No it isn't, the manufacturer literally says it's normal! I think people who spend as much money on cooling setups as the chip are the insane ones.
My favorite story: I once put Linux on a big machine that had been running windows, and discovered dmesg was full of thermal throttling alerts. Turns out, the heatsink was not in contact with the CPU die because it had a nub that needed to occupy the same space as a little capacitor.
I'd been using that machine to play X-plane for over two years, and I never noticed. It was not meaningfully slower: the throttling events would only happen every ten or so seconds. I'm still using it today, although with the heatsink fixed :)
I have a garage machine with a ca. 2014 Haswell that's been running full tilt at 90C+ for a good bit of its life. It just won't die.

- jcalvinowens 3y agoAlas, nothing that interesting. It mined bitcoin for awhile, back when it was feasible to make practically useful quantities of it that way. Never profitably obviously. Right now, I use it as a 200W space heater I can turn off and on via SSH, just running busyloops. It works well enough for a single car garage in California.
