Solution：
We recommend users choose motherboards with power design of 4-phase, 4+1 phase or more
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)
