If it throttles CPU it means by definition means that a fan helps. Also constant heat increases failure rate.

- parineum 4mo agoCycles of heating and cooling are what increases failure rates. The thermal expansion and contraction causes issues.
- ssl-3 4mo agoThat's one way to put it. Another way is that my great grandchildren won't care about inheriting my collection of hobbyist SBCs, and therefore nor should I.
- rjzzleep 4mo agoPermanent heat doesn't?
- magicalhippo 4mo agoFrom what I've gathered, heat absolutely does[1] affect[2] it[3]: Subsequently, in 1967, Black of Motorola experimentally derived a median time to failure (MTTF, i.e., operational lifetime) model for EM in Al interconnects, showing that the time to failure due to EM is inversely proportional to both the current density and the absolute temperature of the interconnect.

- numpad0 4mo agoThermal cycles, heat, current, all contribute to degradations and failures. It just so happens that cycling is the worst and everyone knows "it's the power cycles that kills computers". Doesn't mean at all that electronics can't be damaged countless other ways.
