News Arrow Lake hotspot purportedly moves up compared to LGA 1700 — Der8auer preparing water blocks for Core Ultra 200 series

[Admin]

Arrow Lake's hotspot characteristics have purportedly changed compared to Alder Lake and Raptor Lake. The Core Ultra 200 series LGA 1851 format has purportedly moved hotspot temps north compared to where they were before.

It might be interesting to revisit TR Peerless Assassin 140mm and Noctua D15 G2 on these new chips.

I knew there would be an offset and find it interesting that Intel opted for North while AMD has used South. It makes me wonder what the new cooler market will look like since there won't be new CPUs sold with the center being the heat source anymore. I imagine Noctua has probably been checking possible mounting offsets like they have had for AMD. Then there's also the LFIII which has an integrated contact frame which I imagine means they can't do any offsets. This is a concern I had when Arctic revealed the design, but will definitely need testing to find out whether or not it matters.

It'll be interesting to see if reviewers need to revamp test setups again for tiles. I know several have just updated to 13th/14th in the last year.

If I were designing a heat-sink block, I would design it as if the hotspot covered 100% of the CPUs heat spreader.

So, a vapor chamber.
Too bad that DeepCool Assassin 4?5?6? with VC prototype will never make it outside of China.

Aside from the vapor chamber approach mentioned by @Notton , the problem with your idea is you need a really thick baseplate of the cooler, in order to transfer heat from any part of the IHS to all of the heat pipes. However, the thicker your baseplate, the more thermal resistance it has, which hurts cooling efficiency.

Speaking of coolers with vapor chambers, it seems there have indeed been some recent announcements in this area.
