  • Does the iMac G5 get too hot?

    Greetings to all.
    I would like to start a thread about the iMac G5 and heat. I found a few old threads, but I would like to bring that topic up again.
    I have a 1st Generation iMac G5 (purchased end November 2004). For the second time since November 2004, it was defective and the Logicboard was replaced (so my Apple Dealer told me).
    First time, in November 2005, the screen went pink. Second time, earlier this month, my Mac didn't boot anymore.
    The full amount for the repair (including shipping to Apple (Belgium), work hours, etc.) was over 500.00 euro (about 700 USD for you, Americans).
    I believe that the iMac G5 (at least: my 1st Gen one) is simply getting too warm.
    The day before, I installed "Hardware Monitor". It gave the following (average) temperatures:
    CPU: 60.6 - 63.8° Celsius (141-164° F)
    HD: 57.5° C (135.5° F)
    It is my opinion that the (my) iMac is getting too hot to be "healthy". I have 2 PC's, in which I installed extra fans (at the back and at the side). One of these, with an Athlon64 3000+ (1.8 GHz) and a 120 Gb Seagate Barracuda gives (average) temperatures for the:
    CPU: 36.5° C (97.5° F)
    HD: 26° C (78.5° F)
    My second PC, an old (modded) HP Vectra, with an Intel P4 at 1.6 GHz and a 80 Gb Seagate Barracuda, gives as average temperature (HD only):
    HD: 37° C (98° F)
    It may not be correct to compare my iMac with PC's - but harddisks are harddisks, wheather it is a Western Digital (250 HD in my Mac) or a Seagate (PC HD's), and it is only logical that a(n average) HD temperature of 57 degrees Celsius (128° F) in the long term can not be healthy, while the harddisks of my PC's are a lot, lot cooler.
    The PPC, too, gets much hotter than my Athlon CPU (and the P4 most likely too).
    Therefor: is my suspicion correct that the/my iMac G5 in general is getting too hot for its own good? Even though it may be summer here (Belgium), I still find such a difference in heat values between my iMac and my PC's not "right".
    Both the times that my iMac was defective, the Logicboard was replaced.
    Is it possible that in both cases heat is the problem (directly or indirectly) of the defects of my iMac?
    Basically we have a desktop computer constructed like a laptop, with all the hardware stuffed together in a very tight space. Why did they not keep the heat issue more in mind, when the iMac G5 was designed?
    I believe that the heat is a very negative factor in the/my iMac G5. If I will have to pay such a small fortune, every time my Mac breaks down, being a Mac owner will become quite expensive.
    iMac G5 (PPC), 17-inch, Superdrive, Mac OS X (10.4.10) 1.5 GB RAM, 250 Gb Western Digital HD

    Your Mac should have been repaired under the Apple power supply or video and power issues as long as your serial numbers were covered.
    As far as normal operating temps are concerned, my Rev A is at this moment, running at CPU T-Diode 144∘and my Hard Drive is at 128∘so your temperatures seem well within normal ranges.
    Yes, the machines tend to run a bit hot, but as long as the ambient temperature is not too high, they are fine. The failures were originally cause by a bad batch of capacitors but since those have mostly been replaced, the machines are much more reliable.
    Some people train a small fan on the back of the computer to keep it cool, that may help you.

  • The bottom of the computer gets very hot

    I just got this macbook pro MC721ll/a. The bottom of the computer gets very hot as it is sitting on my lap. I have never had a mac before but I don't think it should be doing that. Also, I don't hear any fans running. Is this normal?

    The OS keeps the fans at a minimal speed because running them any faster would needlessly use extra energy and make more noise.  Manually setting your fan speed won't wear out the fans because they're brushless AC fans (so they're not subject to any significant mechanical wear as they spin).  One thing to keep in mind about SMC FanControl: Apple engineers spent a great deal of time, and probably money as well, designing the cooling systems for the computer (both in terms of the physical systems, and the algorithms that control the fans and regulate the voltages of the components).  In addition, Intel CPUs have their own separate temperature monitoring systems which will severely throttle or even shut down the CPU if temperatures get dangerously high.  So even in the extremely unlikely event that your fans ever actually spin too slowly, the computer will still shut itself off before anything bad happens.
    And to answer your first question, it is definitely normal for the bottom of the Macbook to get hot because the body is made from aluminum, one of the best thermal conductors known.  Basically the bottom acts as a heat sink, allowing the Macbook to cool off more efficiently and run faster.  Most other manufacturers make the bodies of their laptops from plastics, which conduct heat about as well as fiberglass insulation or a mink coat.

  • First mac, is it getting too hot?

    Hi, I just bought my first macbook pro a couple days ago (15 inch 2.2 ghz, 4gb of RAM, 500gb @7200rpm) and was wondering if it is getting too hot. I have been playing a game on it and have been noticing it that it is getting pretty hot, so I downloaded SMC fancontrol to monitor the temperature. While I'm playing the game the temperature is anywhere between 80 and 85 degrees celcius at a fan rpm of anywhere between 2500 and 3600. I am just wondering if this is too hot or should be a concern to me. Thanks a lot.

