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:
||Copper Base & Aluminium Fin (50fins)
||Copper Tube diameter 6mm x 2 pcs
||80 x 80 x20mm
||2000 ±300 rpm
AMD Athlon64 FX
AMD Sempron Skt 939/754
||Copper Tube ( 6 mm) x 6pcs
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...
