Heating Problem

  1. Hi All.

    I've recently noticed my laptop is getting hot readings and I was wondering if any one might give some advice on what it might be.

    I have noticed it most often when I am watching streaming vids. It sometimes gets up to 85-95 degrees when watching a youtube vid but other times it remains at around 60 when watching other youtube vids.

    I was having problems with shockwave crashing sometimes, so I went an made sure I had the most updated player. I started keeping an eye on my temps. and noticed that when I start up, it can even get up to around 80 degrees as well, and if running an app. like an adaware or virus scan app. it can get as hot also and shut down.

    I took my laptop apart over the weekend, cleaned out the fan, and heat sync (wasnt much there at all), and any other spaces there might be build up, but I am still getting these high readings.

    I dont see it as being browser related, as Ive run chrome, IE, and firefox, and still get all the same temps. It cant be graphic card related because if I run an app when i have nothing else open it still gets these temps, and the weird thing is, when I put my hand near the exhaust vent, the air coming out doesnt feel like it's as hot as it should be with these readings.

    I also checked my CPU and sometimes it's at 100% reading when it gets this hot, and other times it might be at only 43% or so and still gives me these hot readings.

    I am using Notebook Hardware Control to determine the temps. and just to make sure I wasnt just getting bad readings from it, I turned it off and ran a simple app. and the fan reved right up like it would if I had it running.

    Curious if anyone has any ideas on what it might be. Thanks in advance for any advice.

    PS. If I have nothing running at all, or just say gmail open, after a few seconds, it will go down to normal operating temperatures. I am also running 2GB of crucial ram, and it says I have plenty in Task Manager when this occurs. Than you.

    We still dont know what kind of notebook and specs you're running.

    Are you always having your notebook on a flat surface when using it?

    Hi Super. Sorry about that. I am running an Acer Aspire 3000, with Windows XP, 2GB of RAM, AMD Mobile Sempron 3100+ CPU, SiS M760GX integrated video card, and I keep my notebook on a LapCool2 Chill Pad. All of my drivers and bios are up to date.

    It's about 3 years old now, and I'll probably be upgrading in the near future, but I would like to get a few more months out of it. I am just curious as to why it would just in heat temps. so much, all things remaining the same.

    Thanks.

    Out of curiosity as well, I have tried about 3 different chill pads and think they are a big ripoff from the results I have gotten. Ive only ever noticed a degree or two drop from the ones I've tried, if that. Has anyone had any luck with using one and seeing a decent drop in temperature (keep in mind that you havent done anything else besides tried a chill pad and have not cleaned out the fans etc. as well.)

    I think it's the other way around, that is, it gets hot because the CPU is running at 100%. Check the Task Manager to see what processes are causing it to run a 100%.

    Hi Mailpup!

    I have done that and it is a lot of different processes. Like I stated, I can be running any browser and it will get a high temp. reading like that. It could be using 100% of the CPU or 43% and I'm still getting the same reading. I should be able to run, for example, ad-aware, with nothing else running, and not have the CPU for 1. be at 100%, and 2. even if it's an app. with nothing else open, running at say 50% CPU usage, bringing my temps. up that high. Any ideas?

    Can you confirm the temperature readings in the BIOS? I don't know about laptops but BIOS's in desktops usually have system temperature readings.

    Edit: Hey. How did I double post?

    lol, no idea how you double posted, but as far as I know, I don't see how I can check BIO's temp. reading from my laptop. If anyone knows and can let me know how, I would be happy to check. Thank you for your reply, replies ;] haha

    When you first start up your PC or laptop and the manufacturer's logo appears, the screen will say you can press delete or some "F" key to enter Setup or the BIOS. Once in the BIOS you can navigate around to find where the temperature is reported. In some PC's it is called PC Health but yours could be different. Don't make any changes and when you exit the BIOS, just exit and don't save. Also, FYI, you can only use your keyboard in the BIOS, not your mouse.

    Sometimes the screen to press delete or some F key passes by quickly so if you miss your chance, just wait until Windows loads, restart and try again.

    Hi Mail. Thanks for the advice. I actually have tried that before and it only allows for me to change BIOS settings and nothing about temperatures. I have everything set to default as well, if that helps out any.

    I actually just watched a 5 part video series on youtube for example, and some of the videos played and temp. only got up in the 60's and others got up to almost the 80's. All videos were of the same file type and from the same user, from the same series as well. It's got me quite baffled. It's not only from videos either. I had previously thought it might have been a plug-in or shockwave or something, but Ive tried several different browsers, and it also does this when running apps. as well, without any other apps. running. Other times it remains at a decent temp. For example, as I am posting this my temp. is only a 52 degrees. Kind of weird,

    In reading your posts more carefully, I was probably barking up the wrong tree. It kind of sounds like maybe there is something wrong with the motherboard temp sensor in what it's reporting. The misreported temperatures are causing the fan to speed up and the laptop to shut down sometimes to protect itself from what it thinks is high temperatures. Well, maybe.

    Any evidence that the temperatures are actually going high? The exhaust air issue sounds like it might not be.

    Mailpup, thanks for asking. That's what seems odd to me. The air that is being exhausted doesnt feel as hot as it should be reaching those temperatures. It's actually almost cool, but the fan is whirring away like the thing is about to explode. Is there any way you know to test the motherboard temp. censor? I don't even know where to begin with that one lol.

    I also don't know how to test motherboard sensors. For desktops I believe there are aftermarket temperature sensors that can be installed for case front panel displays but for laptops I doubt if there are any.

    The only other thing I can think of is cleaning and reapplying thermal compound and reseating the heatsink/fan on the CPU in case there is not full contact between them. Maybe the compound has deteriorated or has broken its bond.

    Thanks Mailpup. I will try that this weekend and I appreciate all you help. It's the only thing I can thing of as well. I actually just closed all apps. and checked my email using Outlook, and it got up to about 78 degrees which is really high for that, I believe. Thanks again!
