Something that we take for granted with Thermaltake coolers are the Fan
Control units that they include with nearly all their heatsinks. The Venus
12 includes not one, but two control units, one for a free 3 1/4" drive bay
and the second for a PCI slot. The rheostat and wiring is included in both
so there is no need to disassemble one in order to use the other. A very
nice touch. A third form of fan control comes in the form of a thermal
diode. It attaches to the bottom of the CPU and at 20 C it will throttle the
fan down to 2000 RPM while at 55 C, the fan will reach a speed of 5500 RPM.
Here's a chart that shows the scaling between temperature and fan speeds.
