> To increase the number of machines under power constraints, data center operators usually cap power use per machine. However, this can cause motherboards to degrade more quickly.
Can anyone elaborate on this point? This is counter to my intuition (and in fact, what I saw upon a cursory search), which is that power capping should prolong the useful lifetime of various components.
The only search results I found that claimed otherwise were indicating that if you're running into thermal throttling, then higher operating temperatures can cause components (e.g. capacitors) to degrade faster. But that's expressly not the case in the article, which looked at various temperature sensors.
