The current Air might as well be fanless. The fan is nowhere near the heatsink on the CPU, once it finally kicks in it only pushes the air through the case, its impact on the CPU temperatures is minimal.
Yep. The only saving grace is that it takes a loong time for the fan to finally kick in, it's pretty much impossible to make it run with anything less than 100% CPU load, and even then it takes a few minutes to kick in.
