Tocools Regal From All Angles

The Fan:

The Delta fan used here is 80mm in size and protected by a fan grill. The fan draws 0.51A and rotates at around 4000RPM.The fan connects to the motherboard via a standard three-pin motherboard fan header. There is just 1.5mm of clearance below the fan, and above the square tips of the fins.

Top: With 17 fins machined from a solid block of aluminum, the heatsink is blocky in appearance. Fins are !1mm thick, and are spaced 2mm apart. Looking at the center of the heatsink we can see a glimpse of the triangular shaped base which helps to give the Regal an edge.

Side A: The side profile of the Regal shows a very simple heatsink appearance, and little extra in the way of detail. A small recess supports a bracket which the 80mm screws into. The fins are indented in a few locations, and while is hard to see, the wire clips which hold the heatsink in place fit into small slots on the edges as well.
Side B:
The wire clips Tocools to hold the Regal in place fit into the cuts in the side of the heatsink here. The fins themselves are stepped as well. The outer fins of the heatsink are 6mm thick on each side, and if you look at the base you will notice that doesn't show at all. This is because the base actually tapers down from 20mm to 1mm at the very edges.

Heatsink Base:

The base has been machined perfectly flat, and is very smooth. I really which more manufacturers would take the extra effort and mill down the base of their heatsinks as well. In the end, the consumer can use less thermal compound, and the heatsink is able to work more effectively.
