    Hello all.

    I used to think these things didn't happen when using a Mac, but it really bothers me when I want to scroll up or down a page and weird things happen.

    It doesn't happen all the times, but most of the times it does.

    Look at the images and you'll see what happens to my computer. There are basically two things that happen. Again, see the images.

    It's not a problem of the program I'm using, since it happens with every single program (including Safari).

    What's going on?? Does anyone else have the same problem??

    I have that same problem but only in Safari... I haven't experienced it in Firefox or any other programs. I just have the problem shown in the photo on the right.

    graphics card overheating?

    Install istat and see if your really burning up.

    I don't think so, temperatures look normal and when that happens all I have to do is reboot...

    Anyway, I have iStat Pro installed, but I have two questions:

    which one is the graphics card temperature?? I mean, which one is the graphics card in the list of temperatures??

    what is the range of normal temperatures??

    The ones with GPU in them.
    I just woke my MBP this morning, and they are within a few minutes at 113F for the Diode, and 104F for the heatsink.

    I have no idea what the max for these would be though.

    I installed the fan control pref pane so I could kick up my fans faster than the OS does. I do not always work in an environment that is ~70F all the time. Sometimes I need to use my laptop when its +90F for prolonged periods of time. It sucks (I hate the heat) but I did not want my MBP shutting down, or failing prematurely.

    I found a thread here on temps, and there was one person that said he had temps for the GPU in excess of 140F.

    OK, so I just woke my MBP right now and after a few minutes the temperatures are 140F for the Diode and 124F for the Heatsink...

    I'm not gaming or anything, I'm just surfing the web...

    I don't know it that's too hot, so please, if someone knows, please let me know...

    Just as a reference, I've got a Penryn MBP... thanks!

    I have been surfing for the last hour, downloading some new songs via itunes, and checking email.

    My fans are at 2400rpm, because of fan control.

    CPU 117F
    GPU Diode 128F
    GPU heatsink 113F

    This is while on my lap, and my shorts seem to block the vents a bit.

    I think your a bit warm. Mine is normal for what I am doing.

    Try fan control pref pane, and kick up the fans a bit, see if your problem goes away.

    If you do get the program, my settings are:
    base speed: 2000rpm
    lower threshold 109F
    upper threshold 158F

    Actually, after a few hours of using it for simple tasks (Word, internet, chat, etc), here are my temperatures:

    CPU A: 142º
    GPU Diode: 160º
    GPU Heatsink: 140º
    Heatsink A: 140º
    Heatsink B: 122º
    Enclosure Base: 101º
    Mem Controller: 124º
    Airport Card: 122º

    All temperatures in ºF.

    Are they normal??? I'm starting to feel they're a little too high... It's a penryn MBP....

    Thanks for the answer!

    OK, great! thanks a lot!!

    I started with one problem and ended up fixing what appears to be another problem LOL... I've installed Fan Control and I'm pretty sure it'll let me lower my temps...

    Thanks again.

    Yeap, that appears to be just right... It looks exactly like the problem I'm having... Let's hope the update will fix it...
