I am wanting to order some stuff to do some experiments for a cooling solution for my future 13900ks, but of course I don't have a 13900ks yet.

Was hoping, if anyone has access to any of the 13900 CPUs de-lidded, could you take some digital calipers and measure the thickness of the top of the IHS?

Not the height of the entire IHS, rather the thickness between the surface which the CPU die contacts to the top of the IHS which the waterblock contacts. I am wanting to know the distance between the waterblocks contact surface and the top of the die.

According to Techpowerup forum the IHS of Intel’s 11th Gen Core processors is 1.2mm thick copper with a nickel coat. Probably similar with 13th gen. I recommend sandpapering down the thin layer of the nickel coat, since the copper has a thermal conductivity of 401 W/mK while nickel has a thermal conductivity of 90.9 W/mK. Like i did for myself too on 12th gen.
