My current build is a socket 4 system, previously with a 3800X in it, with a corsair H80i v2 which is about 5 years old now. Its in an Antec p180 full tower case. Once upon a time state of the art... now, not so much. Anyway i fancied an upgrade and am too lazy to replace the MB, but could not get hold of a 5800X3D for sensible price, and could not take the reduction in clock speed of a 5700X3D (I know, I know 
) so i went for a 5900X for 200 quid. Same 105W TDP.
Temps before with the 3800x were about 50 - 70C, now with the 5900X its 60-90C. 75-80 when normal gaming, but prime95 for 10 mins and its hitting 90 and presumably throttling. I've applied a manual Curve Optimiser value of -10 to all cores (bloody auto thing said -30 to all and wouldn't boot!). Anyway I assume those temps are not normal and that old H80i just isn't cutting it, or its lost some coolant or somehow got worse over that last 5 years or when i did the CPU swap - is that possible/probable?
Cooling otherwise is pretty good, 2 filtered intakes at the front (one pushing air over the GPU), h80i rad with 2 fans intake on the back, and top fan pulling out, PSU has its own chamber.
I'm thinking about buying a peerless assassin or similar air cooler and seeing how that goes, but I think that would mean changing the cooler backplane and therefore removing the case from the MB - there is no cutout for access to the back of the MB in that old case. If I have to do that, then i might as well just upgrade everything. In fact, i might as well buy a whole new system in a new case, except that I'd want to reuse my RTX4080 which i was hoping should last a good 3 years at least. Anyone able to confirm the backplate change would be needed?
Or I just live with it till summer when it will doubtless overheat and buy a new system then

Package temp gets to nearly 91... I know AMD say these chips can run 80-90 without problems, but it just feels far to hot to me. OTOH, it is a stress test, its not often i'm going to want all 12 cores running flat out for 10 mins.
