    Hello,

    I am wondering if anyone ever stressed up mbp for long period? (maybe 24h or more?).

    Actually I am currently executing my matlab code (I am a reseacher) for almost 12 hours (still running now). My mbp cpu load average is above 2, with cpu temperature around 70C (+/- 3degree).

    I am just wondering if it is ok or should I just stop the execution and run it on PC instead? I couldn't find any review whether mbp is durable enough to run 24h or more with very high cpu load.

    That's nothing.

    I usually do load average of over 4 to 5, for weeks at a time. System still kicking fine no problem. This is being done on a Core Duo from 2006.

    As long as the fans work and the system is kept within a normal temperature (under 100 deg C), it's fine.

    CPUs don't wear out. As long as the cooling system is working normally and nothing is getting excessively hot, your MBP will last a while. I would be most concerned about the battery since they don't like heat.

    Both use the same type of processor, so it would be the same as running it on your PC.

    OSX is built that you virtually will never need to shut off the computer. You are using it as designed

    It can handle it, but in general you want to avoid applying such stress on a CPU.

    CPUs do wear out just takes a while.

    while true, the OP should note that the fans and other components will die sooner than the cpu

    No. Just because two different machines have the same processor does not mean they will perform the same under load.

    That being said, the MBP will be fine.

    Folding@home + Handbrake.

    Easily put the CPU load over 5. The highest I've hit was about 7.9

    Thanks for all the responses.. I think my computation will take time about 70hours (still running now). The cpu temperature is stable around 70-73C with fan running around 5700-6000rpm (checked using istat pro). I think I have to buy cooler pad.

    I think you'll be fine and that a coolpad is an unecessary expense.

    Honestly the odd 70 hour calculation really isn't going to hurt it!
