Learn more Table of Contents Table of Contents der8auer on the Overclock3D forums has announced that he and his team are “looking at making a normal block” for the LGA 1851 CPUs because the hotpot is “quite a bit further north than it was on 1700” That means it could be far harder to cool than LGA 1700 CPUs. Popular Overclocker and Thermal Grizzly CEO der8auer has revealed on the OC3D forums that they are working on a block for the LGA 1851 CPUs. In that same post, he revealed that the hotspot on the LGA 1851 CPUs is “quite a bit further north than on 1700” meaning the effectiveness of some already available coolers could be questioned. Bad news for those worried about cooling the Core Ultra 285K. der8auer on LGA 1851 hotspot: OC.net This could mean that a cooler redesign is on the cards for many cooler manufacturers if they want to get the best cooling performance on the new platform. Cooler manufacturers tend to target the center of the cold plate as the “cold spot” which is fine for general applications, but becomes inefficient when you’re dealing with a large offset. How do you fix this potential cooling issue? der8auer said it best, if you were to be stuck with the current design of coolers forever, then you would be best off placing the inlet tube (cold water) to the north of the CPU socket in orientation, and the outlet tube (warm water) toward the south. Here are diagrams of LGA 1700 and AM5 for reference: LGA 1851 hotspot vs lga 1700 source Wccftech (hotspot shift not to scale) AM5 hotspot source Noctua Previous Next Previous Next That way, the north cold water passes over the supposed new hotspot shift and evacuates towards the south where the CPU is a little cooler. We all know that Intel’s 14th gen was hard to cool at the high end, so hearing that there could be even more trouble with Intel’s 15th generation of CPU isn’t great news. That said, if there was a major shift in the hotspot, cooler manufacturers would have likely spotted this when they were given the engineering samples for testing. So if new coolers are actually required, they also could be right around the corner.
