MBP running hot (not a WoW question this time)

[Kristenn]

Yeah I quit playing WoW. Anyway, to the point. I'm running my 15 inch MBP (late 08 model)

2.53 Ghz Core 2 Duo
4 GB DDR3 RAM
Nvidia Geforce 9400M (600M, whatever)
Nvidia Geforce 9600M GT (512 MB)
250 GB 7200 rpm HDD

On the dedicated graphics. Its plugged in. I noticed it running hot when using flash in Safari (big surprise, right?) and thought it was because of flash. So after I was done (wasn't using flash anymore) I started safari later and was viewing text documents online and my fans... I can actually hear them and the top left part above my keyboard is hot.

Also I checked the activity monitor and there is a thing called Kernel_Task (probably supposed to be there, its intel and it sounds like it should be there... lol) using 256 MB of RAM and 1.4 % of processor and like 75 threads.

Anyway, Pic below of iStat Pro.

Running hot. Anyway, even when I was just using Safari to browse the website (nothing running in the background besides Mail) it keeps getting hot and I can hear the fans at almost always 3000 rpms.

I don't recall it running hot for simple stuff like this before even on the dedicated card. Just wondering should I worry about it? What do you think is up?

Thanks! ^^

CPU is working quite hard for kind of load you are putting on it (Safari+Mail).
The total CPU load is 41%. That would probably explain your temps and fans.
What could be using all the CPU?
Was there a lot of Flash on the sites you were viewing? (Flash is a CPU hog)
Were there any other tasks running?
- in Activity Monitor, you can select "all processes" rather than just "my processes" so you can see what the system is doing as well
- in Activity Monitor, you can sort by CPU load and check out the largest

SOMETHING is using 33% of your CPUs - I bet it's Safari+Flash

If so ways to fix it include
- download ClickToFlash which blocks Flash
- download Flash 10.1 beta which uses about 1/2 the CPU of Flash 9

best of luck

Wow really? I have the 2.4 MacBook Pro (late 08 as well) and I have it set up to constantly run at 4000rpm. Maybe your fan is going too low? Anyway, maybe showing a screenshot of your processes would help a bit.

Hmm. Well thanks for the replies! I did update flash. And I restarted the computer today. I'm not on the dedicated card though but it seems to be running cooler again. =/

Fan running all the time

I'm new to this site and I just wanted to ask a question, hope, I'm not intruding posting it here.

Suddenly my macbook fan started running constantly, when I looked into my activity monitor I found a driver to my lexmark printer was using 100% CPU. I have had this printer and used this printer for months and I cannot figure out why this suddenly happened. I quit the application and now my computer is cooled down, no fan running. Since I am going to college I use my printer quite often, does anyone know what I can do to solve this problem?
Thanks so much!!
