[QUOTE="pigoo3, post: 1536807, member: 56379"] Gonna throw in another 2 cents regarding temps & SMCfancontrol. The fans on Apple notebooks seem to have roughly 3 speeds (at least these are the 3 speeds I typically see when I check): - ~1600rpm (fan(s) are silent) - ~4400rpm (you can hear the fans) - ~6000rpm+ (fan(s) are screaming) If a laptop computer is running at 90°C (for example)...the computers fan/fans will already be at maximum rpm. So SMCfancontrol will be of no help. If the computer is running at a lower temp (let's say 70°C)...and if the fan rpm is at 4400rpm...using SMCFancontrol to increase the fan speed may help cool things a bit. But...if the computer NEEDED to run cooler than 70°C...then the fan speed would be maxed out at 6000+rpm already (but it's not). Which is how Apple designed it.:) - Nick [/QUOTE]
