Thermalright Offers a Solution For Alder Lake Socket Warping

Thermalright is the company offering the cool-looking BCF (Thanks Cowcotland). It’s made from CNC machined aluminum and it comes in red or silver. From what we can tell, it replaces the entire retention mechanism on an LGA 1700 motherboard. With it removed you just drop this sucker down onto the socket and screw it into the backplate. This should alleviate the warping issue, which Intel says “is being caused by the mechanical load being placed on the motherboard to make electrical contact between the CPU and the socket.” Intel says even though there might be some warping, it won’t cause the CPU to run out of spec. Unsaid in its statement is that even a very slight warp can cause a gap between the CPU’s heat spreader and the cooler. Although this is what thermal paste is for, it’s not meant to fill gaps, so cooling performance can be reduced.

As proof of this situation, Igor’s Lab originally brought this issue to light by adding washers to the LGA 1700 socket. He noticed that Integrated Loading Mechanism (ILM) was placing uneven pressure on the Itegrated Heat Spreader (IHS). This is what sits on top of the CPU die. Over time this resulted in a slightly concave or convex shape, resulting in a tiny gap between the IHS and the cooler. He discovered that by raising the height of the socket 1mm, he was able to reduce the warping he measured in Alder Lake CPUs. By using a set of 1mm washers, he was able to lower full-load temps by 5.76C, which is a decent gain. It’s especially notable as upgrading your expensive cooler might net you that, but this was done with four cheap washers.

Intel has stated it has no plans to change its current socket design. However, it is interesting that the problem now has a 3rd party solution. This seems to point to the fact that enough people are annoyed by it that they’re seeking remedies. According to Videocardz, the BCF only costs $6 USD too, so it’s pretty cheap. Of course, Intel warned its users that attempting to modify your motherboard’s socket might void your warranty. We’re not sure if this falls into that category but removing the ILM probably does. That said, we’ll have to wait and see if more of these types of fixes show up stateside. Perhaps if they do it’ll put pressure on Intel to announce a revision to its socket design.

Sony has announced that it will pull Cyberpunk 2077 from the PlayStation Store and award refunds to anyone who wants them. Meanwhile, events of the past week have proved CD Projekt Red misled investors as to the state of the game when it announced the last three-week delay in October 2020.

New Beagle Board Offers Dual-Core RISC-V, Targets AI Applications

Budget RISC-V hardware is on the way, and it's a heck of a lot more affordable than anything we've seen in the past, with just enough CPU horsepower that a hobbyist might be able to do something with it. Later models may compete with chips like Raspberry Pi, though likely at higher cost.
