Question Will running my CPU at 70% - 80% usage reduce effective use lifespan?

[Gamefreaknet]

I have recently gotten into stuff like Crypto and decided that I will use both my Laptops for mining however whilst my first laptop is fine as I can use its dedicated GPU (RTX 2070 Max-Q) I am running on my other laptop a mining software which uses the CPU for mining Crypto instead.
The laptop using the CPU mining software (which I am constantly keeping running) however runs idly at around 75% - 85% usage constantly:
CPU: i5 1035G1 (Turbo Clock - 3.6Ghz | Base Clock 1.2Ghz | Cores - 4 | Logical Processors - 8 |)
As far as I can tell it isn't having any thermal issues as it flatlines between 75% - 85% usage (with vary rare spikes up to around 90% - 95%) and it runs at an average clock of 2.3Ghz - 2.5Ghz consistently however will this high usage stress the CPU causing it to wear down faster?

Its not usage percentage. Heat is the potential issue.

But, if your mining is actually profitable, you buy a new system when this one dies.
It is a consumable part of the enterprise.

Heat and voltage are potential CPU killers. Keep them at reasonable levels and it will work forever.

... CPU causing it to wear down faster?

All semiconductors degrade at some rate no matter how hard they're being used so running it constantly will definitely cause it to "wear down" faster. The rate of degradation at depends on operating temperature: higher temperature degrading faster.

I agree keeping temperature in check will help immensely but it will still wear out faster than normal useage patterns simply because it's operating constantly, 24/7, while mining. If kept close to normal temps it should still have a long life, almost certainly longer than it's usefulness (manufacturing defects aside) but that would probably mean lower hash rates.

Yes but it's counted in years, many years.
