After intall Spotlight indexes your hard drive, which will take an hour or more, depending on how many files, speed, etc. In my case the fan ran almost continuously until finished. Now no problem.
I believe the indexing process is called mdworker.

Likely a waste of time. The indexing will end, as it did for me, and so will the heat. Unnecessary SMC resets are not recommended.

My MBP late 2009 has been running hot also. Indexing was finished in about 15 min. I have 8 gig of ram. No load to 5% load on CPU results in 185 F CPU temps and 5000 RPM fan. This is with NO PROGRAMS RUNNING! I did a SMC reset, no help. I reinstalled lion, no help. When I try to do a time machine back up the temps have risen to above 200 degrees F. Not good!
I concur with the mdworker indexing as a primary cause of the heating. My new MacBook Pro did the same. For 40 minutes (400GB).
All is well now.
I'm surprised that Apple didn't slow down the indexing during the first run. This must be hitting a lot of people.
My Macbook Pro (Mid 2007) is also running fans blazing, with almost no load.
The indexing of spotlight is already done, so that's not a problem.
When I dont use the Mac the fans are almost quiet, but not like before with Snow Leopard.
As soon as i start using Safari to browse through some pages the fans start to rev up, even if there's no flash animations on the pages.
This is a pretty big issue in my opinion. There seems to be a bit of talking about it if you google it..
Hi there
Apparently this is an issue with Adobe Flash. Adobe acknowledged it earlier today and are working on a fix.
Good luck.

Oh, yeah, I forgot to mention: I also uninstalled Flash when my system was overheating during the mdworker indexing cycle. Maybe it was Flash that was causing the overheating problem. Flash and mdworker were both near the top of the list of active processes. I can live without Flash for a while.
Same Here, I have a new MBP 2011 17" with 8GB and an SSD and since I installed LION It gets really hot and fans run all the time. under Snow leopard it would be cool to the touch.
Whats the deal?

Not unusual. Someone (not me) reported 90° C using Lion (not with the released version — some time before the golden master of 10.7 was seeded). Here I sometimes see peaks above boiling point. Don't worry about it, there should be no harm to the computer.
Please add to your profile some details of your hardware.

Issues may be not limited to animations.
Try uninstalling Flash then whenever playback of Flash content is critical:
Some technical detail of what's new in Lion is alrady published:
What's New In Mac OS X: Mac OS X v10.7 Lion
For more in-depth knowledge, without paying to join a programme you can view at least some of the following:

My uneducated guess is that some of the cooling and/or load — maybe not demonstrable by Activity Monitor — is GPU-related, something to do with tightened integration between OpenCL and Grand Central Dispatch.
Incidentally I'm currently not convinced that iStat Menus 3.18 (3.18) offers a suitably comprehensive guide to the gamut of things that Apple does with 10.7 (Build 11A511).
Interesting, in the case of the opening poster I would tend to agree with the earlier comment about SMC resets.
Seeing your post in the other topic, I wonder whether there was more coincidence, than cause and effect. But I keep an open mind.
For OP:
If you have MS Office for Mac installed, please read the linked article:

Removing the MS Office Spotlight plug-in fixed it.
I had installed Office for Mac 2011 shortly after upgrading to Lion. The problem seems to be there rather than with Lion.
