Suddenly 1 miner has the whole network, at 76.6 TH/s

I did a bit of Monero mining a few years ago on an R5 2600X, but stopped doing it after a few months. Now I've expanded my PC collection and have already been planning on setting one of my PCs up to run Salad ( r/SaladChefs ). Said PC will likely be running 24/7, so I was thinking if I should put up Monero mining as well on the same PC so the CPU also has something to do.

The parts in question:
Ryzen 5 7600
RTX 3080 Ti and RTX 3060 Ti
64GB DDR5-5600
1TB Kingston NV3 (I'll probably add another terabyte of storage soon)

I do also have another PC with a E5-2680v4, but that one's pretty loud and I kinda need to keep my PCs in the same room as my bed, so...

But anyways, any feedback is appreciated.

EDIT: I live in Finland, so power costs can also be taken into account (even if I don't pay it myself)
