Aspire as4750g CPU temperature

i7 2630qm
nvidia geforce gt 540m
4gb ram

When i am running Dragon Age Origins, the CPU temperature can easily run up to above 90 degree celcius. Is that a safe temperature, or is it even normal to reach that temperature. BTW, I'm not using any cooler.

 

The "maximum safe operating temperature" for these CPUs is 100C. When you reach that temperature, thermal throttling kicks in, and the CPU will slow down to protect itself from damage. If the temperature continues to increase and it can't be controlled, the CPU will simply shut itself off when it hits 125C to 130C.

Intel CPUs do a great job of looking after themselves. As long as your game is running reliably at full speed then there is no need to worry. Many Sandy Bridge laptops run hot because the cooling solutions provided are barely adequate. This becomes obvious when you are running any software that works both the CPU and GPU. Gaming is a good example of this.

 

Ok, so the CPU wouldn't cook itself, it got me worried for a while. Thanks uncle. However, would the temperature I mentioned degrade the CPU, is it necessary for me to get a cooler? BTW, I came across this information somewhere saying that if the laptop is used while plugged to an AC adaptor, the heat generated by the CPU would be higher, is that true?(curiousity)

Is my CPU over heating? SB i7 2630QM - Page 2 - Overclock.net - Overclocking.net
someone mentioned something about degrading

i7 2630QM Temperature......
and this about the AC adaptor

You mentioned that many of the laptops cooling solution are barely adequate, however thats the limitation of a laptop right? Do you know of any laptop that has sufficient cooling? Or laptops just are not made to do things like, e.g gaming ?

 

my Acer 3820TG reaches 78c in prime 95 with an i5 480m @ 3.33ghz, so some laptops are capable of cooling their components well. The fan is set to 100% and the room temperature is 22c.

The trick is, you need a dedicated fan for the processor.

 

I don't think I am capable of manually adjusting the fan speed. When using speedfan, I am not able to see any options under the fans tab. BTW, does your dedicated fan* means external cooler, or changing the stock fan of the laptop?

When running prime95 I got stable cpu temp of 80+- celcius. Within 10 minutes of dragon age origins my laptop reach 90 celcius. The CPU usage was about 60 % when running dragon age origins. prime95 was 100%.

Its a mystery to me...

 

By dedicated fan I mean one dedicated by the manufacturer to a specific component. My 3820TG has one fan for the CPU and one fan for the GPU.

As far as your test results, use CPU-Z to check if your processor is throttling with prime95. The other culprit could be the fact that your notebook's fan must cool the 540m in addition to the processor.

If you are feeling brave then run both prime95 and Furmark at the same time. These two running together should really give you an idea at how much heat the fan can dissipate.

I personally would not own a quad core gaming notebook with a single fan; the combined TDP of both the processor and the video card is almost always too much for a single fan cooling solution.

You've got two choices if you want your temps to be under 80c.

A) Run the processor at 75% speed

B) Buy a cooling pad.

My best advice is to do both.

 

I have a friend that wants to buy a laptop. I dialed up my local computer shop, asked about the price of AS4750G, later i mentioned about gaming with this laptop, told him about the temperature that I am experiencing. He said if gaming is of concern, I should get asus x42 model with AMD triple core processor(I think it is n830 or m830. He said that it was released half a year ago. Only released in my country 3 months ago). That guy said that this processor with newer technology would run cooler than intel i7 and also performing better than it. He mentioned something about the i7 with 1000+ something and the AMD with 3000+ something, didnt really catch it. Therefore gamers would use AMD for gaming. He even claimed that if the AMD has a problem with gaming, the i7 would have even more problem. He is even willing to show me that it is better than the i7 processor if i come down to the store. Later on, I called my cousin which is more familiar with computer, he told me that it is impossible for AMD processors to run cooler than the i7. He said that the AMD would definitely be worse than the i7 and generally AMD's processors runs hotter and poorer. I aint a computer savvy person, so my question is, is it true about the CPU or is that guy just trying to get me down to his store and convince me to get that x42? From what I read on the internet, the triple core processor seems to be definitely poorer, or am I wrong ? Is there a 2nd generation for this triple core processor or something?

 

My fiance has a gateway with a Triple core AMD phenom II and an ATI 5650. It runs hot to say the least and there is no way to control the fan.

