $120 into those fans and have to deal with it smile.gif

Just grab a datavac on sale and never worry about dust ever again

It goes for pretty cheap on sale, saw it for $29 once

I second this motion, also, I have the air flow coming through the top, front and bottom from the outside,[all filtered] with the lone exhaust being in the back, this way, in theory, it should stop air/dust from coming through any unfiltered cracks...at least this works for me...and, my temps are good...fans at lowest settings, quite...

I have a data vac i just hate needing to clean it so often. I think I'll get better results if i put the fans in between the case and radiator instead of fans mounted under the radiator for intake

if your not using the bottom filters as you said you put cardboard there then sit those filters on top for now, I have a C70 case and I have only had to clean it 2 times in the year I have owned it.
I use all air cooling. I also have 2 140mm fans on top as exhaust.

I have been looking hard at the C70 (and a few others) for awhile now, and I have been wondering how well it keeps dust out. Just looks like it would get real dusty after a week or so, especially with the thin dust filters and all those case openings. I really love the look of the white version, but would probably have to find a thicker dust filter to use if I got it. Just not sure what.

I like the thick dust filters on the Arc Midi R2 case but not sure you'd get good air flow with a thicker filter.



The more openings you have the more potential for dust. Maybe use some color matching tape to cover those unused openings.

If you find a better solution to controlling the dust, please let us know. I certainly am interested in your solution. Dust can be a pain!

Good luck, man.

I don't even have the front filter installed for my intake fans in the front of my C70 as they are a little restrictive I only have the bottom filters installed.
I get very very little dust in my case. I do have it sitting up on top of my desk though.

You made me cry! redface.gif I live in a dusty environment and dust finds it's way into everything! I burp dust around here! tongue.gif

How is you fan configuration and how is the noise level?
