Alder Lake processors are bending, according to Intel

The LGA1700 is Intel’s first rectangular desktop socket. When placing the processor in the socket, the frame exerts pressure only in the middle of both long sides. Users observe that this mounting system causes the processor to bend, as is well seen in the translucent test in the following video:

However, the manifestations of this bending are not only visual – a decrease in the middle part of the processor worsens the contact of the heat sink, and even when using heat-conducting paste, users report an increase in the processor temperature by about 5 ° C. Therefore, some users resort to adjustments that try to eliminate the temperature rise caused by bending.

Tom’sHardware editors managed to get Intel’s statement:

We have no reports of Intel Core 12th Generation processors running out of specification due to Integrated Thermal Switchboard (IHS) changes. Our internal data shows that IHS on 12th generation desktop processors may bend slightly when installed in a socket. Such a slight deviation is expected and does not result in the processor running out of specification. We do not strongly recommend making adjustments to the socket or clamping mechanism. Such modifications could result in the processor running out of specification and could void the warranty.

— Intel

But as Tom’sHardware edited, the statement is somewhat alibi. In principle, the processor can no longer run outside the specifications for two reasons. Although Intel specifies specific boost frequencies in the specifications, it also specifies that it does not guarantee their achievement. Even if the processor only ran at base rate, it still runs within specifications. Second, the specified temperature of 100 ° C cannot be exceeded, because if the processor reaches it, it will reduce the clock frequency so that it does not exceed it.

LGA1700, the clip creates pressure only on the middle part of the two longer edges of the processor

According to Tom’sHardware, both the new Core i9-12900KS and the original Core i9-12900K reach a temperature of 100 ° C in a standard test load. Thus, a temperature difference of ~ 5 ° C between a bent / non-bent processor in situations approaching this limit means that the processor loses power due to bending and thus higher temperature and subsequent underclocking and achieves a higher boost significantly less than if it did not bend.

Despite the fact that, according to Intel, a deflection is expected, the spokesman admitted after further questions that the company “is researching all potential problems with partners and customers. [způsobené prohnutím] and provide further guidance on possible solutions. “
