Push - Dust Clogging?

[blankoos]

Is it really true that a push configuration will clog more dust in the radiator than a pull one?

[JeffreyEagan]

They both have the chance to clog the radiator, pull is easier to clean, push, you'd have to remove the fans to get to the rad.

Yes, this is true. The best air solution is slightly positive air pressure, where there is slightly more intake than outtake. For example, if you had five total fans in your system, the ideal solution would be for three intake fans, and two outtake fans. This results in much less dust buildup. 

 

This is about push vs pull, not positive pressure vs negative pressure (though that is somewhat related).

 

Push vs pull makes no difference to the amount of dust, but pull is easier to clean since the fan doesnt cover the side that will get dusty.

Not really what I was asking for but yea, I know, thanks.

But OP, this^ wont be a problem if you have positive airflow and all your intakes are filtered or you have negative airflow but there are no unfiltered ventilation holes on your case.

Dust always gets in, no matter what. It's just much less that way.

Ofcourse, no question about that. You should be cleaning out your case atleast once a year even with full system coverage of dust filtering.

Good to know!

All intakes are filtered and I'm going for a slight positive air pressure in the case! Thanks ^^

Actually my rig still looks brand spanking new on the inside and I've only ever cleaned the filter (about every three weeks)

Nice to hear that! Also every household will have different situations, I would have to clean my filters and case more often because of our cats

Tbh maybe it's just my filter being finer than most. It's a piece of pantyhose stretched over a frame after all. It does clog after a relatively short time but it does pretty much what it was meant to do. Also, there aren't any fan mounts in the top so no dust can fall in when the system is powered off either.
