At least, it can be solved easily, if you are willing to put a little effort into it.The best result can be achieved in our tests with a thickness of 1.0 mm with 70.88 °C and thus an improvement of 5.76 °C
The IHS is getting bent, leaving an airgap. It should be serious but only around a 5 degrees celsius improvement with washer mod? Doesn't make sense. The gap should reduce heat dissipation significantly but apparently, that's not happening.I mean where are you getting the lapped heatsink thing? It's not a bowed IHS, it's a bent socket.
The bent heatsink is only a problem if you have a perfectly flat heatsink, which likely means a lapped heatsink. Most consumer heatsinks are already curved (convex) for exactly this reason, to maximize contact area with the slight curvature of the Intel heatsink. This is not something new, heatsink curving on Intel (and sometimes AMD) sockets has been around for a long while now. This includes DIFFERENT types of bending depending on socket (convex, concave, double wave), it all depends on the type of socket retention.I mean where are you getting the lapped heatsink thing? It's not a bowed IHS, it's a bent socket.
The Noctua NH-D15 heatsink has a machined nickel-plated copper baseplate with a surface roughness of approximately ~16 microinches. The base plate is machined perfectly flat in one axis and very slightly convex in the opposite.
The Noctua NH-D14 heatsink has a machined nickel-plated copper base with a surface roughness of approximately ~16 microinches, which is considered very good. The base plate is machined flat in both axis.
and another comment from Noctua support on lapping, dated 5 years ago:Why is the cooler’s contact surface slightly convex?
As the Integrated Heat Spreaders (IHS) of today’s CPUs are slightly concave, the cooler’s contact surface has been deliberately designed to be slightly convex in order to ensure optimal contact. This way, more contact pressure will be applied at the centre of the IHS directly above the DIE, which results in better heat transfer and improved overall performance.
Apart from that, lapping the CPU/ IHS outside the socket doesn't help, as it gets deformed once installed inside the socket. If you would like to have the best performance with a lapped heatsink, you would have to flatten the CPU when it is installed inside the socket.
The entire IHS is bending? I doubt that! It's more likely that the socket retention mechanism is changing the lie of the HSF due to the bent socket.The IHS is getting bent, leaving an airgap.
The entire IHS is bending? I doubt that!
Our internal data show that the IHS on 12th Gen desktop processors may have slight deflection after installation in the socket.
It's bending, Oh God, it's bending!Reading between the lines here, they are essentially saying “it might bend a little, sure, but that won’t cause it to run outside of its specification.”
The PCB would probably crack before that happened. I don't know if you've ever tried to chop through that stuff, but it's stout. Really if the IHS were to bend to any considerable degree, the first thing to go would be the solder.Wouldn't there be more chance of the IHS adhesion getting compromised, essentially delidding the CPU?
Intel has finally commented on the Alder Lake socket flexion situation. The news might not be what enthusiasts were hoping for.www.extremetech.com
It's bending, Oh God, it's bending!
Not surprising since there isn’t a much situation where both the CPU and the GPU bring pushed to a max power at the same time.
MSI unveils Titan GT77 and Vector GP76 gaming laptops with up to Core i9-12900HX, RTX 3080 Ti graphics and 250W power - VideoCardz.comMSI shows off next-gen mobile gaming laptops The ultra-high-end laptop market is growing by the day. MSI is set to launch its new TITAN, VECTOR, RAIDER and CREATOR laptops very soon. In total there are four new designs all equipped with Intel 12th Gen Core Alder Lake-HX processors and up to...videocardz.com
Here's an example of an 150 W 12900HX and 150 W 3080 Ti mobile. Sounds like you "only" get up to 250 W between the two though.
