• Which the release of FS2020 we see an explosition of activity on the forun and of course we are very happy to see this. But having all questions about FS2020 in one forum becomes a bit messy. So therefore we would like to ask you all to use the following guidelines when posting your questions:

    • Tag FS2020 specific questions with the MSFS2020 tag.
    • Questions about making 3D assets can be posted in the 3D asset design forum. Either post them in the subforum of the modelling tool you use or in the general forum if they are general.
    • Questions about aircraft design can be posted in the Aircraft design forum
    • Questions about airport design can be posted in the FS2020 airport design forum. Once airport development tools have been updated for FS2020 you can post tool speciifc questions in the subforums of those tools as well of course.
    • Questions about terrain design can be posted in the FS2020 terrain design forum.
    • Questions about SimConnect can be posted in the SimConnect forum.

    Any other question that is not specific to an aspect of development or tool can be posted in the General chat forum.

    By following these guidelines we make sure that the forums remain easy to read for everybody and also that the right people can find your post to answer it.

Overheating.....

......and not just me.

The past couple of days I had three occasions when my development laptop shut down unexpectedly. The only common factor was that I was debugging ADE at the time - ouch you might say :o:o

Some research led me to overheating of CPUs, etc. Rubbish says I :rolleyes:

Well just to prove a point I started monitoring temps. On average the core temp is around 55- 60C. Start Visual Studio 2010 and things warm up a bit but not that much. Now run ADE in debug mode and the core temp shoots up to 85+ and it would seem now and again over 90C where my laptop is programmed to turn itself off rather than catch fire :eek:

This worried me - is ADE a secret arsonist :confused: Well with some trepidation I ran it normally from my normal installation. The temperature gauge could not be bothered to flicker much more than a few degrees. Core temp still comfortably in the 60s.

Before anyone suggests it - yes a laptop/notebook chill pad is ordered and in the post ;)

However I do find it somewhat ironic that the major MS development tool seems to be able to get my computer all hot and bothered as well as doing the same to me :D
 
Jon,

I fried an XPS development laptop, that ended up being those bad 8800 GTX cards that Nvidia made. But the only thing that really heats up my new one is when I run photoshop and FSX at the same time, really depends on how the laptop is made as to how well it cools, I have had the Toshiba qosmio for almost a year now and I can leave it on for days and it never has an issue apart from that, but it has never gotten to the temps you report. what laptop are you using btw?
 
Hi lads,
I just though this may help you with your overheat laptop.if you can your hand on a air compressor and blow sum air in to the back of your laptop at the fan end.that will remove any dirt or dust from your laptop that cost it to overheat.as my younger bother had the same problem and now it is sorted.
 
I don;t know what laptop manufacturers do (or don;t do) ... but heat has been a problem after about 3 years with my last 3 laptops.

I presume this has something to do with the heatsink used ... and I too have taken the soft option of using a notebook cooler.

I doubt ADE is the problem, but it probably represent more load than the idel tests.

FSX is a moderate test. If you really want to test your cooling system (not for you at the moment Jon!) IntelBurntest works everything hard. Ouch!
 
I'd just like to add that if all of the obvious issues don't address your temperature problem, I'll bet your heat sink isn't making as conductive contact with your CPU as it was originally. A situation I've run into once before but it was a relatively "old" laptop.

Modern laptops are laid-out more maintenance friendly so getting access to the CPU may be as "easy" as removing the keyboard or the back case. Carefully and methodically dive in there and replace the old, and probably dried-out, thermal compound.

Of course... this would be only something deemed worth the effort if everything else fails.
 
Thanks guys. I will certainly check the dust issue - we do seem to live in a dusty house! Then the chill pad is due tomorrow so I will see what effect it has overall.
 
No doubt about it, Laptops just aren't load or heat friendly. Might be better to vacuum the dust out rather than blow the dust into it.

I once came across a laptop that over heated when the fan stopped. it stopped because it was totally caked with lint and dust. Cleaning it out set it right.

Good point!
 