I love AMD, and have a phenom II x4 in my desktop, but as far as mobile processors are concerned they are second rate.

Like I said before, the general rule of thumb is that a quad/triple core cpu needs its own fan if the laptop also has a graphics card designed for gaming. If you are not doing heavy video rendering on the go then a fast dual core (~2.5ghz) should suffice.

 

If Intel discovered that running a CPU long term at over 90C degrades it, they'd lower the built in thermal throttling point from 100C to 90C. They actually did the opposite. Some of the original Core 2 CPUs used a thermal throttling temperature of 90C and when Intel found out that their CPUs could handle that without any problems, they raised the thermal throttling point for the majority of their CPUs to 100C. The Core 2 mobile CPUs and the previous 32nm Core i mobile CPUs were mostly set to 105C. They are back to using 100C for the new Sandy Bridge CPUs so I guess they have found a happy compromise between long term reliability and performance. There's no need to worry about the core temperature of an Intel CPU. As long as it is below the built in thermal throttling point, it is running exactly as it was designed to.

 

Neither of us have visited the lab in which Intel tests their chips before they put them in mass production so we can't know exactly why they gave the new Sandy Bridge CPUs a lower TDP.

Intel gives the Tjunction number as the absolute maximum for the processor. Just because you won't see the immediate wear on the processor doesn't mean that there is none. Add living in a hot environment and the wear just adds up. Don't forget the wear to the motherboard and the hard drive when running at 90c+.

Even if you are not planning to use the laptop for 2-3 years and may not see the damage, someone else might. I personally miss the days when laptops lasted for 8-10 years if cared for properly.

Look at the current video game consoles, they have huge failure rates because of heat. My original Playstation and n64 still work beautifully.

Please, next time link an explanation for the picture.

AnandTech - Intel's 45nm Dual-Core E8500: The Best Just Got Better

There is obviously correlation between processor life and temperature/voltage. The difference between a cpu running at its thermal limit and one that is properly cooled is almost 5 years. The gap will probably widen if the difference in temperature is fairly big, say 20-30c.

 

You're right. I haven't visited the Intel labs. That's why I read and depend on their documentation.

"PROCHOT# goes active when the processor temperature monitoring sensor(s) detects that the processor has reached its maximum safe operating temperature."

90C is a big number but according to Intel, that is still below the "maximum safe operating temperature". For the Core™ i7-2630QM, the PROCHOT# signal (processor hot) goes active at 100C.

Intel® Core? i7-2630QM Processor (6M Cache, 2.00 GHz)with SPEC Code(s)SR02Y

This signals thermal throttling to begin where the CPU will rapidly adjust its speed and voltage while continuing to maintain maximum performance. This helps keep the CPU from ever exceeding 100C so it can continue to run at a safe temperature.

In the event of a complete catastrophe such as the heatsink getting loose, if the CPU can not control its core temperature by thermal throttling, it will trigger the THERMTRIP# signal at 125C to 130C which immediately shuts the processor off to protect it from damage. These safety mechanisms have been around for years and they work great. If your CPU is operating below the thermal throttling point, it is operating within the Intel design spec where it was designed to live a long and reliable life.

The core temperature reading comes from a microscopic temperature sensor that has been strategically located at the hottest spot on the CPU core. There can be gradients of 20C within a partially loaded CPU so the entire CPU and motherboard are not sitting at 90C.

The main reason the XBox 360 failed was because the CPU was not properly soldered to the main board. The CPUs didn't fail because they were degrading from heat so that comparison doesn't have much to do with a new Sandy Bridge laptop.

 

You mistake the difference between safe and lasting . Transistors in the core degrade over time and though the processor will continue to operate at the same efficiency it will not do so forever. Intel does not design the chips to have a long and reliable life while running at 90-95c. They design them to run near maximum operational temperature for an average of three years, the length of the processor warranty.

Factor is dried up TIM and dust in the fans and you have a short lifespan for an average computer user. Of-course an enthusiast can increase the processor's lifespan by taking care of the aforementioned things but even with these considerations the processor @90c will give out long before one @70c.

I may upgrade my processor before my current one wears out, but that doesn't mean that manufacturers should make notebooks that will force me to do so.

The Xbox 360 is an example of how heat, regardless of the specific parts it may affect, limits the life of allot of consumer electronics. People want smaller, faster, and quieter, and the truth is that you cannot have all of that if you want it to last.

