Topower EP-500W Power Supply Review
Cooling that is applied on today’s high-spec power supplies
is quite an important factor. We want silence and reliability, and it is not
an easy task balancing these 2 contradictory elements.
Above you see the 80mm fan for intake of air, which is placed
in an enclosed case would ultimately mean the drawing-in of casing air.
The is the exhaust fan. You can see a small hole on top of the fan. This small
hole is intended for a fanspeed control switch which is available on some of
the other models of Topwer power supplies but not this particular model.
Both fans move a decent amount of air and runs very silent. In fact they are
one of the most silent-running fans for power supplies I’ve come across. The
casing of the power supply does get quite warm after a period of use.
