Fanless Mode (Extreme Power Limiting)

[tlefko]

We can further modify the clock speeds and such by modifying the power limits. Theoretically, this would improve battery life by exponential margins. However, this would have an even greater hit on performance. As in internet machine, consuming media, emails, documents, etc. This is a fantastic option to consider (my personal choice). However, the power configuration within the kexts and SSDTs, in conjunction with voltage shift preferences set this up in the most performance efficient way possible. On tasks not requiring full utilitization of all CPU cores, the PKG power is allowed to giving the maximum frequency possible. This greatly reduces the performance hit from single core applications despite the limited PKG power. Multicore tasks will always scale to the highest freq. possible

This also makes the PC essentially fanless, due to the lower power consumption thermals do not rise. The battery life running like this is absurd.

Again, in daily use performance is excellent. I use the PC primarily for media consumption, research, documents, etc.
