New Swiftech H20-X20 Edge cooling kits

[gabe]

I ordered mine but seems you cannot do a push setup from bellow unless you do a push/pull config :/ ...

this is correct.

the current push config allows more dust comes into the case unless i'm wrong...

That is also correct, but most ppl who intall a liquid cooling system in their case are typically more interested in getting lower temps at low noise than anything else. If you are among those ppl that install gear, and never re-open their PC for a year or two after that, then by all means, reverse the fan direction so that you pull instead of pushing. That'll concentrate accumulation of the dust at the other intakes in the case where you hopefully have dust filters, that you hopefully clean off every once in a while

I for one always push fresh air into my systems for max thermal performance at minimum sound level, and do a clean-up every 6 months or so. Come to think of it, gotta do my workstation now
