The board can be used either which way but you need to keep in mind that the board's VRM cooling, if taxed high, will need cooling from a custom loop or rather a method to migrate the heat from the VRM's via the ports into a cooling loop.
If your overclocks will not be high, you're good with the cooling assembly passively cooling, though just make sure you have an airflow going across the VRM's.
It has big enough heatsyncs that the VRM temps will be fine even with liquid cooling. Also, case fans will help VRM temps.I don't plan on really overclocking. at least not until I decide to do a custom loop. Decided to get the MB as I got it brand new for under $299.99 So I should worry much about the VRM cool only if I'm Overclocking?
