I have the same problem, and deleted the
files in /Users/*/Library/Preferences folder.
My Macbook Air still has CPU temperature like 80 till 90 grades with 2000 till 5000 fan speed. But my 'Dock proces' is not high anymore. So for that part it seems to work.
But is 80/90 grades with only safari and itunes bad? A friend of mine bought the same Air as me but has like 50 grades when he's doing the same as I am.

Sometimes after I shutdown my 2012 13" Air, the Dock problem with high CPU usage returns!
I need to delete these filese again and again.
Anyone knows how to fix it?

Zalaroth, I am guessing in your case you have an application that is draining your battery. Is there no other item that is taking up high CPU usage? 80-90 degrees doesn't sound high to me. Uninstall programs you suspect and test. Good luck.

Could be SendToKindle

I just uninstalled and reinstalled SendToKindle and all is fine (for now).
If there's any change, I'll chime back in.

Deleting those files helped for me too (MacBook Air 2012 13"). Thanks.

Thank you LosiMD.
I also had Dock process gone rogue, always taking 95% of CPU usage. The fan was always at 5000-6500RPM and battery was usually drained in just 3 hours using MS WORD
After restarting the fan is now below 2000 RPM
CPU at 48c (much cooler than it ever was)
CPU usage is only 1 to 4% (before was always at 17++%)
Dock process now only takes 0.x% of CPU
I was starting to hate my super noisy 2012 MBA but now I can enjoy it in silence

worked for me.

Worked for me too, new to mac and took a while to realise i had to look in my /users/MYNAME/library/preferences folder as opposed to just /library/preferences.
Thanks to all for your help

I see you found the user preferences folder. it can be confusing having a system and user prefs folder. The good thing is that most of your settings will migrate with you when you buy your next apple computer.

i don't know if this will help everyone but i have just received my i7, 8gb, 512Gb MBA
noticed the fan was going 10 to the dozen at full speed and the battery looked like it was dropping 10% every 10 mins!!!
checked activity monitor and the cpu was 90-95% on 'Dock'
anyway, just so happened to check software updates and one of them was for the MBA after Jun 2012 and said it was a fix for the CPU running
installed, rebooted and now no noise and no fan!!!
hope it helps others (i tried dock plist delete and also the Parallels windows application trick to no avail!)

There is possibly a another problem affecting me - about every other day my 11" Macbook Air with 1.8G i7 / 256 MB spins up the fan and the CPU temp rises to 70C with only one or two percent CPU load.
Power cycling the computer clears this.
We'll see what happens - it's not normal for the CPU to get hot unless, as the articles say, the CPU is under load. Right now, under low load typing this messge, CPU temp is 48C. My OS is current as of Jun 26.

Awesome - thank yo uso much. Helped me too. Couldnt locate the "lockfile" file, so i just delete the other one.. it worked!

No duh ur getting 1.5 to 2 hours of bat life is because the "11 air is designed only for the i5 not the i7 and also u have the 512 gb which also costs a lot of heat..

For what it's worth, Growl.app was the issue that led me to this support forum. It doesn't show up in "top" but Activity Monitor.app had this to say about it: http://cl.ly/image/2k2e3Z072V0F
