This is the single cooler in this review that lacks heat pipes, yet it has trumps of its own.
First, it is all made of copper. Second, it is small. And third, it is very quiet. A thermal sensor controls the speed of the fan.
The cooler’s base isn’t polished at all, though:
And the sensor resides in a very improper location – in the middle of the heatsink. Placed like that, it will sooner react to a heat dissipation growth of the graphics card rather than of the central processor.
To tell you the truth, I had expected the Cooler Master Susurro to get the last place in the end, but it helped overclock the CPU to 2.7GHz at 1.4V, and the CPU temperature was 69°C. This is not low, of course, but better than the result of the previous model. This is to show you that heat pipes are important, but also require a competent overall design of the cooler. The speed of the fan rose from 800rpm in idle mode to 2200rpm which is far from the specified maximum of 2800rpm. So, the result of the Susurro might have been even better if the sensor were located properly.
