Figure 6a
Figure 6a shows a dual radiator setup. This particular setup was chosen to illustrate how to overcome the apparent difficulty of connecting two
radiators located opposite to one another in a chassis: one radiator in the back, and one radiator in the front. Such chassis configuration is
among the most commonly found in today’s mid-tower cases.
Notice how the radiators are setup in a parallel connection: from the MCW50 VGA cooler discharge, the tube is split into two sections, using a
Y connector. Each branch of the “Y” is then connected to each radiator inlet. Then the radiator discharge tubes rejoin into another “Y”
connector which goes to the MCW20 chipset cooler inlet, thus resuming the circuit. In this particular example, the sequence in which
components are connected to one another was chosen purely for convenience in tube routing, and dictated by the respective positions of
these components.
From a performance standpoint there is very little performance to be gained from strictly controlling the component sequence: the maximum
delta T (difference in temperature) between any two points of the liquid cooling circuit does not exceed 1ºC. Whenever possible, performance
oriented users will typically want to route the radiator discharge(s) tube(s) to the inlet of the CPU cooler, since the fluid exiting the radiators is
always the coolest.
