Shown here is the underbelly of Shinra's primary cooling for the quad-core Opteron CPUs: the heatsink/fan (HSF) combos with a touch of thermal paste. The HSFs used are Dynatron A5MG with 77mm ball-bearing fans and a 4.1" mounting pitch (important to fit this motherboard), and the thermal paste is Arctic Silver 5 AS5-12G which claims 3 to 12 degrees Centigrade lower CPU core temperatures on average compared to generic thermal compound.
