With the Silent939, Thermaltake offers a replacement for the stock AMD cooler. It doesn't promise outstanding performance, it doesn't promise very low temperatures or overclocking potentials, but it surely does what it promises. It keeps your processor cool and it does it quietly. However, we managed a 5°C drop in temperature when we put the cooler to the test, a temperature difference that is very good for such a cheap cooler.

There are no fancy lights or an extreme looking design with this cooler, but the cooler is very small indeed. It will fit with no problem in any motherboard, no matter what you have on it. If the stock cooler can be fitted, then the Silent939 can too.

The fan cooler produces only 19dBA noise level, cooling the CPU without being noticed. Installation was very easy, since the clip that secures the fan on the CPU is very well fitted on the cooler. No extra pressure is needed and we found installation to be easier than the stock cooler.

The Silent939 costs only US$37. It is a very low price for a fan cooler and is one of the cheapest coolers that offers a slight increase in performance but major reduction in noise. However, it is not recommended for enthusiast overclockers that are happy only when their CPU is on fire.

Pros:
- Low Noise (19dBA)
- Small size and easy to install
