The push-to-lock pins employed for this heatsink were designed originally by Intel for use on their stock heatsink, whose dimensions remain inside the perimeter set by the pins. This means the pins are easily accessible from the top on almost any motherboard. Not so if the pins are used with heatsinks that have fins extending over the pins. The Asus Triton 75 is such a design, as all the photos have clearly shown. You have to reach under the fins to get to the pins.
Locking pins were made originally for this heatsink design.
It was not until this phase of the testing that the fangs or claws mentioned on the previous page were noticed. What function could that little protrusion from the fins in each corner possibly serve? Certainly the effect on cooling with the extra bit of fin surface would be utterly trivial, so better thermal performance is not the goal. No, we can verify without a doubt that the sole intended function of those fangs or claws are to draw blood from the fingers or hand of the DIY enthusiast whose satisfaction will surely increase from doing battle with the Triton 75... especially the fangs closest to the heatpipes where they emerge from the base. The result of our bloody battle is shown below, with the heatsink securely mounted on the heatsink testing platform.
Installed on standard test motherboard.
Clearance around the CPU socket is not an issue; the bulk of the heatsink sits
well above the motherboard. The overall size of the fins could be an issue, however, depending on the layout of your motherboard. On ours, the CPU socket is very close to the "top" edge of the board. With the Triton 75 mounted as shown, the fins hung over the the "top" edge by at least an inch. This would interfere with the power supply on that side in most cases.
There was no way we were going to do any load testing without a fan, so our reference fan was installed using the provided wire clips, which are easy to use.
Because they go over the thickness of a 25mm fan, whether the fan has closed or open corner flanges is not a concern.
Ready for testing.
