Because most people want laptops that run cooler than 80 degrees most of the time on their laps. I would rather have a fan that runs a bit, ideally the ability to control the fan in exchange for lower CPU and system temperatures; after awhile, the temps will reduce the MTBF of the overall system. This is the same thing that people complained about in what they thought they saw in the T43; "Heat! Fan! WAH!"filter wrote:Well it seems these things CAN happen with a MB or MBPro. My MBPro CPU Core temp reached up to 80 degrees while under full load. Its not bad at all. The outside casing is very warm but not what I'd call hot. The heat issues also seem to be resolved in the newer models. Some people report temperatures similar to T60.
However they are really really freaking quiet compared to any other Laptop. Why oh why can't I have a T60 with the noise of a MBPro? Anyone know at what intervals the Fan of the T60 would kick in if I'd keep it about 70 degrees idle (at GPU)?
Maybe I'll just go for a Sony...
Further, since it uses the same Intel chipset that other laptops have used without such heat issues (the T60 being one of them), one should expect similar behavior out of it and not large fluctuations.
Also, my friend appears to have found a little bug with the MacBook Pro. If you take the battery out and power it only with AC mains, both cores peg to 1GHz and don't budge. On either Battery+AC or AC alone, the scaling works just fine. It seems to be related to the SMC.
