I haven't seen any lower than 58

Hi everybody,

I know everybody here feds up with such questions but I got to ask. I have run MATLAB (mathematical software) for couple hours right now and I haven't seen the temperature any lower than 58C. Fans are working but temperature goes beteen 58C and 59C. I believe it is hotter than it should be but I would like to have your opinion too.(it is 88900 with 3.4 processor and 1gig RAM...)

58 Deg is really not that hot for a 3.4, especially when under such heavy load.

that definitly sounds about right. Mine idles between 50 and 60

What software are you guys using to moniter your temps?

You shouldn't have a problem until the temp is over 68C. At 69/70C the machine should shut down (Intel Specs).

If you have blinking Caps-Lock and Num-Lock lights, then it is a different story.

Mine runs 56C running prime95 torture test. Meassuring temps with mobilemeter.

thank you guys for quick responses, I appreciated.

Gomaha:

Dom02:
I don't know how heavy is that of running a mathematical software on it. Is it heavier than 3D gaming? I have even seen 60C and I am getting close to 68C and this scares me a lot. It has been only two days there shouldn't be anything wrong with the heat sink.(dust..) And I have a fair amount of noise that I can hear from even upstairs.

Am I exaggerating? I also feel uncomfortable hearin DVD noises whenever it sees CD in it and there is almost constant HDD noise. BUt still my main concern is that of having hight temperature.

Nandro:
Can you tell me some more about torturing the laptop? If it really tortures the system you have got really nice number over there and I envy you.

crabman: I use a MobileMeter and you can get from here(hopefully)

Thank you guys.

Obvious question : at what temperature (or temperature range) does the machine idle? What of running other more standard applications? Tracking down the solution could be related to Matlab itself, or perhaps something as minute as a driver/service conflict.

Ergo, it may be a software issue, rather than a hardware issue.

(if you are running Matlab, you might be interested in the aforementioned prime95, as it deals with the search for Mersenne primes - regardless of whether you make use of it for benchmarking or stability testing purposes.)

Right now I cannot give you the idle temp. because I have program running on it and I don't want to stop it. As soon as it is done with the code I will ppost the idle temp and also prime95 results. YOu are right about prime95 and I believe it would be a good exercise for the CPU. Thank you.

you go to http://www.mersenne.org/freesoft.htm and download the prime95 software and run it as a stress test. Its an option, you can stress the memory or the cpu its actually called system torture in options. It is a prog like seti@home that searches for the largest prime numbers in existance.

The largest Mersenne prime. A search for the largest prime would be an exercise in futility (as the number line stretches toward infinity, of course).

A Mersenne prime is defined as (2^p)-1, where p itself is a prime number.

esub, you can check out my review (http://notebookforums.com/showthread.php?t=20504) for my thoughts on the DVD drive. I, too, found it to be extremely loud. However, I have zero HD noise. Absolutely none. I don't know if anyone else is getting HD noise, but that would bother me just as much or more than the heat issue. Which HD do you have? I've got the Hitachi 60gig 7200. Absolutely quiet.

esub,

Are your fans "screaming/roaring" somewhat like a hair dryer or is it "bursting" for a while and then thuring down to a lower setting? Have you experienced the blinking CAP-Lock and Num-Lock lights yet? You stated that you say 60C and then alluded to a reading of 68C. What is the highest temp that was actually observed? If you are seeing temps in excess of 68C, I'd be real hessitant to continue using the unit - especially if the fan is not ROARING.

I think you worry too much, something that is CPU intesive is going to drive up the temp. When I run Seti (100% CPU utilization on both main and virtual processors) my CPU temps get up around 62C with a 3.0ghz 8890. I don't think he said it ever got over 60C on his. He mentioned the 68C in reference to Bratag's post that said "Thermal Spec 68°C." Its fine as far as I am concerned, its a desktop processor and you are working it hard from the sounds of your posts. Everything is normal.

Jeffro. If he has the blinking lights then there is a serious problem about when his fans start and stop at "maximum cooling setting". 59C - 66C for a totally "stressed" machine is OK, as long as the fans are operating correctly. See my review thread. I totally "maxed the machine" and it functioned well, At 67C the fans turned to turbo and then the lights started blinking. Fans would not turn off even when the machine was shut down in Windows. It also caused the battery to "Fry" with 56% capacity remaining.

He may or may not have something to worry about depending on the answers to the questions I previously posed. As an FYI, the 3.0 GHZ processor has a 70C tollerance where the 3.4 has a 68C tollerance.

Peace

Try running four or five instance of Seti at the same time. The "Max CPU" temps should not vary if the cooling system is working properly. Just DO NOT DO THIS ON BATTERY POWER!!

Right now I don't hear any roaring or screaming fans and temperature has never got lower than 58C. I haven't notivced any blinking cap-lock or num-lock lights but should I wait until see one of them? Being close to maximum operating temp. bothers me alot. So far highest temp. observed was 61C. I don't know what SETI is but I am guessing it is a game and I don't think I could play that game in my machine without breaking the barriers.

jeffro:
Yes, I said minimum temperature is 58 I have seen so far while matlab code is running,but I have seen 61C. I don't think Matlab code should cause such a trouble because I run same kinds of codes in other laptops too and I haven't seen this issue as a problem.

I am considering to run Prime95 as soon as matlab code is done but I would like to hear something about SETI too. Is it not a game? Is it like test suit? I will do some online search on it.

Well,this machine arrived yesterday morning and it has been running since yesterday afternoon. Air irculation was good, all windows were open and room temperature around 20C if it helps.

Thank you very much for your time and consideration guys.

SETI: Search for Extra Terrestrial Intelligence

SETI@Home: Use your PC to help analyze space recordings

It's a similar concept to Prime95 - a distributed effort to use many computers to analyze small parts of a greater whole.

MatLab, depending on what you're asking it to do, could certainly tax the CPU enough to hit upper 50's. The P4 is a HOT CPU. I can run Prime95 or other CPU taxing programs on one of my Celeron-based laptops and never hit the same temperatures, so comparing the 8790 to your other MatLab running laptops wouldn't be a fair comparison.
