Thermal Integration TI-S8640L Series Heatsink From All Sides
The Fan:
With a seven bladed fan blowing air down into the 52 or so fins, the TI-S8640L is moderately noisy, but not so you would notice next to a Delta. The latch mechanism sits directly under the fan motor, and it is there that pressure is applied to heatsink during installation. The fan draws 0.35A and supports RPM monitoring when connected to the motherboard.

Heatsink Top:
 All points on the TI-S8640L lead right to the center of the heatsink. The unique layout is intended to make heatspreading as efficient as possible. The fins are spaced 3mm apart and measure 1mm thick.

Side A:
On the mounting side of the heatsink we see a clip which requires the use of a flat head screw driver to engage, or disengage. The fan attaches to a plastic fan shroud which aides in the direction of the exhaust air. The clipping mechanism is not difficult to operate, but does require tools.
Side B:
When the heatsink is about to be mounted on a processor, the an armature on the other side of the cooler would be vertical, lessening the pressure on the clip mechanism. When it is down, the clip is locked down, and the heatsink exerts pressure on the core for good thermal contact.
Heatsink Base:
The core of the processor touches at about the center of the entire heatsink, but not exactly. As the heatsink is symmetrical by design, and the core off center, things are not 100% centered, but this shouldn't have any large negative effects. The base surface is perfectly flat and machined very smooth so it makes good contact.
