Although the voltage regulator uses 16 phases, MOSFET still needed a heatsink. Moreover, these heatsinks on ASUS P5Q3 Deluxe are surprisingly large. They are so tall that you may experience certain difficulties installing massive processor coolers.

Two heatpipes connect one of the two heatsinks on the CPU voltage regulator components with the chipset North Bridge heatsink. The latter in its turn is tied up to the South Bridge heatsink with another heatpipe.

This cooling system looks pretty cool. It seems efficient due to heatsinks with a lot of ribs. Nevertheless, it still has a few drawbacks typical of other ASUS mainboards. Namely, the heatsink ribbing and bases are made of painted aluminum that looks like copper and they are secured against the chips with weak plastic clips.

The mainboard rear panel carries one universal PS/2 connector, six USB 2.0 ports, IEEE1394 port, two Gigabit network ports, eSATA port, an optical and coaxial SPDIF Outs, six analogue audio-jacks and two WiFi antenna connectors.

Another IEEE1394 port, four USB 2.0 ports and a serial COM port are laid out as pin-connectors along the lower edge of the PCB. Right next to them there are Power On and Reset buttons that may be very handy if you are using the board in an open testbed.
