The Silent Tower has 59 aluminum fins and has heatpipes through its center. If you're unfamiliar with heatpipes, here's an explanation.
A heat pipe is a vacuum tight copper tube, with a wick and cooling fluid inside. As one heatsink gets hot, the heatpipe heats up as well. This turns the liquid into a high pressure vapor that moves toward the cooler side of the heatpipe, as the vapor reaches the cooler heatsink, it condenses and releases the heat to that heatsink. The wick helps move the liquid.
Connected to the heatpipes is the heatsink base which is made of copper. The base has four screw holes for installation of the heatsink.
Above are the various components to install the Silent Tower. One draw back though, regardless of which cpu type you have is you'll have to remove your motherboard from the case to install it. That's because the Silent Tower mounts to the motherboard and not the cpu socket.
This method will however, give you a more solid attachment point for the heatsink, than the typical 3 lug system.
Test System
AMD XP 2600+ 333 MHz (AIUHB)
Asus A7N8X Deluxe rev 2.0
Corsair PC2700 XMS 512 MEGS
Thermaltake Damier 5000A Case
Western Digital 80 gig 8 meg cache harddrive.
To calculate the idle temperatures, I gave the computer 10 minutes on its own before writing the temperature down.
Next, using Sandra burn in wizard I allowed it to run 30 minutes and recorded the readings.
We will be comparing the Silent Tower to the Zalman CNPS7000A-CU Heatsink.
From the results we see the Silent Tower didn't defeat the CNPS7000A-CU Heatsink, but still came out with some good numbers.
The Silent Tower, as you can guess from the title is aimed at silent cooling and it does just that. The fan noise is very quiet and barely audible.
If you're looking to setup a silent computer system, the Silent Tower could be what you're looking for.