    I would say those numbers are too high. Considering you can coagulate tissue at 70C. If those temps (80+ celcius) were correct, you would probably have permanent grey patches of skin that would eventually slough off leaving holes on your lap.  Ha ha. Seriously though those temperatures would coagulate your tissue.
    If you're concerned, get a secondary surface thermometer. Also I think there are companies that sell lap covers to put your computer on while you work.

  • Mac Pro in Desk will it get too hot?

    Hi I'll be receiving my Mac Pro on the 27th of March. I will be placing it inside my desk (not by choice as I have no other place to put it) It's surrounded on all three sides, there's no door, the front is completely open, Would it get too hot for my Mac Pro? Would it be best to cut an opening in the back of the desk behind the computer? Thanks

    Would the computer be ok if I plugged in an external usb powered fan and have it blow the heat out?
    Would something like this do the trick?

  • Are my processors getting too hot

    I'm not sure if my laptop is getting too hot. I got this program "SpeedFan" that says my processors are around 65-69 degrees C. Sometimes I will be playing a game and the computer will go into sleep mode all of a sudden. I'm not sure that it is attributed to the temperature of the processors or it is set to go to sleep at a certain time

    Get yourself a cheap fan blowing air directly at the MBP. Combined with a cooling pad, I got my MBP 17" with the very warm 8600M GT GPU to get down as far as 20 degrees celsius below what it was before (I was having a good 80-85 degrees celsius on the GPU diode from iStat Pro readings, terrible, considering the low workload!). So now it's around 65 celsius instead on low workload.
    The real problem with NVIDIA 8600 series cards, notorious in Dell and HP laptops (look it up on the web, it's a major debate and controversy in the news on NVIDIA), is that the instructions to cool it down by kicking in the fans are not properly calibrated with the actual temperature, so if you juice it and it warms up, the fans on my MBP for instance won't really kick in until it is very warm.
    Ideally, the fans would go faster at lower temperatures, scaling up nicely... I use the SMC Fan Control to crank 'em up before GPU and CPU intensive tasks such as computer simulations, movie watching, and video games playing.
    Hope this is of any help!

  • Tecra 8100 CPU gets too hot

    Well, some could remember my previous post about fan activation in my Tecra 8100.
    This notebook came to me as a gift by a customer, because screen didn't work. After a bit of research, the problem was the internal cold cathode, that was broken. Once replaced: yup! a free notebook for me!! It was a Pentium III 650 Mobile, with 64MB of RAM and a 12GB hard disk. I replaced all those componentes (that are now for sale, btw) and it now has a Pentium III 850 Mobile, 512MB of RAM and a 40GB hard disk. Some one gave me a PCMCIA 11Mbps WiFi card, and now how it is working, with Windows XP Professional and updated Toshiba utilities and drivers downloaded from Toshiba USA.
    What's the buzz? SpeedFan, Motherboard Monitor and other monitoring utilities reports temperatures of up to 72?ºC in the CPU. I opened the notebook and put thermal paste instead of the sticker the heatsink has. Temperature keeps high, and Toshiba Utilities even at "high performance cooling" settings doesn't make the fan cool the cpu...
    I have not hangs at all, but notebook case and pcmcia cards get too hot even with the system working with no apps running. Lowering the CPU clock or ratio doesn't help at all.
    I'm thinking of putting an extra fan somewhere to force air flow and that way cool the cpu, unless that...
    ...Toshiba could develop an utility that allows to directly control fan speed. I don't know if thermal management is hardware or software driven. If it's software driven, it should be easy to create a utility that access directly to fan and temperature registers. That would be MUCH better that simply let the computer decide when and how long to activate the fan.
    I'm sure that Toshiba engineers are busy with more important things that will not allow them to create the utility for us, so...
    ...what to check or do to cool down the CPU to more appropiate values?
    Thanks all!

    Hi
    Like in you previous posting described the Toshiba power saver controls the CPU and fan usage.
    http://forums.computers.toshiba-europe.com/forums/thread.jspa?threadID=12585
    This software works great and if you use the notebook as prescribed, you shouldn't get any problems and overheating issues.
    The problem is that you have changed all devices and parts on you notebook. The new parts are efficient but produce more warmness.
    On the notebook you can cool the CPU with one little fan and if it doesn't last out, it's necessary to decrease the CPU performance.
    This is a simple fact. All these functions can be set with power saver.
    Furthermore it's very important that your cooling module is clear and no dust and debris handicap the fan working.

  • Macbook pro fan making loud noises and going really fast. Now the fan doesn't work at all and my computer gets extremely hot almost instantly. Is there a way to fix it without having to pay a ton of money to have someone fix it for me?

    I've had my Macbook pro for about 3 1/2 years now. It has worked great until recently. A few months ago I noticed that the fan would always run really fast when I was doing simple tasks. After a few weeks/months, the fan was still really fast but it also started to make these loud noises. Now, it only occasionally makes the loud noise if I move my computer after its been stationary for a while. The fan no longer works at all and my computer gets exceptionally hot almost instantly when I turn it on. Is there a way to fix this problem without having to pay a ton of money to have someone fix it for me?

