I do a lot of statistical analysis in R (which uses a lot of CPU and RAM). Whenever I run my analysis, my laptop's fan runs at top speed. Monitoring tool shows that 1 of my cores runs at 100%, the rest normal (R doesn't use multi-core by default).
Whenever I do my work I feel instinctively worried about my machine, and I want to ask whether this instinct is actually validated?
My instinct could be wrong because:
Using CPU a lot does not wear it down
Computer fails much more often because of other components
CPU may be worn down, but takes a long time
