    Default Acer Aspire 5738G heating problems

    I bought an acer aspire 5738G a couple of days ago with windows 7 x64 installed ,catalyst 9.9. When playing any game or using any 3D demanding application both my GPU temp. jumps up to 85-95 degrees C, and the CPU to 75-85 degrees C. according to GPU-Z my fan speed is always at 30% no matter how hot the lappy gets. I also wanna mention I didn't OC or use any modded stuff yet.

    My questions are:
    -Are these normal temps since this is my first acer and my previous lappy which wasn't an acer with a Nvidia Geforce GO7900 never got past the 75 degrees barrier
    - Is there something wrong with the fan or it is supposed to kick in only at critical heat point

    GPU-Z may be trying to read a desktop fan speed - do you hear/feel any difference in the fan speed on your machine?
    The Go 7900 might have had a more robust cooling system than the Radeon you've got, and thus remained cooler.
    Your temps are just getting into the danger zone - see if your fan intake and exhaust are dust-clogged (yes, even straight from the factory). If not, it might be worth your time to invest in a cooling pad or replacing the thermal compound.
    Sorry if I'm not around too often - life seems to have gotten in the way of NBR.

    Thanks for the fast reply mate,

    -I dust clogged my laptop at the store actually because I live in Egypt and I know that our weather is crappy.
    -As for the fan I think I hear a difference but if the fan is working at 100% and the heat goes up like that in a 20 degrees room temperature that would be disastrous.
    - I bought the laptop 2 days ago and to be frank with you the nearest service center to me is 4 countries away and I can't trust anyone here in the thermal replacing thing because they are not qualified enough and I don't wanna ruin the warranty

    Is there anything I can do ? I am new to both ATI and Acer so I don't know any tricks, also I was wondering if the one causing the problem was the processor or the GPU, I think both of them are 55nm so they should be relatively cool

    I tried like 8 fan control softwares but nothing worked for me,ATItools and Rivatuner didn't work because of the lame windows 7 driver signing thing and I found out that ATIoverdrive doesn't work with the HD 4570

    Well, you should be able to open up the bottom of the machine and use some compressed air to de-dust-ify the thing without voiding your warranty.
    I'd still look into a cooling pad like the Zalman NC-2000; something to increase the airflow of your machine.

    I am from Egypt too, i bought this laptop 3 month ago from compume, i never faced any problems with temp the Gpu and the Cpu never exceeded 65 degrees even when playing.
    I suggest you return it and get a replacement.

    I bought mine from a company in Nasr city called IBS ... I will contact them tomorrow and ask for a replacement because constant 95 degrees is quite annoying ..... Fodo can you tell me what operating system you are running and anytime you are free, can u Screen shoot a GPU-Z Maximum temperature page of your Radeon fully loaded like after playing for an hour or something?

    Thanks a lot bro for your help, I know it must have been annoying keeping track of the temperatures mine came with win7 x64 pre-installed and I am exactly 12 degrees over your max (94 degrees C) I think the performance of the X64s is higher than the X32s I will try to scout around to see if the x64 operating systems heat up more than the x32s and if so I think I will install a Vista x32

    They shouldn't - mine never has.
