AMD should've redesigned their IHS for AM5. It would've broken legacy support, but now they are stuck with a thick IHS for the lifespan of AM5, making it even harder to deal with the heat density issuess.
Now obviously this 'story' is about trying to reduce the heat density to begin with, but that's a far bigger challenge and a problem everyone has. While changing the IHS and cooler compatibility was something AMD could've easily done.
Impriving the thermal compound for the IHS would be a good start. Liquid metal can bring down temps by abotu 10C peak temps which is a lot, I understand liquid metal isn't really all that reliable and doesn't last all that long but even if they improve the compounds to where it can drop temps near that it would be a big deal.
I still wonder about the feasibility of integrating a vapor chamber in that thick IHS!
A cool idea but AMD would rather break compatibility than pay for something like that.
Aye certainly. Was thinking more about 3rd party solutions however, might be something der8auer or the likes could build!
Perhaps the localized heat flux is just too great though.
Gamers Nexus had a tour of AMD. They actually developed and validated a vapor chamber IHS, but said it wouldn't be worth the cost. Their whole cooling lab tour was super interesting.
yea how are you supposed to have a fan curve when its idling at 50c. i do anything with my 7600x and it heats up and the fans on my ak620 ramp up and down. its as annoying to sit next to as a stock cooler.
The fully integrated backplate breaks compatibility with half the AM4 coolers anyways. They should have taken the full plunge and made the IHS thin enough so that the CPU wouldn't throttle under load.
