The base of a heatsink and the method by which it is installed are as important to overall performance as construction material and/or form. In these regards, Thermaltake simply follows convention.

Smooth, flat copper base.

The base is smoothly polished and flat, although there are some very fine circular ridges visible close-up that we weren't able to capture it on camera.

Under the mounting plate.

The base and heatpipe assembly are attached to the mounting plate with four tiny screws, making it simple to remove. The heatpipes are permanently joined to the base, presumably with solder. There was no thermal interface material between the top aluminum cover and the heatpipes or base. Spreading some TIM in this interface might improve cooling a tiny bit by spreading out the heat a bit more efficiently, perhaps by a degree or two. It was left as-is for the test.

Accessories and mounting hardware.

The LGA775 push-pins are split into two brackets and are secured with screws. For AM2/K8 installations, a simple metal tension clip is provided.

LGA775 legs attached.

The push-pins engaged the heatsink against the CPU with moderate tension, similar to the stock Intel heatsinks. The base could be rotated a few degrees, but overall it was a pretty snug. Using the push-pins was simple because there was direct, unhindered access to them from above. We ususually bemoan the use of the Intel-designed push-pins, but in this heatsink, it was not an unwise choice. Only the cantilever effect of the 637g mass, a lot of which is positioned at the top (or end) of the heatsink, would give us any cause for pause.

Installed with the fan turned on.

The heatsink did not have any compatibility problems with our test board. The angle of the heatpipes is high enough to clear most northbridge heatsinks. The V1 did overhang the edge of our motherboard by approximately 2.3 cm (or almost a full inch) at its furthest point. This could run foul of the power supply in many cases.
