I'm not exactly sure. My sense of smell has been shot since I got covid. It feels so weird. Some smells don't exist, some are much stronger, some remained the same.
One good example is burning anything while cooking.
I can just feel it though. If I'm itchy while in my kitchen, 9/10 it's ants (ground floor old apartment)
It might not be a bad idea having btop with like 100ms refresh. Watch it while using it and see what the thermals are as everyone is suggesting. Or if any other cpu thing is being weird. I've had weird freezes before due to lack of power. Or being on a screwed up power plan.
Canned meats like tuna or spam (technically it's not spam as it's chicken/beef (and not branded spam)) but it's meat in a can in general. It's largely a smell issue in my house and my family hates the smell.
Unless if you have the random HP laptop where no Intel card works.
(I have this laptop, there's 2 ax200s that HP ships, one with Intel one with amd. No it's not CNVIO)
