It's simply an unknown right now how stable Raptor Lake is, or even if it will be able to perform at the same level post-patch. The i5 you got will run cooler, so you might be fine: but fundamentally, recent Intel CPUs have faulty circuits and bad design in them that you have to work around and be aware of. Keep the packaging and be ready to take advantage of the extended warranty Intel put out if your chip goes bad.
EDIT: Also invest in a beefy CPU cooler and maybe even reapply thermal paste every now and then, it will be the difference between life and death for gen 14 systems
