Also visible are the pair of medium sized claw shaped heatsinks used to cool of seven components screwed to them. In the past Fortran has handled the responsibilities for making all of Zalman's power supplies, but check the number of the back of this unit with the Underwriters Lab database it turns out the power supply is listed as being a Zalman unit. However looking at the largest transformer in the power supply the letters SPR are on it and we know from our experience that this is a Sparkle transformer. For the record Sparkle is part of Fortran power supply.
The sole purpose of this picture is so you can see the area to the right, here you can see the heatpipe with the generous amount of thermal paste applied to the contact points where heatpipe bends its way back around through the fins. This is smart thinking on Zalman's part to make sure that the maximum amount of heat can be transferred from the circuitry and then with the aid of the 120mm fan the air that is being exhausted from case will be blown across the heat pipe to help cool it.
So what is a heatpipe, since we are going to be discussing one here in just a minute perhaps we should find out exactly what they are and how they work. Basically a heatpipe is a hollow cylinder filled with a vaporizable liquid. The heatpipe tube itself has two completely different ends to it, one is the condenser and the other is the Evaporator Once the evaporator become hot enough that the fluid turns from a liquid to a gas the will gravitate to condenser end where it changes back into a liquid after it has a chance to cool and then it is wicked back to the Evaporator section to start the process all over again.
Here is a far better view of the Heatpipe itself you can see in this picture that the heatpipe actually runs across the rear of the power supply and then hangs a left at the green torodial coil and is attached to the aluminum block that has numerous FET attached to it along with the power transistors.
