Check out this picture of my new mobo. What is that brass/copper thing? My heat sink has some of that too. My friend says it's liquid cooling.
Fanless Design
Provide a cool environment without all the baggage
Cooling fans, though a popular thermal solution, also come with noise and malfunction likelyhood. ASUS Motherboard's fansless concept is specifically created to provide a cool environment without all the baggage.
ASUS has devoted special efforts to address the thermal issues across the motherboard, and most notably the areas that reside the CPU, power, VGA, and chipsets. The heat pipe and heat sinks were tailor made to dissipate heat in the most efficient manner. <<<<< asus discription
Ok so think of this brass is better at dispersing the heat vs alunimum is there for the brass is a better way fo cooling your motherboard and its your northbridge that has the other end of the pipe.........
your board is better off for OC then one that relys on alunimum heat sinks with out a "pipe"
the pipes main function is to allow the heat to travel between two said points since brass cools faster then alunimum it will cool down faster with added fans flowing in the case. vs a heatsink that stacks the heat in one local ..
MAKE since...... ( not really good at explaining this stuff it just is there bobbing around in my head making sence till I open my mouth:withstupid
