Thermaltake is one of the most prolific
aftermarket suppliers of PC accessories. The brand is well known for the "Xaser"
line of aluminum cases as well as a wide variety of heatsinks and
newer line of power supplies. The latest trend in high performance heatsinks, driven by the prodigious heat output of the latest processors,
are very large designs using heatpipes. Never one to miss out
on a trend, Thermaltake have recently released several colossal new heatsinks
and a few of them could be of interest to Silent PC Review readers.
The Silent Tower is a large, actively cooled, heatsink that uses a
copper base and heatpipes to transfer heat to 59 aluminum fins. It's
covered by an aluminum shroud that acts as the mounting point for a 92mm fan
molded from virginal white plastic. While it looks like weight would be a problem,
it's actually not too bad at
640 grams, fan included.
It's actually lighter than it looks.
Plastic blister pack for shows the Silent Tower off in all its glory:
Good for in-store display purposes but hardly environmentally-friendly.
Package contents: Heatsink + fan, mounting hardware, manual and thermal
compound.

A glaring discrepancy in the specs is the airflow value of 52 CFM and 21 dBA. A 92mm fan that blows 52 CFM could only be measure 21 dBA if the microphone of the sound level meter was placed at least 10 feet away. At the usual 1 meter SPL measurement distance, there is simply no way it could be so low as 21 dBA. Either the CFM must be lower or the noise must be higher.
