Kuthtec KTM3000 Copper Core Heatsink Review

Kuthtec use a larger copper center than most manufacturers, extending it the full 30mm height of the heatsink, 30mm. Some heatsink designs we have seen recently have cut the copper center to about 3/4 of the full height. This apparently makes the heatsink work a little better, but we shall have to see for ourselves in the case of the Kuthtec KTM3000. Cooling fans always tend to work a little better when there are a few millimeters of separation between the base and the heatsink fins. On the bottom of the heatsink we find a rather ingenuitive clipping method. Rather than cut a big hole down the center of the heatsink body, or one of a half-dozen other methods, the engineers have devised a clip which 'bolts' onto the copper insert directly.
