of the Silent939 was very simple, even easier than the stock cooler that came
with the AMD processor. We used an ASUS A8N-SLI Deluxe motherboard with an
AMD 3500+ CPU. Thermaltake includes an installation guide and the thermal
compound needed to install the fan cooler. There is no need to unhook the
motherboard or unscrew anything.
After disassembling the old cooler, and cleaning all the old thermal compound,
we put a small amount of compound on the CPU's heat spreader, covering the whole
surface area on the CPU with a thin layer of compound. You should try to spread
the compound uniformly on the CPU heat spreader in order not to have small air
bubbles trapped in the thin layer.
We then placed the cooler on the CPU, as shown in the images above.
The whole procedure was indeed very simple. the images speak for themselves.
As you can see, the overall size of the cooler is rather small.
