My 2010 MBP is running hotter in Lion as well.
I had Chrome and Photoshop open, and the fans were running at 3000rpm but I could barely hear them?
Now with just Chrome open, they're back down to around 2000rpm (which they normally ran at with SL) but my CPU is around 60 degrees C and feels super hot at the back. It was never that hot with SL just browsing the web.
I don't think my fans are kicking in as much as they should be.
I think chrome is all screwy in lion. I switched back to lion and got the omnibar plugin. I think its works better than chrome, as of now, in lion. In a couple/few weeks, once it's optimized i'll try it out again.
I think I'll just live with it for now, because I use Chrome for everything. I don't want to spend the time to switch. I only use the other browsers for website testing.
It wasn't this hot earlier today though, so I don't know if it was maybe Photoshop that made it get hot? But if that's the case, I would think the fans would pick up more. I can't hear them any more at 3000rpm than 2000rpm.
I used Chrome all the time because Safari wasn't up for it. But the new Safari in Lion resolved all my issues and I find really gotten much faster, and way more powerful for reading with the Reader option and full screen view. Since Chrome is based on Safari it should have been more able to take advantage of it's technology all along... only annoyance left for me is that they still haven't integrated the search into the one address bar.
Any how, I've been able to brows activly now for five hours straight with both fans set to 2000 RPM and not breaking 50°C. Granted I'm using HTML5 as much as possible in favor of flash plugins. Still something I can't manage to do browsing in Chrome!
Found the plugin literally seconds after posting that messageI feel complete... like a pig in *****
lol. I felt the same way. I can't figure out why safari didn't just do the same thing. SO much easier.
