Thermaltake Silent939

Thermaltake Technology Co. Ltd was founded in 1999, and is known to have been the first to manufacture the turbine cooler Golden Orb for the INTEL PENTIUM III in 2000. Since then, Thermaltake has introduced a wide range of cooling solutions. Thermaltake engineers focus on performance and design. Their innovative ideas present some of the best looking fans world-wide. We had the chance to test the Thermaltake Silent939 HSF (Heat Sink Fan).

How it works :

The cooler uses a simple fan, almost the same fan as the stock cooler AMD is using. However, there are some modifications that increase performance and make the cooler silent. First of all, there are 11 fan blades (the stock cooler has only 9). This increases the air flow so that the fan does not need to spin at higher speeds in order to achieve good performance. There are 50 fins to dissipate the heat and achieve lower temperatures. The secret behind this design is again the heat pipes that Thermaltake uses, just as with the Beetle and the Big Typhoon models. However, there are only 2 heat pipes instead of the usual 3 or 6 heat pipes that are incorporated in other Thermaltake coolers, but for a low profile, small sized fan, these will do the job.

If you need further info on how the heat pipes work, you can check out the Thermaltake Beetle review.

Here are the detailed specifications as provided by ThermalTake:

Product name	Silent939
Heatsink Dimension	90.2x84.3x39mm
Heatsink Material	Copper Base & Aluminium Fin (50fins)
Heatpipe	Copper Tube diameter 6mm x 2 pcs
Fan Dimension	80 x 80 x20mm
Rated Voltage	12V
Started Voltage	5V
Power Input	1.20W
Fan Speed	2000 ±300 rpm
Compatibility	AMD Athlon64 AMD Athlon64 FX AMD Sempron Skt 939/754
Heatpipe	Copper Tube ( 6 mm) x 6pcs
Max.Air Flow	33.38 CFM
Max.Air Pressure	1.14mm H₂O
Noise	19dBA
Connector	3 Pin

The Silent939 fan speed is only 2000 ±300 rpm. At this low speed, the fan produces only 19dBA noise level, making it practically silent compared with the stock fan. Unfortunately, the fan rotation speed cannot be increased on demand, to increase cooling.

The Silent939 is designed for AMD equipped systems and cannot be fitted on any Intel based models. On the other hand, Thermaltake has a solution for 775 socketed system, the Silent775. The size of the cooler is similar to the stock AMD cooler, and the 3Pin connector seems to be very easy to install.

In a few words, this seems to be a good alternative to the standard AMD noisy cooler, and while not promising great performance boost, does make for silent operation. So, let us put the cooler to the test...