I don't want this to turn into an ethical debate, but simply put the computer industry is fast becoming like the automobile industry: Bigger (transistors), Faster (clockspeed), and requiring more energy than ever before.

/end rant

 

The elevated temperatures will be running at around max.

Also remember your laptop may not be on all the time, nor will you be gaming all the time.

Lower voltages in laptops will mean the processor life will be increased as well as the lower frequencies.

 

Why am i double posting again ? can someone tell me how to delete an old post ?

Thanks guys.


I am not sure if overheating of processors is warrantied for AS4750G, but if not, maybe they want consumers to frequent them more often(1-2 yrs)? (;

I guess my laptop has only 1 fan to dissipate both CPU and GPU heat. But its ok, I bought it at a considerably cheap price.

Would a i5 2410m run cooler compared to a i7 2630qm when in use(gamings etc)? The friend of mine is getting the i5 2410m model of AS4750G.

I guess while trying to find a suitable cooler, I would run the CPU at 75%. Trying to figure out ThrottleStop..

BTW, doomseeker, you mentioned that your CPU is running at 3.33mhz? Am I right to say that you overclocked your CPU? What are the benefits of overclocking? Is it like expanding the potential of the CPU? So for example a stock i5 2410m can only run to max of 2.9mhz(is it because it is restricted/locked?). So *overclocking* frees it to reach 3.33mhz? Granting the CPU the capability to reach 3.33mhz, which would perform better(provided it runs under safe temperature)?

May I know what do your work as? Seems like your know much..

 

I overclock my cpu to 3.33ghz only when I am playing Zelda Twilight Princess or Metroid Prime on the Dolphin Emulator. It's necessary to overclock for those games because they are extremely cpu dependent. I only overclock because I can reach a safe temperature of 75c max with my notebook. My CPU can reach 3.6ghz at 81c max but I wouldn't run it that high.

You don't need to overclock your cpu for most things, it's fast enough.


If you want a good 15" quad core gaming laptop then get the Sager NP8130, it has two fans and a GTX560 graphics card.

If you want an excellent 13" machine then I would recommend the 3820TG if you can find one (very hard now). Avoid the 3830TG since it has one fan.

An i5 dual core will be about 5-10c cooler on full load than the quad core so yes I do recommend it for any notebook with a single fan.

 

Do your have any idea for the max temp for the gt 540m? Mine is running 80+ celius when gaming...

Why does Acer not utilize a fan for the GPU? Are fans that expensive? Or is it the battery life that they worry about... If so why does your 3820TG has? BTW, the acer website says that the 3820TG doesnt use the sandy bridge processor, would that put me in any disadvantage? Is it possible for me to disable 2 cores to make my i7 into an i5? Or is it not as simple as i think it it..

 

The max running temperature for the GPU is 105 degrees I believe, 80c should be ok during intense games.

The only way I know of how to disable the other cores is to start task manager after running a game, right clock on the game process, and then set the processor affinity to however many cores you want to utilize.

Here's the caveat, your quad core CPU is hyper-threaded, which means that each core has a second 'virtual' core running for a total of 8 threads. Your CPU will show up as having 8 logical cores even though you have only 4 physical ones.

Cores 0,2,4,6 are your physical cores and the others are the virtual ones.

You can try to set affinity for only cores 0,1,2,3 for a total of two physical and two virtual threads. You will of course experience reduced performance in games that utilize 4 cores but aside from GTA IV, ARMA II, Ghostbusters, The Witcher 2, and maybe a few others, you don't need all four cores.

you will have to do this every-time you play a game.

There is a way to do this through a batch file (a notepad file that executes several commands in order) but I can't remember how right now, try searching somewhere.

 

Wow! It does decrease the CPU temperature. When I ran with only 1 core, the temperature is even further lowered.

Am i right to say when 4 cores are used to do a task, it is actually 'faster' compared to 2 cores even if i cant feel it? When running dragon age origins with 2 cores and 4 cores, the performance seems to be the same. So why does running on 4 cores make the CPU hotter?

 

You only really need 30fps for the game to be smooth. up to 60fps is very smooth but is not necessary. The game is probably running slower on two cores but you can't notice as much because it is still over 30fps.

Here read this thread, this may help even more.

Required FPS varies on game, settings, display and user.
