So I have a Compaq CQ50-215CA and my sister was using her laptop on her bed and I was just using it quickly to check my email. The surface of the laptop was really hot and I opened Speccy to see that the CPU and GPU temperature was 96 C. A couple months ago, my laptop was on the desk without a cooling pad and I was playing a game. Using GPU-Z back then, I had a reading of 104 C. Even with a cooling pad on a desk, running several processes/games keeps me around 88-90 C.

Is this normal for a laptop and what's the highest temperature the internals can handle? Besides a cooling pad, are there any other more effective ways of cooling a laptop?

  • If you have fast AMD CPU there - thats normal. We had about 100 laptops in company, all AMD mobile processors were terrible, they produce a lot of heat, kill batteries quick. AMD is one or two ages behind Intel in nanometer race. I will never buy laptop with AMD CPU, but thats just my personal opinion.

Numbers I like to go with for laptop innards are:

0-40C = Cold.
50-70C = Typical-ish use, still safe.
70-85C = Heavy use, consider moving to flat surface, elevating, or cooling it.
85+ = Hot!  Go take a break.

Considering your machine uses a Turion QL-60 1.9Ghz Dual-core, I'd say something's working REAL hard, or it was on that bed roasting for a good amount of time. Found spec doc here, not sure if it's accurate though : http://h10025.www1.hp.com/ewfrf/wc/document?docname=c01550109&tmp_task=prodinfoCategory&lc=en&dlc=en&cc=us&lang=en&product=3805752

I carry an Everki Chill Pill for when I'm on-the-go: http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=5384436&CatId=3486 -- It's a simple little bean that splits in half and elevates the notebook about half an inch, which is sufficient for my machine. ymmv.

I have a Logitech Alto Express at work, which has a curved channel that promotes airflow in addition to raising the unit to eye-level: http://www.amazon.com/dp/B000RZNI48?tag=gotapex A fancier model with a USB hub and a keyboard exist too.

I'm not too much of a fan of the cooling pads that forcefully push air through the chassis, but I know some machines can definitely benefit from them. I haven't had too much experience with these.

Cleaning out your machine like Dmatig suggested is number one though -- I cleaned out a friend's notebook after he deployed to Iraq. Red sand, and Kool-Aid Mix (absorbed moisture and turned into a thick sticky goo that attracted more dust and lint) had caked inside the heatsink fins and was choking the poor machine.


Thankfully, the thermal zones were obeyed and the machine downclocked or shutdown each time a dangerous temperature was reached. Applied some fresh heatsink paste and the machine was running much cooler.

  • Wow that's quite of bit of stuff trapped in there. What kind of heatsink paste can you get and where?

  • I used a whole box of Q-Tips, some rubbing alcohol, and a toothbrush to scrub the crap out of it. Got it clean as a whistle ;) I used Arctic Silver - nothing too terribly special. I think even Best Buy sells it nowadays. I get the jumbo syringe : newegg.com/Product/Product.aspx?Item=N82E16835100008 -- they sell smaller quantities though. They offer application instructions based on what shape your CPU core has (or if it has a built-in heat-spreader or not) : arcticsilver.com/ins_route_step2intelas5.html

  • I think your temperature grades are not suitable for all laptops. For example, my IBM t60p laptop was working at really high temperatures (CPU and GPU at 85-90'C under high load with clean cooling system). Some powerful laptops just work at high temperatures due to high TDP. I had 45W TDP CPU and 25W TDP graphics card, thats 70W. Now I have 35W CPU and 15W GPU and it works at 60-70'C at maximum load with same cooling system size.

All of those temperatures are extremely hot (in fact, my laptop would emergency power it down if it got close to that hot).

There are various things you can do to cool it down, aside from a cooling pad. Probably the most likely suspect is lots of dust inside of the case. I'd suggest either opening it up and cleaning off the dust with a can of compressed air, or having a professional do it if you're nervous about doing it yourself. You'd be amazed how much this can decrease temperatures. Don't use a vacuum cleaner or anything else, compressed air is the way to go.

If after this your temperatures are still extremely hot, as in your case (I'd say anything over 80c is worrisome), then it's likely a fan is failing, or there is a bad connection to the heatsink and they need to be reseated with Arctic silver applied to aid heat transfer. It would probably be easier to claim on the warranty if you still have one.

If you're still running hot after all of that, there are other more extreme options such as under-volting/under-clocking and the like, but really if that is necessary then that's bad design on the part of the laptop maker, or you got a dud.

Also, give this a read for more detailed descriptions:



Short answer: yes, the temperatures you mention are almost certainly too high for your laptops.

Long answer: the highest temperature the internals can handle depends on the manufacturer and model. Unless you feel like opening the laptop up, your best bet is to do the following:

  • Find the CPU model by looking at the System Information screen [I'm assuming Windows XP].
  • Google for the datasheet. For instance, if it's a P8700, you would google for {P8700 datasheet}.
  • Download and open the datasheet. Look for a section named something like "Maximum Ratings"; this section will have either a maximum storage temperature or a maximum running temperature.

Alternately, you can try finding it in this list, but it's a bit out of date.

  • According to this, the Turion in his machine appears to be able to operate at 0-30C ambient temperature, with a max die temperature of 100C. amd.com/us-en/assets/content_type/white_papers_and_tech_docs/…

  • So, if I'm running above the "max die temperature" for a few minutes, how bad would the CPU/GPU be damaged?

  • Damage? Hard to say, usually if it gets too hot, it'll simply go up in smoke and it'll stop working altogether. Most modern CPUs (post-2002) will automatically throttle the speed or shutdown if it gets too close to what it considers a dangerous temp. This document just states that it's designed to work at up to 100C, but doesn't say what happens beyond that. I wouldn't say up to 100C is safe, because that's still awfully hot.

You could try this:

0 to 80 Fahrenheit: Cold enough to be safe

80 to 120 Fahrenheit: Typical usage, still safe

120 to 180 Fahrenheit: Heavy usage, consider getting a desk fan

180 to boiling point: Computer will downclock or shut down

Boiling point to infinite: Computer will shut down

All those temperatures are way too hot(in fact, my desktop will shut down if it's 212 F).


I've seen laptops to shut down at boiling point, and some laptops (cutting-edge)could even work at your temperatures without overheating! But for yours, firstly, I have some suggestions.

  • "180F to boiling point" - the boiling point of what, lead?

  • The evaporation point of water. For example, if you have a 212 F stove, and you boil water on it, all the bacteria will be killed. The boiling point, 212 F is when you boil water, all the bacteria is killed.

  • @Chris "all the bacteria will be killed" - more nonsense. There are bacteria that survive at 266 F.
