    Are these DELL XPS 15 temperatures normal?

    Hi,

    I am new to the forum, so please tell me if I have done something wrong, don't get angry please.

    Ok, I have a 3 month or so old Dell XPS 15 with this setup:

    - Intel Core i7 740QM
    - 2GB Nvidia GT435m
    - 640GB HDD

    I have been pretty worried about the temperatures I have, especially with the GPU and CPU after playing games. I record my temps with GPU-Z and Core Temp.

    I would like to add that I have 'invested' money in a cooling pad. I bought the Targus Chillmat, and the decrease in 2 - 5 Celcius is minimal but I suppose everything counts.

    Here are my temps:

    Idle
    CPU: Max - 48C Min - 41C Ave - 43C
    GPU: Max - 53C Min - 46C Ave - 48C

    Internet Browsing, youtube (like now) etc.
    CPU: Max - 65C Min - 53C Ave - 56C
    GPU: Max - 63C Min - 55C Ave -57C

    Playing games (such as Just Cause 2, COD 4)
    CPU: Max - 83C Min - 68C Ave - 79C
    GPU: Max - 96C Min - 75C Ave - 89C

    Note:
    - These temps are when my radiators were on and after a couple hours of playing. If I play games for only 1 hour, temperatures of the GPU never exceed 90C and the CPU never goes above 80C.
    - Generally when I keep my windows open, radiators off, the temperatures are about 5 - 10 C lower.
    - The CPU temp is the highest temp recorded accross all four cores.

    Hopefully i'll upload some more temps if I play some games within the next couple of days.

    Anyway, for anyone out there with a DELL XPS 15 or with some knowledge, please help me.

    Are these temperatures normal? I plan to repaste the CPU and GPU after the warranty runs out. Also, I regularly vacuum the laptop via the exhaust fan in an attempt to get rid of some dust, not sure if that works though.

    The T.J.Max for the CPU is apparently 100C according to CoreTemp. Does anyone know the T.J.MAX for the GPU? Apparently they can withstand 110C? Is that correct?
    Also, is the T.J.MAX the temperature where it will switch off? Or where damage starts to happen?

    In the long term, will these temperatures shorten the life of my computer? This involves me playing about 10 hours of games a week...about 1 hour on week days and 2 hours on weekends at the most.

    I would really appreciate some answers if possilbe, sorry for the many questions

    Thanks

    XMaggotHeadX :)

    P.S. I have contacted DELL before. The first time, I was told the temps were too high, and the second time I was told they were well within range, so I have no idea what to think :/

    These are normal. It's the way the the chips were designed. There's a whole thread about temperatures here. The GPU and CPU will throttle and then shut themselves off before they're in any real danger, but that would only likely happen if you blocked all the vents on the computer simultaneously.
