Intel’s 12th-generation Core processor interface has changed from LGA 1200 to LGA 1700, the shape of the CPU has also changed from a square to a rectangle, and the locking method is also different from before. In fact, when we tested it, we found that the lock of the LGA 1700 is significantly more stressed than the LGA 1200, but we did not expect it to bend the CPU and affect the cooling effect.
igorslab found this problem during the test and gave an improvement method. Compared with the previous LGA 1200 socket, the LGA 1700 socket is larger and the pressure of the lock is greater, but the fixing method of the CPU is the same, the force point is still on the winglets on the two sides in the center of the CPU, in fact, the slot of the LGA 2066 is larger, but the stress points are on the four corners of the CPU, which is much more uniform than the LGA 1700 as a whole.
The result of this design is that the CPU is easier to bend. In fact, igorslab shows a CPU that has been used for hundreds of hours. From the above picture, you can see that the central PCB of the CPU is significantly bent downward.
The CPU top cover also has this problem, but the top cover itself may have a certain curvature, not sure if this is bent, but this will inevitably affect the contact with the heat sink.
