While looking at the front of the heatsink you will notice the 92mm Thermaltake fan, which has a little bit of a funnel system which allows air to be pushed over the aluminum heatsink fins. When looking at the side of the heatsink you can see the funnel action a little bit better.
On the back side of the heatsink there thirty-eight aluminum fins are used to help dissipate the heat from the heatpipes. On the top of the heatsink, you will see an imprinted Thermaltake logo on the top aluminum fin, it will also say Thermaltake across the fan housing. You will also notice the 8mm heatpipes.
On the other side of the fan, you will see the four-pin PWM power connector. On the same side it also gives you directional arrows to show which way the air will be flowing.
While looking at the bottom of the heatsink you will see the heatpipes in more detail. In the next picture you will see a copper base plate and where you would install the mounting brackets for the Thermaltake heatsink. In the last picture we have a case thumbscrew to show comparison to the size of the copper base plate on the bottom of the Thermaltake Silent 1156. Also here is a picture of the four pin PWM connector.
