Is this because the fan isn't used as much? I generally assume that anything involving moving parts uses lots of energy, comparatively speaking.

- mrtksn 4y agoThe laptop that used to last 6 hours when watching videos now lasts about 8. The fans were not spinning up to full blast at that use case bore the mod too, so I don't know how much the fans are responsible for the difference. My speculation is that the CPU is using less power when cooler due to the relationship between temperature and conductivity.
- smoldesu 4y agoCPU stays cooler for longer -> Processes throttle less -> Processes finish faster -> CPU can return to idle state faster This is particularly noticeable in burst-y workloads like web browsing or software development.
