Stock Fan Measurements
The Thermalright TY-140 fan is a 140 mm model with 120 mm mounting holes and a sleeved 4-pin PWM cable. Our measurements put its weight at 160 grams. The dimensions of the unusually shaped frame are 152 x 140 x 26 mm.

The fan blades have gentle curves, rather than the sharp edges of most other fans. The angle between the struts and trailing edges of the fan blades is near-perpendicular, which tends to reduce tonality in the noise signature, and makes for a better sounding fan.

As you would expect from a 140 mm fan with a relatively low rated speed, our TY-140 sample was very quiet, measuring 19~20 dBA@1m at its nominal speed in our GPU cooler test system, which has a noise floor of 14 dBA. While it is a PWM model, the fan speed decreased fairly linearly with voltage, dipping down to just above 600 RPM at 6V, at which point it became effectively inaudible in our system. The fan's acoustics were soft, smooth and pleasant, except for an unusual rattle that developed between 8V and 9V (it sounded worst at about 8.5V).
|
The Thermaltake Shaman measured 15 dBA@1m at 7V in our GPU heatsink test system.
|
The wave form above shows a lot of noise at lower frequencies, but this is caused mainly by the other components in the test system. The contribution from the Shaman were in the 500 to 1500 Hz range, with no tonality when the fan was set to 8V and below.

The Shaman fares very well against the Accelero Xtreme Plus, Arctic Cooling's premier GPU heatsink, more or less matching its performance at similar noise levels. The one exception was when both coolers were set to maximum speed: The Shaman produced equivalent cooling while operating 4~5 dB quieter. Both are exceptionally efficient heatsinks capable of cooling our overclocked HD 5870 card with minimal noise.