    You can try a SMC reset:

  • Macbook pro retina display 15" charger getting too hot... any advice?

    I have had my Macbook pro retina 15" since Jan 2014 and it has been working fine. Just recently, I have noticed that the charger block and the connector to the laptop gets extremely hot as does the actual laptop. I have looked around on the net and most of the discussions regarding this have been on earlier models. The charger block itself is so hot that it emanates heat and is too hot to touch! The plug into the laptop is pretty darn hot as well. When charging, I can't keep the macbook on my lap because it gets too hot.
    I have checked all the connectors and the connections of all bits involved and they all seem good. I have also tried to minimalise all programs that are running.
    Just wondering if someone can suggest anything, otherwise it looks like a trip to the store
    Many thanks in advance

    Bfore you run to the store try this SMC ret, it fixes

  • My iphone 4s gets too hot with ios 6

    Hi Everyone. Just joined the community. I noticed since I upgraded to ios 6 on my iphone 4s it has been getting too hot when in using it. i noticed it would get hot when using maps and playing games. it would not get this hot too quiclky on ios 5.1.1. I also read that some iphone 5 users have the same problem as well as 4s users with ios 6. Can anyone give me some feedback and info. on this ? Hopefully there will be a fix for this soon.

    Mines never did that until recently. It depends on your usage and apps.
    It's basically normal to get hot, especially charging. Now if you talking about oven hot then you have a
    Problem. All my friends iphone 4s does it, so it's normal. Streaming videos while multi tasking can cause it also.

  • Pin connector of ze2308wm notebook ac adapter gets too hot

    My pin connector of my ac adapter gets too hot whenever I'm working on my ze2308 wm notebook.  It doesn't whenever I set it on "Standby."  Is this normal like that of ac adapter?

    Hello dbuser!
    Welcome to the Forums Community! How long have you experienced the A/C Adapter getting hot? Were you using a different battery before the 6 cell?
    According the the e530 Personal Systems Reference the 65W Adapter is the correct adapter for the 6 cell battery. It is possible that you have a defective adapter. Does the adapter make any noise, buzzing or cracking sound? If it is making any noise there is a definete issue with the adapter you are using.

  • My iphone just doesnt charge it gets too hot nd says it needs to cool down it doesnt connect to wifi also doest keep a long charge doesnt download apps pretty much doesnt work

    my iphone just doesnt charge it gets too hot nd says it needs to cool down it doesnt connect to wifi also doest keep a long charge doesnt download apps pretty much doesnt work

    So bring it to Apple for evaluation.  Can you not figure that out by yourself?

  • My new 32gb iPhone 5 gets too hot during phone calls. Is this normal?

    My new 32gb iPhone 5 gets too hot during phone calls. Is this normal?

    Mine will get hot mostly if I'm in an area with poor reception.  The phone will juice up the power output to lock onto a signal and will cause it to get hot and battery will drain much faster.

  • Having problems with phone getting too hot when not in use

    Hi there -- I'm trying to figure out what I can do to fix this.  Recently I had to get a replacement S3 because my original shut off mid-use and wouldn't turn back on.  The replacement has been here for about a month and in the last 2 weeks I'm having issues with it getting too hot.  The first time it happened, I had it plugged into the stock charger for about 1 1/2 hours - and I had picked it up expecting it to be fully charged but it was extremely hot and had a warning on the main screen saying that the battery was critically hot and was not charging and the phone was nearly completely dead.  I unplugged it, took the battery out and let the main phone body cool down.  After about 15 minutes, the body felt like room temperature again, so I put it all back together.  It turned on, charged normally that night and all was well. 
    Now for the last several days, I'm having issues again with it getting hot at random times when I'm not even using it (and not charging it).  The last time, I downloaded a temperature app and it said the phone was nearly 105 degrees, and it felt the hottest right at the home button.  Later that night after it cooled down, I noticed that the battery wasn't charging at all and was depleting rapidly on the charger.  I restarted twice with no change and then took the battery out and let it sit for several minutes.  After that it began charging again. 
    With it getting hot so much more often now, I'm starting to worry about this happening when I need my phone for an emergency as I spend a lot of time on the road transporting my kids to school and activities.  Is there a fix for this?  It doesn't appear to be the battery because my husband and I have the same phone and I've already swapped batteries with him - same issue for me, no issue for him.  Please help?  Thanks!

        Hello Micheliu813, let's get to the bottom of this together! Are you using the same charger that came with the phone or a 3rd party charger? We can also test the phone in safe mode to see if the device heats up again. Check here for steps: http://vz.to/1kb9LUM

  • My phone gets too hot Everytime I use it, why? I don't know what to do!

    Everytime I use my iPhone 5s it gets too hot. I've done everything. Even while charging it gets too hot. It's been like this for 2 days straight and I am compeltely baffled. I barely have any apps on my phone so I dont understand as to what the problem is…any help?

    So what does 'everything' mean? You've done each of the following 4 troubleshooting steps; restart, reset, restored from backup, restored as new? If so then you likely have a hardware problem and it needs to be examined at an Apple store.
