    Hi everyone,

    So, I only started noticing my fan running a bit on the fast side this evening after installing the new Safari 4.0.5 update. I looked at iStat Menus for temp and CPU. And I was seeing about 190 degrees F for CPU temp with lid closed running ext display. Also there was a constant usage of the cpu (about 30% User and 20% System). There's not one particular process I can see in Activity Monitor that acting out of the ordinary and using a lot of CPU. Just stuff like coreservicesd, WindowServer, launchd that are shuffling around and using about 1-4% of CPU.

    I ran repair disk permissions and verify disk. Verify Disk found errors and said I need to repair my Macintosh HD, which I have now done successfully.

    Nothing has seemed to fix the problem. I'm looking through the System log in Console, but I'm not really sure what to look for. Nothing it constantly repeating or saying it keeps crashing etc.

    Now with the lid open, on ext display and on a laptop stand, the temps are still around the 170 F mark.

    What could be going on?

    When you're in Activity Monitor, you need to change the dropdown list in the top right from "My Processes" to "All Processes."

    After you do that, you should be able to see the process that's wasting your CPU cycles.

    I've done that. I always keep it on All Processes. The main processes using CPU are coreservicesd and launchd, which stay around the 3-3.7% CPU, WindowServer and SystemUIserver follow next in the 1 to 2ish % range.

    Nothing is crazy high percentage. Which is really confusing.

    I don't think it's something like dust clogging the vent, since I can see inside the vent and nothing seems to be blocked. Also it seems odd that the fan problem would just popup in the middle of the day due to dust.

    Here is a screenshot of my Activity Monitor. Can anyone point out anything in particular?
