> FWIW, my water cooled AMD Ryzen also shoots up to very high temperatures immediately when loaded. It can touch 80C like a lightswitch. It might be interesting to look into a block which covers the chiplets more. Mine does max 55 at normal speeds and PBO max/unlimited power it does about 70C max (and about 220W draw for a 5900X). I have no peaks like you describe. That used to be a bit more with my old water block which had copper on the chiplets but no water channels.
