The processor on the MBA is rated at 20W versus 35W or so for the Santa Rosas. They should be a lot quieter than the Macbook. Given the notes on the forums I think that most are quiet and the few that are not have some sort of actual defect (insufficient thernal paste?) in the individual manufacturing.

BTW my understanding is that the Penryn chips are still at 35W. Intel says they are "cooler and more energy efficient" but watts are watts. I don't see how the refreshed macbooks will be any cooler/quieter than the current versions.

Yes, you are correct about the wattage but there are 2 constants within the macbook and macbook air. They both use the x3100 graphics and both cpus use the same core architecture. Now I believe its those 2 factors. I think the x3100 gets very hot, more so than the 945 chip did and that the core 2 duo core has a tendency to JUMP from cool to hot instantly when utilized. The Pentium M never did that and neither did the core duo which is a dual Pentium M. I think the core 2 duo 65nm on the santa rosa platform is just not efficient at all. I would say it has to do with the 800mhz bus but who knows. The result is the cpu goes very hot when minor things are done on the computer and it causes the fans to spin up very high.

If you fans are not over 6200rpm then you are just ad idle. Watch youtube or run spotlight indexer, it will go nuts. Or at least my macbooks did.

OK, so I have my MBA for 3 days now and my fan is constantly running at 6192 rpm. That is definitely not normal but my processor never goes above 50 degrees. Although the noise is not extremely loud, it is a bit annoying especially when other MBA are averaging les than half if not more than half my speed.. I called Apples phone tech support and they walked be through the power management reset by holding shift+option+control+power Button but that did nothing. I then followed a few other guided steps but same thing still at 6200 rpm no matter the power setting selected. only 3.2% on the cpu load. So what gives. I surely didn't drop over 3k to get a great notebook with a hardware flaw.

Ok, so now I am escalated to a level 2 hardware specialist and I get asked a few questions about the issue and run through one or two steps I no longer recall. In the end the solution to get this repaired is to take it to the Apple store and request a DOA exchange. Seeing how the stock levels at the stores is always at a minimal, I went down there anyway and as expected, no stock.

So after escalating the issue with the manager and presenting the Phone support case #, I now have a reservation for a the first Macbook Air they receive in their next shipment.

High spinning fans are not normal and I guess I would advise anyone who is having the problem pursue something becasue it is your money and you should get your moneys worth. Unless you don't care ingore what I say and be happy with your fast spinning fan.
