IT House January 13 news, Intel 12th generation Core Alder Lake desktop processor has been released for some time, which uses the new LGA1700 socket. According to the test of the German media Igor's lab, the new processor and socket use a rectangular design, which will cause the central part to be under too much pressure, so that the processor along with the socket, the motherboard bent together, resulting in poor contact between the CPU top cover and the heatsink, affecting heat dissipation.
According to the schematic diagram, the LGA1700-spec fastener does not adjust with the length of the processor, and still only applies pressure at the two points in the center of the long side (red in the figure below). This causes the processor to be subjected to uneven pressure, bending inward around the pink segment.

As can be seen from the real picture of foreign media, the i9-12900K processor that has been used for a period of time has a very exaggerated bending amplitude, whether it is the bottom or the upper cover has a visible bend, although this will not cause damage to the core for the time being, but the surface is uneven, which has affected the thermal efficiency of the CPU.
Igor's lab offers a solution: the user needs to remove the metal fastener that holds the processor in place, and then install gaskets of different thicknesses above the screw holes to increase the height of the fastener, thereby reducing the uneven pressure on the processor.
In order to prevent the fixing plate on the back of the motherboard from falling off after twisting the screw, foreign media recommends that the user place the motherboard on a flat surface during operation, and then disassemble it.
The following is the motherboard after removing the clip, and the processor can always be placed in the socket without having to be taken down. Next, you need to place the four M4 washers in the screw hole next to the processor and follow the original steps to install the clip.
It should be noted that the pressure adjustment of the LGA1700 clip will not affect the stability of the processor. This is due to the fact that after the heatsink is installed, it is possible to apply even pressure to the CPU over a larger area.
Foreign media tried to use different thicknesses of gaskets, each model after installation, a complete oven test, and finally the use of HWiNFO statistics after stabilization of the temperature.
According to statistical results, the Alder Lake processor can use a 1.0mm gasket to obtain the best temperature performance after being bent, and the processor's oven temperature is reduced by 5.76 °C compared to not adding a gasket.

IT Home learned that the current manufacturers of LGA1700 slots and fasteners include Foxconn and Lotes. The problems found by Igor's lab have not been confirmed by Intel and board manufacturers. Users who have already purchased the Intel 600 Series Motherboard can refer to the above method to install the gasket for adjustment. It is hoped that in the future, Foxconn, Lotes and board manufacturers will realize the problem of CPU bending and introduce metal fasteners with less pressure.
