Hey everyone, I have a macbook pro, early 2008 model 15 inch, 4gb ram, 320gb hard drive.
Since installing SNOW LEOPARD, my machine is now overheating.

This was an issue I believe with the previous version of Leopard, but a patch was made by apple, and the overheating issue was fixed. But I'm guessing they may have forgotten about this particular problem with the new OS.

Does anybody know anything about this or having the same problem ????

MBP 2.4, Mac OS X (10.6), overheating

    I'm not sure what you mean by over heating but since going to SL my MBP is running hot at times. For example right now I have only itunes and firefox running and my cpu temp is at 70 degrees and the fans are running at ~3200 rpm.
    According to Activity monitor my cpu usage is about 10% (4% user, 6% system)

    It happens when I'm not doing anything as well, e.g. the other day I turned my MBP on and logged into my account, didn't open any programs just logged in. Came back about half an hour later and it was running hot. CPU temp in the high 60's and running at over 3200 rpm and the casing just above the esc key very hot to the touch.

    So it's not just you and I would also like to know if this is normal or is there a fix for this?
    I have a 15inch MacBook Pro 5,1 2.66Ghz 4Gb RAM.

    I've got the late-'08 MBP with the same configuration and haven't noticed any big difference between Leopard and Snow Leopard with regard to fan speeds. I should note though that I use Fan Control which continues to work OK with Snow Leopard as long as you are using SL in the 32-bit mode.

    I've got a 2008 Macbook. Since Snow Leopard was installed, the disk (or the fan) has not stopped working and the unit temperature is noticeably higher. I thought I was the only one. How do I get my machine back to "normal" operation? Is their a fix?

    I am having the same issue with my macbook and imac since upgrading to 10.6, particularly when running iTunes.

    The same thing is happening to my MacBook Pro 2,2 that I bought in the spring of 2007. Since upgrading to Snow Leopard, my fan regularly comes on, even when the Activity Monitor show relatively low activity.

    I'm experiencing the same with regards to overheating since the Snow Leopard update. I've downloaded, installed, and restarted with the 10.6.1 update as well. I also have an MBP from Spring 2008.

    Before the upgrade, the fans will start to get noisy and the temperatures will escalate when CPU usage is over 40% or so. However, with Snow Leopard, the computer gets really hot when CPU usage is in the teens. This is doing things like watching a movie or downloading large files, the computer overheats very quickly.

    I'm hoping that Apple's engineers will issue a patch to regulate the temps in a future update.

    Same here.......low 70's, 4000rpm, CPU usage in the 30% range, with Finder using most of it!

    Same here as well. MacBook 2,1, just running Safari and Entourage. Often the temp goes above 70 C and the fan starts spinning like crazy, even if the CPU utilization is low. I installed Fan Control, no changes. With Leopard I didn't have this problem.

    I have a MacBook Pro 2.16 from Late 2006 with the same problem. The CPU A temp is over 70C and the fan runs most of the time. It never went or 65C with Leopard and the fan only ran constantly in early versions. Later versions of Leopard fixed that.

    Just want to register my complaint as well. Mine not only runs hotter but the battery depletes quicker as well.

    Just adding my small voice — and very hot computer with an always running fan — to the list of frustrated users. Slow and hot has been my experience since upgrading to "SNOW" Leopard. I could use some snow right now to cool it off.
  • Pinky Willis Level 1 (0 points)
    Me too! I have upgraded from Leopard to Snow, and have noticed the fans running more often, and Gameplay on Call of Duty 4 is becoming very jittery withing 10 mins of playing from excessive CPU/GPU heat with snow leopard. With leopard it just worked without a problem.

    Fans running constantly at 6000 RPM without any program running - - just letting it idle or running solely itunes. Iphoto 09 unusable - - when you edit in full screen - - the screen shows colored artifacts all over. Internet has been very spotty and misbehaves. I have tried every solution - - even spoke with apple tech support. This has been a nightmare. No soloution?! Really hesitant to take it to apple store, but seems like I have no choice.

    My late 2008 unibody macbook pro has the same issue. For a while, 10.6.1 seemed to have fixed it, but now my fans never run (faster, only 2000rpm all the time)! Even if CPU temperature goes to 70C.

    One thing I noticed is that using the ethernet port has a negative effect. If I use wireless then my idle CPU temp. is 45-50C. With ethernet cable it's 60-65C. Even if I later pull the ethernet cable out, it remains high.
