Recap: When Intel launched Alder Lake final 12 months, some customers shortly observed a fault: the brand new socket’s built-in loading mechanism (ILM) pushes down on the CPU from solely two small tabs, inflicting it to bend in a means that separates the CPU from the cooler and will increase its temperature.
In January, Buildzoid from Truly Hardcore Overclocking developed a simple resolution: including skinny washers to the screws between the motherboard and ILM that cut back the stress exerted by the ILM to a stage that does not bend the built-in warmth spreader (IHS).
Igor’s Lab examined it then and located that it supplied a couple of 5° C temperature lower with the 12900K. It turned the de facto resolution for overclockers that did not need to delid their CPUs (a well-liked choice with the 12900K), however as a result of it additionally reduces socket stress, it will possibly trigger minor issues.
Thermal Grizzly is now producing a extra polished resolution in collaboration with legendary overclocker Der8auer. It is a Contact Body that replaces the inventory ILM and gives even stress to all 4 sides of the CPU. It is also capable of deflect the strain within the IHS to the perimeters, bettering the contact within the heart between the die, IHS, and cooler.
Inventory ILM
Der8auer made a video concerning the body earlier than it was launched, which explains the way it works in additional element. In his testing, with a lapped EKWB Magnitude water block, it supplied a 7° C temperature enchancment at greatest and 3-5° C of enchancment normally, relying on the CPU he used.
It seems that the helpfulness of the Contact Body varies with the CPU and cooler relying on how flat they’re to start with. Some CPU coolers made for Alder Lake come from the manufacturing unit with a slight curve to stability out the bend within the IHS, and Igor’s Lab’s current evaluate discovered that they do not profit from the Contact Body.
Of their testing with three completely different fashions of CPU coolers, Igor’s Lab found that the body supplied an enchancment of 10° C with one, 6° with one other, and had no impact with the third. Nonetheless, the most effective two temperatures they bought, roughly 60° C, have been with the body.
Thermal Grizzly Contact Body Through Der8auer
Igor’s Lab additionally examined one other resolution, the Alphacool Apex Backplate. It helps the socket from beneath and makes it extra inflexible however is not fairly as efficient because the Contact Body: in testing, it solely supplied a 5° C enchancment. It is also solely appropriate with Alphacool {hardware}.
Nonetheless, the body is not essentially the higher product. Each Der8auer and Igor’s Lab warn that it will possibly apply an excessive amount of stress to the CPU within the socket, inflicting it to make a foul connection to the motherboard that may usually lead to reminiscence instability. The answer to that is to reseat the reminiscence and dial again the stress by loosening the screws, nevertheless it’s tedious.
The Contact Body additionally runs about €40 ($43), which is lots for a small aluminum bracket. The Alphacool Apex prices about $15. If you’re discovering that your 12700K or 12900K is cooking, although, selecting one or the opposite up — and even making an attempt the $5 washer trick — may be price it.
