fan running continually & heat

My Mac Book Air fan seems to run all the time now - it never use to. Also noticed the base/bottom of lap top seems warmer than usual.

Today, when I detached from power cable & used lap top on battery, the battery life was very short.

Recent history: I took lap top last week to local authorized Mac service compamy & they diagnosed corruped OS volume causing the system to slow down. This was flagged by Apple storage diagnostic during testing. They copied my data, erased internal drive, reinstalled OS X & migrated data back. Afterwards, I noticed the fan running, took it back, but no problem was found.

Any thoughts on fan running continually & the "extra" heat at computer base?

I'm still under Applecare. Should I take it into Apple or is there something I can do?

Thanks.

MacBook Air, Mac OS X (10.7.5)

Great info, thanks. Learned quite a bit.

Since no application showed a high % of CPU (the highest was something called bash at 15%), I'm wondering if an application I installed a month ago, Quark which is over 1 GB and not open, could that cause the fan activity?

Update related solution: When I followed your suggestion above & clicked on the Activity Monitor link, I learned about "bash" & then read posts discussing my same problem--increased heat & fan activity & shorten battery life.

So I uninstalled my Kindle app (maybe it was called Send to Kindle) but nontheless my fan became silent. Yeah!

Now to see if my battery life is extended.

Many thanks for your help.

You are welcome. If the fan has quieted and slowed, most likely your battery life will improve.

Thank you for the helpful link, stedman1! In Acitivity Monitor, I found Adobe Flash was taking 100% of my CPU! The fan noise is gradually diminishing and the heat's dissipating.

My MacBook Air fan has run constantly since I have owned it. I don't have anything that is using the CPU % too heavily. I can not figure out what is causing it to run and run and run. I have taken it to the Apple store several times but they always say nothing is wrong with it. How do you argue with that? It's like they either believe you or they don't believe you. They tend to think you are making things up? Anyway, my fan is running vigorously now (as always). Oh, Apple did replace the fan once and the bottom protection place (the back). This did not fix the issue.

Checked my CPU and found that one of the HP printer drivers process went off the roof. Uninstalled the drivers and quit this process - my fans stopped and computer cooled down within a minute.
