If you're hardline-ing on Ivy, delid the chip, then you can push 4.8ghz easily. Get 2x8gb 2400mhz ram because ivy can support it.
Get liquid metal for between the die and IHS. Regular paste between the ihs and heatsink
You don't need a new heatsink, you can get away with a cheap single tower after delid it will be fine.
Tune fan curve with "Fan Control" app, great app.
Ivy is good for everything outside of pr0-g4m3r 600fps, and the modern games that are really badly designed that chews up cpu, helldivers, halo infinite.
But without 4.8ghz, it's going to struggle, both on memory bandwidth and raw ipc.
Tp4 WOULD HESITATE to rescue an IVY, because with all the parts involved, You can buy, as difficult and unattractive a proposition, an AM4 build. Used 5700x can go for decent cheap.
Of course TP4 is highly AGAINST AM4, You should spend $1500 to get an AM5, amd 7700 (nonx, refurb cpu, $160)+9070xt build.
