We’ve seen a couple of solutions to this issue already. The fellow who broke the story, Igor Wallossek, advised friends to use 1.0mm washers between the CPU’s loading mechanism and the motherboard. This reduces the amount of loading force that the frame exhibits on the CPU, which in turn reduces the amount of bending.
We wouldn’t consider ourselves extreme overclockers here, so we have not validated this claim. However, der8auer has a possible solution he’s promoting as well, offering the Thermal Grizzly CPU Contact Plate, which is functionally similar to the Thermalright bracket we looked at before.
Alternatively, you could try to solve the problem another way. Alphacool sells a specialized backplate for its liquid-coolers called Apex that is much thicker and stiffer than the stock backplate. In this way, it can help prevent bending due to the immense twist on the CPU socket.
Igor’s Lab tested both the Thermal Grizzly plate and the Apex plate, as well as both together, and compared them to the OG washer mod. The Thermal Grizzly plate came out the best, with an over-10ºC decrease in CPU temperatures. Meanwhile, on a lapped CPU with a lapped cooler, der8auer was able to reduce his Intel CPUs’ junction temperatures by as much as 7.1ºC. If you’re thermally-constrained on your LGA 1700 CPU overclock, you might want to look into one of these plates or the washer mod, because these gains are legitimate.
Intel’s forthcoming Raptor Lake CPUs are going to use the same LGA 1700 socket, because they’re slated to slot right into existing Alder Lake motherboards. It will be interesting to see if they suffer the same sort of issues with bending and cooling. Hopefully Intel can get the situation sorted for next generation 700-series motherboards.
