    im using a 2010 15" MBP i5 with anti glare. I love this computer with the only downsides being heat & size/weight. Battery and hopefully a cooler lap computer with silent fan is what im hoping the 13" MBA haswell will be. What can you tell me, owners of these computers?

    Been running email, Safari, and random app installs tonight on new 13" / 128 / 8gb w/ 10.9 DP1. Seems cooler than my 2012. Fan hasn't kicked up at all and iStat shows ~1300rpm. Has been sitting on my lap the last hour or so and cool to the touch. Java installing right now and humming along.

    i7 here:

    YouTube 720p + few tabs = 46-55C no fan noise (1200rpm).

    Only time i heard the fan kicking in was while playing Diablo 3.

    Way cooler. 30 average on my 2013 11" i7/8GB/512 vs 55 average on the same 2012 configuration running the same apps. Fans average 1200 on the 2013 vs. 2000 on my 2012.

    That does sound great. IIRC, the fan speed when idle used to be 1900-2000rpm in older MBAs. Now it's just 1200 so it is even quieter!

    Does it now feature the assymetrical fan design like the rMBP??

    I had my 2011 i5 MBA sitting next to my 2013 i7 MBA while utilizing migration assitant. The 2011 fans spun up almost the whole time, but the 2013 stayed whisper quiet....

    I believe this was introduced on the 2012 Airs.

    Mine's been setting up FileVault on the SSD. The highest temp I'm registering is the Mem Bank A! sensor at 37 degrees C, the remaining sensors are in the 27-31 degree range, with the fan at 1215 RPM. Very quiet. This is a 2013 i7 MBA, maxed out 8GB RAM/512GB SSD.

    It's running cooler than my mid 2010 15" i5 MBP. On that system, the CPU and GPU are in the mid 50s with fans at 2000RPM, doing nothing but having this web page open so I can type this post.

    It looks like Apple has lower the base fan speed. In my 2010 13 MBA, the base speed is 1999rpm, looks like it's around 1200 now with the cool Haswell chip, another source of energy savings.

    Thanks for confirming, and the detailed info too.

    It's simply brilliant to see the MBA has come so far! So much cooler CPU and quieter fan noise.

    My 2012 also hovers around 2000 rpm when not doing anything special (surfing, mailing, watching movies and such), so that seems to be the old default setting. Completely silent, but still - cutting the rpm down to 1200 should indeed save a lot of power, happy to see them being able to do that.

    Every little bit helps, but it's hardly a "lot" of power. Very little actually.

    Maaan, that new MBA sure sounds like a nice machine! Now that I'm seeing the results, I have to say that Haswell delivers even more than I was hoping for.

    Do you have any numbers on this? Not that I demand proof, but I got interested in the actual savings and tried to google it, but didn't get any great results. The few hits I found indicated that the fan itself is quite the power hog, but changing the RPM from 2000 to 1200 shouldn't make a big difference, a watt or so maybe. Still counts, but less than I expected. Once we get to laptop processors that doesn't require fans, then the saving should be pretty significant - but that's still some time away :)

    No heat whatsoever, cool to the touch, considering I have watched youtube videos, while restoring my entire iTunes library from an external hard drive.. I have also watched some hulu videos. As a matter of fact, I haven't heard fan noise since I got it, makes me think I got no fan! :D

    No problem, thanks! I'm hoping the i7 is just as good with heat and battery.
