for CPUs that demand 89W or 95W power consumption.
We recommend users choose motherboards with power design of 5-phase, 5+1 phase or more
for CPUs that demand 125W or 140W power consumption.
Subject 2: Suggestion on choosing electric fan
Both the amount of electric current to MOSFET and the heat produced from the
motherboard go up as AMD's CPU power consumption increases. In this case we
recommend users select a CPU fan with air outlet towards MOSFET so that CPU fan
can carry away heat produced by MOSFET, for better heat dissipation effects. At the
same time we suggest using well-ventilated cases to maintain temperature as 38℃
approximately inside.( 38℃ is recommended by CPU manufactures)
Figure 1---- CPU Fan can not blow off the heat produced by MOSFET. We suggest not to
