Loud But Powerful, Part I: TRIG T40-1-62538 And TRIG T40-3-62538
The T40-1 and the T40-3 are based on a standard aluminum heat sink that has been put together with a high-speed, loud fan from Delta.
The underside: only aluminum, albeit smoothly polished.
The underside of the T40-1 is smooth and polished, reducing the heat transmission resistance between the paste and the cooler.
The cooling capacity is quite good for a pure aluminum cooler of this size. However, its operating noise level of 67 dB(A) is borderline.
