    Just like the title says. My 15" i7 2010 MBP is consistently running hot after installing Lion. The CPU and hd aren't being thrashed, so I'm not exactly sure what the issue is.

    Any ideas?

    It's because lion is indexing your mbp. It can take up to an hour, so don't worry. After it is done it'll go back to normal temps. click on the little magnifying glass at the top right and it'll shop the progress.

    Nope, it's not that. The indexing was done a few hours ago when I'd first installed lion.

    I've heard restarting the machine may help, but you've probably tried that, yeah?

    Yep. As I keep using it though it seems to be rectifying itself. After a couple of restarts it's been getting better each time. Odd...

    Having this same problem myself on my 2009 MBP. Lion is running a good 15-20 degrees Fahrenheit higher than Snow Leopard ever did. I've restarted twice in the 24 hours since installing Lion, but not much has changed as of yet...

    Mine seems to be running fine now. Try going through all your apps and updating each one, and quit processes that thrash your CPU and HD. Is your MBP still indexing by any chance? If it is, then that is most likely the cause.

    Not near my Mac right now, but it's definitely done indexing, I checked for that earlier this morning. I'll update all my apps later tonight, and report back if there's any improvement.

    Honestly, I thought part of the issue was the new update to Safari, since there's two separate processes now for that application. That and kernel_task eating a high (300-400) amount of RAM.

    Maybe it's not the MBP that's getting hot while watching the web shows...? :p

    My 2009 17'' macbook pro i really heating things up after upgrading to Lion.
    Indexing is all done and no cpu intensive tasks are running, just typing this, temperature is about 60 C (140 F).

    If i open Lightroom and import say 250 images and then render 1:1 previews the temperature will rise to 105-110 C (221-230 F) and stay there until the rendering is done (10-15 min). Fans spin at 5700 rpm.

    I hav never seen this before with snow leopard where temperatures stayed around 90 C no matter what.

    I'm really thinking about reverting back.

    I'm getting the same issues as well. On SL, it would stay relatively cool (about 40-45C) with integrated graphics on my 2011 15" MBP but since I updated to Lion, it's constantly in 65-75C and spiking as high as 92C. Thinking of doing a clean install because I had also killed my friend's WiFi network when joining. Might wait it out for 10.7.1, though. Too many choices. Plus reinstalling is a pain.

    I have a mid-2009 15" as well and it ran hot (90-100C) for a while after upgrading to lion as well and then spontaneously returned to normal. I'm pretty sure it was just indexing. I really wouldn't worry about it unless its shutting itself off.

    It's not indexing or doing anything else that i can see in the activity monitor.
    Maby clean install will fix it but then again snow leopard was not so bad.

    I'm having the same issue - I installed Lion yesterday and have had consistently hotter temps and higher fan speeds since. There aren't any consistant processes causing a problem, so I can't account for it. There does seem to be more disk activity than usual (i run istat menus), but indexing is done.

    For instance right now I'm sitting here with 4 programs open - maybe 10 tabs in Chrome, an email client, a word processor, and activity monitor. The fan is very audible, by disk activity keeps spiking, though CPU activity is very low. The bar above the keyboard is veerrrrryyyy hot to the touch.

    same here. It stays cool until i run a youtube movie. I was fine all day pretty much yesterday but when i started looking at ipad reviews on youtube, after 10-15 minutes of watching those it was getting HOT.

    I tend to think it's flash.

    I've seen no temperature increase or decrease using Snow Leopard or Lion. Both have been quite consistent with me.

    You are not supposed to use macbook on your lap !!

    My Macbook pro goes up to 80 C' degree with safari + Word.
    Is it a normal temperature ?
    I went to Genius Bar saying It is too hot and I can't put it on my lap.
    Can you guess what they said ?
    Genius : " Macbook Pro is not a laptop. It is a portable computer. So, you are not supposed to use it on your lap "

    OMG !! In apple homepage, You can see the picture people using macbook pro on her lap. !!

    Has it been cleaned from dust yet?
    Is Safari using flash?

    And pictures don't matter.

    Seriously just had a good laugh over this. Mainly because my friend, an Apple Genius bar guy, told me the exact same thing. And said they are trained to say those exact words

    Ive also noticed a slight increase in temp, with Lion, on my 2011 15" MBP. But it's only unbearable when using PhotoShop.
