The Thermaltake Venus 12 is a high
powered AMD Athlon64 heatsink compatible with socket 754/939/940 processors.
The heatsink is completely made of copper components, and utilizes 5500RPM Everflow fan which moves
upwards of 72CFM at full speed. The 760 gram heatsink is heavy, but
its tool-free clip mechanism locks onto all three tabs of the K8
retention frame solidly.
The Thermaltake Venus 12
heatsink comes with two different fan speed controllers, one on a PCI slot
bracket and the other in an aluminum 3.5" drive bay bracket. Both fan
speed controllers have the same effect when plugged into the Venus 12's
fan. Their use is not mandatory, and the controllers can be unplugged from the fan.
As with most of Thermaltake's offerings, the model A1744 "Venus 12"
is competitively priced.

A bundle of
wires exit from the large 80x32mm Everflow fan, half of which are for controlling it. Due to the fans' high-power requirements, a molex connector is used instead of the standard 3-pin
The heatsink package includes a Kapton encapsulated thermistor among its contents.
thermistor enables the fan to thermally throttle its speed based on the
temperature feedback from wherever the 12" long sensor is positioned. This kind
of passive control limits some of the noise output created by the Venus
12's high-powered fan, while delivering that extra kick when temperatures rise and it is genuinely required.
control of the fans' speed can also be used with the thermistor attached,
or without it. Thermaltake have bundled in two separate fan speed controller potentiometers, with brackets for front and rear computer mounting.
