As an additional note, if you’re comfortable doing so, I’d recommend going into the BIOS and undervolting the CPU down to 1.2 or 1.3 volts.
A common issue with the higher end Ryzen 5xxx CPUs is that they run a bit hot which prevents them from boosting clock speeds as high for as long as they’re able.
My last build very similar to yours, (3090, 5900x, 32GB RAM) and I was able to shave almost 10C off of the CPU temps by setting a CPU voltage offset of -0.15 volts.
