MACBOOK PRO & SNOW LEOPARD - OVERHEATING

I use the same laptop as the Larry. My laptop has been screaming a lot too.. and It goes to 90 degrees centigrade while watching videos on Youtube..!! I cant believe it..!! I hate snow leopard so much..!! It drains my battery like nothin I have ever seen.

I had the same problem with overuse of memory, CPU use and temperature on my MBP5,1. In Activity Monitor there was a process something like - hdutil. Sorry, it was later in the evening and i was tired (which probably gave me the courage to do it). I force quit the process and the problem ceased. I restarted and have watched for two days. Memory and CPU use dropped to normal and the temperature decreased 50%. Your mileage may vary but it was quite dramatic for me.

Check out activity monitor and look for a process that is taking up all the room.

I do not see such an app.

my computer only get up to 90 degrees celsius (194 F) while I use some program's

dvd remaster
watching youtube (some say this is related to flash)

And that's about it.

Still no-one came up with an answer to this vital question:

WHAT TEMPERATURE IS TOO HOT?

What is a safe range? Many ppl that report here do not even report their CPU Temperature

Your T. is too hot when it gets over 105 C. when i am right.
Is this the cpu we talk about?

My two cents...
I (while very excited) upgraded my late 2008 15" MacBook Pro to Snow Leopard today and the temperature (of CPU A) immediately sky rocketed to 70 degrees C, with the fans running at 4200rpm. However my CPU is running at a fairly constant 50%.
After stumbling across this thread I removed Sophos Antivirus and turned off plug-ins & java in Safari - but to no avail. The top temp. reached was 76C while on Google in Safari - GOOGLE!
I await a resolution...

While I'm foggy on the name, there was a process chewing up lots of cycles and memory. When i quit it, the MBP's temperature dropped from ~170F to 80's. Have you checked for anything chewing up cycles?

well I can say that those are normal temperatures. As long as it stays below 105 it seems it is ok.

Anyone any other idea's? I think most people just talk about hot without knowing what is too hot. But if I am wrong I am happy if someone corrects me...

If I was bccammo I would not worry 70, 80, 90 or even 100 degrees Celsius, It seems to be within normal range.

Even though you can cook an egg on your macbook it seems to be normal

Personally I've found out that my overheating problems are caused either by "WebKitPluginHost" which is supposed to be the new Safari module for 32 bits plugins (like Flash) when Running Safari at 64 bits and "Finder".

WebKitPluginHost when it starts often uses 35-60% of CPU, depending on the job it's doing/plugin it's running, I suppose.

Finder for unknown reasons sometimes consumes 99% of CPU. Closing the Finder windows usually it stops but not always (a reboot is needed).

Maybe Apple can work on improving the efficiency of the 1st and fix the clear bugs on the 2nd. Hoping 10.6.2 will fix both of them.

I have not had any problems with SL, including 10.6.2.

Has anyone with issues tried the update?

The 10.6.2 Update is recommended for all users running Mac OS X Snow Leopard and includes general operating system fixes that enhance the stability, compatibility, and security of your Mac, including fixes for:

- an issue that might cause your system to logout unexpectedly
- a graphics distortion in Safari Top Sites
- Spotlight search results not showing Exchange contacts
- a problem that prevented authenticating as an administrative user
- issues when using NTFS and WebDAV file servers
- the reliability of menu extras
- an issue with the 4-finger swipe gesture
- an issue that causes Mail to quit unexpectedly when setting up an Exchange server
- Address Book becoming unresponsive when editing
- a problem adding images to contacts in Address Book
- an issue that prevented opening files downloaded from the Internet
- Safari plug-in reliability
- general reliability improvements for iWork, iLife, Aperture, Final Cut Studio, MobileMe, and iDisk
- an issue that caused data to be deleted when using a guest account

although i think its allready been confirmed i can say that these are the roots of my overheating problems too. So much so that i can close the process and withing seconds the computer cools 20+ degrees celcius

wow thanks i didnt realise that it was only happening with safari in 64bit mode....ill just switch it over until they fix the issue....it also now mean i can use multiclutch again with safari for now 🙂

Nah... I just tried it now. Switching to Safari 32 bits just moves the CPU usage from WebKitPluginHost directly to Safari. 117% CPU usage watching the same 540p flash video in both cases. This after having upgraded to 10.6.2. Not sure if the new OSX release introduced any improvement on this subject either. My temp on idle is stuck at 50 C like with 10.6.1.

50 C idle temp (CPU?) is completely normal - maybe better than normal, IMHO.

not when it used to be less on an os that apparently has just been optimised, its a joke.

Frankly i have gone from a stable 35˚C idle to 50˚C from just upgrading to sl.

Seriously this should be fixed when we have isolated the overheating problem in safari it should be quickly looked at. My cpu get a full load sometimes from watching a flash video...which rockets temps sometimes to 120˚C. from playing a flash video? 99% of my cpu? haha i dont think so.

Since ugrading to 10.6.2 i havent had an issue like that yet but it still reports 60-70% load when running flash players :/

anyway a resting temp of 50 is not going to hurt my pc or my cpu its the overheating that worries me as i have to leave my laptop unattended and on sometimes rendering out work if i left it and it was overheating it could shorten its life dramatically. After spending over £2000 on this laptop i wouldn't call that acceptable.
