Thermaltake
has examined the effects of power supply fan RPM's
(revolutions per minute) versus temperature, and also
for fan voltages and how they are affected by temperature.
The graphs Thermaltake provided are included in the
insets below for your edification.

It's time for
a more thorough examination, don't you think? Let's
get out the surgical tools and do a frontal lobotomy
on this beast and see what it's made of.
The picture
above shows the 3 connectors, PCIe (X2) and 8 pin
Power from the PSU to the Power Station. The picture
below is the beginning of the examination with the
top cover to the power supply carefully removed.
Stamped proudly
on the side of the PSU is Thermaltake's outputs on
the individual voltage rails. Note there are 2 separate
15 amp +12 volt rails on this particular power supply.
The picture below shows the top off the power supply
with the fan resting atop the bevy of aluminum heat
sinks below. Let's dig further, ok?
Below left,
you can see the left side of the power supply with
circuitry exposed. On the right side is a close up
view of the 7 aluminum heat sinks that Thermaltake
attached to cool the PSU. The 2 pictures further below
show the coils and other parts used on the main circuit
board.
Above we see
depicted a large electrolytic capacitor rated to 450
volts at 330 uF. Capacitor electron storing ability
(called capacitance) is measured in Farads. One Farad
is actually a huge amount of charge (6,280,000,000,000,000,000
electrons to be exact), so we usually rate capacitors
in microfarads (uF = 0.000,001F) and picofarads (pF
= 0.000,000,000,001F ). Capacitors are also graded
by their breakdown (i.e., smoke) voltage.
