Environmental Safety Instruction
Avoid the dusty, humidity and temperature extremes. Do not place the product in
any area where it may become wet.
0 to 60 centigrade is the suitable temperature. (The figure comes from the request
of the main chipset)
Generally speaking, dramatic changes in temperature may lead to contact
malfunction and crackles due to constant thermal expansion and contraction from
the welding spots’ that connect components and PCB. Computer should go
through an adaptive phase before it boots when it is moved from a cold
environment to a warmer one to avoid condensation phenomenon. These water
drops attached on PCB or the surface of the components can bring about
phenomena as minor as computer instability resulted from corrosion and oxidation
from components and PCB or as major as short circuit that can burn the
components. Suggest starting the computer until the temperature goes up.
The increasing temperature of the capacitor may decrease the life of computer.
Using the close case may decrease the life of other device because the higher
temperature in the inner of the case.
Attention to the heat sink when you over-clocking. The higher temperature may
decrease the life of the device and burned the capacitor.
