Foxconn NBT-CMI7759B C - The Design Snafu
You can see at a glance that the NBT-CMI7759B C made by motherboard manufacturer Foxconn is almost identical to the classic box cooler that comes with Intel processors. This is the high-performance version of that design, using a large copper core and fine aluminum cooling fins.

The noise generated by this model is also identical to that of the box cooler, and the two also share the automatic fan speed regulation feature (PWM).
At 86°C, cooling performance is also on par with that of the box cooler. When idle, the fan is barely audible from within the closed computer case.
That begs the question: who needs this cooler? The price gives us an answer, really. Costing just shy of $13, this is the ideal replacement should the box cooler fail, for example if the push-pins break off.
Since the fan conceals the push-pins, these can't simply be released using a screwdriver. Apparently, someone missed this fundamental design snafu during the QA process. In the worst case, users may be unable to remove the cooler from the board, if it is mounted in a cramped case.
