The Archon SB-E's stock fan has an unusual shape and size. The frame has a mix of both round and straight edges and it measures 17 x 15 cm, so it's longer on one side. The model number on our sample reads "TR-TY170" but this is a misprint. According to Thermalright, it's a 15 cm fan, the TR-TY150. The fan has a nonstandard thickness of 26.5 mm. The blades are also unusual, not swept forward as much as usual, with rounded ends that make it look more like a propeller on marine vessel.


The smaller TR-TY140 (152 x 140 x 26 mm).

The 14 cm TR-TY140 included with the Silver Arrow and Shaman has the same shape and color scheme, but the TR-TY150's fan blades are more rectangular and overlap slightly near the motor.

The PWM drive makes the TY150 fan suitable for connection to the 4-pin CPU fan header on any modern motherboard, and it will easily start at below 400 RPM, at which speed it is silent. The noise signature at full speed is mostly wind turbulence, and too noisy for any quiet PC. At 890 RPM, it is much more subdued but still noisy, and some tonal elements are more audible, along with a lower frequency hum. The next step down brings the fan noise to a near inaudible level, but from very close up, that hum is still audible, as are some tonal elements. At the lowest speed, it is effectively silent, the close-up sound being little more than a whispery turbulence. The lowest trace in the spectrum capture below is the ambient of the anechoic chamber, which shows no significant change when the TY150 fan is spinning at 550 RPM.


At under ~800 RPM, the Thermalright TY150 is very quiet. Below 700 RPM, it is effectively silent.

°C Rise: Temperature rise above ambient (20°C) at load.

The Archon SB-E's cooling proficiency is superb for a single fan heatsink, keeping the thermal rise of our test CPU quite low relative to the measured noise. 40°C above ambient is the point where a good cooler becomes excellent and the Archon surpassed this mark, albeit only when using a large fan.

Though the stock fan might have a somewhat "muddier" sound than our reference Noctua 140 mm model, it is slightly lower in SPL and actually ran quieter at slower speeds. Our reference Nexus 120 mm fan, which often outperforms the larger Noctua, was clearly out of its element mounted on the Archon. When its speed was reduced from 9V to 7V, the temperature shot up by 6°C; the best heatsinks we've tested typically show only a 2~3°C increase. This shows clearly that the Archon SB-E is optimized for use with a larger fan.
