    Hello everyone,

    I was wondering if there are any ways to lower system temperature on MBP? My machine gets hot (particular the left side) even though I am just doing simple tasks like surfing and word processing.

    thank you,
    Josh

    Turn the a/c on. Make it cooler in your room.

    LOL.

    It is a known issue. IMO it isn't huge issue though, since your laptop still works. If you see smoke rising, then maybe pick up the phone.

    Get the Cool Feet, the little suction feet. I love mine, my MBP used to run around 70* on average, now it sits at 45* all day...every day.

    best $6 i ever spent.

    Are you using the 9600 or 9400 GPU (if you have the $1999 15" model an up)? The 9600 will get hotter. In System Preferences, go to the energy settings and turn it to "better battery life" (I think it's called, not on my machine ATM) and log off and back on, it will use the 9400m.

    We have had our 15 in unibody macbook pro for about a year now, and the heat problem has been increasing (and possibly slowing performance). We have two cats, and I believe the heatsink may be clogged with dust and stray fuzz. Does anyone know if the heatsink is easily accessible for cleaning without potentially voiding the warranty? I want to be sure I wouldn't break any seals with the processor or other components. Thanks.

    Hello,

    You could increase the fan speed to decrease the system temperature. smcFanControl 2.2.2 allows you to do just that. You can preset as many fan speeds as you like, to any value between 1800RPM (default fan speed) and 6200RPM (maximum speed).

    My Macbook stays cool when doing tasks like surfing the net and word processing etc. However, it can get quite toasty when watching videos, so for that, I use smcFanControl to set the fan speed to 3000RPM or 4000RPM, which is fast enough to improve cooling without increasing the fan noise to an uncomfortable level.