On my hot running Alienware M9750, I purchased a tube of new chip 'ointment?' (that thermal transfer gray colored stuff) and cleaned my GC and Chip surfaces, then applied fresh, new thermal paste to the chip tops, replaced the coolers, and Voila. I dont know what temps it was running before, and it does run hot, but at least now, I know its not only clean, but the older paste is now replaced and in fine working condition.

You might try the paste if its over 3 years old and has worked a hard life.

Another good idea Bill

I have the chill pad in now and I am running some 20C cooler than without it. Should help with overall performance as well. Mind you I do need to get the vacuum onto it as well :eek:
 
My Mother lode PC toasted itself last week. I was running fsx then all the sudden it started flikkering like an old movie and never said good by to me....the 3 year old lady past away burning its heart in fractions of a second. I did notice on my heat checking software a week or so earlier that it sometimes got temps of 80-90C which obviously were tell tales she was about to visit PC hell soon.......beware of the "grey glue" stuff, if you have to use it make sure you place it at the center of the cpu and spread it outwards very very thinly, if you make a glue glob it does not do the job it is suppose to do....I am now having very expensive free time since I ordered a new machine which must be covered with gasoline since the Payola has been very steep like going to the pump..........:eek::eek:
 
Since I put the chill pad in I have not had any problems. Mind you I have monitoring software on and I have set the alarm at 80C - hopefully would give me enough time to hit the off button if needs be.
 
Ive had the same problem where my laptop shuts down unexpectedly as if I pulled the battery out. Lemme specify the sequence.
I first play music in WMP. That is my alarm. As soon as the music starts chopping up, that's when I know something is about to happen.
The screen then turns black and the audio stops, then after 3 seconds or so, the whole laptop turns silent...

I first noticed this while playing FSX after I had the laptop for 3 quarters of a year. (Might I say the Laptop is a Samsung R580?)

It proceeded to get worse until I couldn't even fly on FS for 10 seconds without this whole situation happening. I decided that I'd send to for repairs, but my procrastinative nature held it off for a month.

It eventually got even worse until I couldn't even watch a video on Youtube!

I then did my own research. I came to the conclusion that when the laptop was using it's graphics card in a flow (e.g playing a youtube video, running an FS flight, etc.), the situation occurs. However, when all such programs are minimized and not active while Windows Media Player plays a song, the situation never happens. This lead me to believe that something was wrong with my graphics card.

Seeing as it also happened to you, Jon, could it be possible that something is wrong with Samsung Graphics cards in general?

FYI I don't know whether it's the graphics card or the video card, and I don't see the difference, so Ill assume they are both either the same thing or are both malfunctioning.

It's your call now. My laptops sent for repairs and I'm using my father's old laptop. :rolleyes:
 
Since I put in the Chill pad I have not had any further problems (fingers crossed) I am monitoring my CPU temp and it is at least 10C lower all the time than before and some times more. The issue is that if the CPU temp exceeds 90C the laptop shuts down to save itself from frying.

This is a 580 so maybe they run hot. For sure that have more powerful graphics than the average laptop which may explain why graphic intensive processes cause it to get all hot and bothered
 
But the problem is that the music stuttering (Which I mentioned is a warning to the laptop shutting down) stops immediately when I minimize all graphics or video programs. However, temperature takes time to bleed off. That is the only reason why I excluded temp from the issue.

Not to mention that I can make this happen immediately after startup, but temperature takes time to reach its peak.

However, I've seen laptops with a built-in mechanism to stop itself from overheating by shutting down, but the shutdown is immediate from that and not over a span of three seconds, so...:rolleyes:

I'm not a computer expert, however, but I read somewhere that dust might be the issue. I don't know whether that's true, but it makes sense since I also live in a dusty house...:duck:
(I really need to clean this place...)
 
Alright, nevermind, the fault is apparently not in the heat sink.

Repair Details:
Replaced the motherboard and HDD and verified the Notebook for proper operation.
CHECKLIST: TESTED THE FOLLOWING 1. HardDisk 2. CD/DVD Drive/Writer 3. Keyboard/Touchpad 4. Battery 5. USB/IO Ports 6. Display 7. Audio

Oh and they even cleaned the dust off the laptop for me! :D

I'm going to test FSX at it's highest video and graphics demand, and come back when I "get the test results."

If it doesn't work, then I'll check the heat sink.
