Hello, the intervals at which I visit this website is slim and the amount of time I spend here is even smaller. However, this is a great community nonetheless and I hope people are still as helpful as before even though I may have been away for months.

So my laptop is acting rather weird lately. It has for a long time now, and it is starting to grow on my nerves - especially now Tera is out.

This only happens in 3D games. There are no problem with blue-ray, dvd, movie streaming online, or any other form of 2d application - just 3D games. Let us for explanations sake pretend I play a game right now, and my fps is 30fps. Suddenly fps drops and it is now 3. There was no reason for this big drop to happen - I did not even rotate camera or press a button. After 15-30 seconds, fps is back at 30 just as mysteriously fast as it dropped. Another two minutes go by, and fps again drops to 3. This repeats for as long as I play a game - any 3d game.

What can be the cause for this? Is it an overheating issue? And what can I do about it?

Download Temperature monitoring programs like CPU-Z/Core Temp/GPU-Z and look at the temperature readings. If its very high (above 60-70 degrees C) then its probably overheating.

Well I downloaded Core Temp, and GPU-Z. Both applications are currently running alongside Google Chrome.

GPU temperature is 66 degrees Celsius.
CPU temperatures are 62 degrees, and 62 degrees Celsius.

This is with no 3D Application running in background or foreground. I suppose it is an overheating issue if these values are this high during idle web browsing. (edit: I mean because during a 3d game, these temperatures would no doubt rise ~10-20 degrees.)

Is there anything I can do about this? As I said previous, this is a laptop.

Intel CPUs have a much higher operating temperature (72°C for an i7) than AMD (62°C with my Phenom II x6 1090T). What CPU do you have and what temperature does it rise to when you play a 3D game? The CPU isn't the core component in gaming (all it does is control user input and data flow between RAM, HDD, GPU etc.). You'll rarely see it rise above 20% usage when running a game.

The core component in gaming is the GPU. Again, there are huge differences in maximum temperatures. My GTX 580 operates at 97°C. What temperature does it reach when you run a 3D game and what GPU do you have?

Hmm, well the GPU is just about at it's limit. What GPU do you have?

The CPU is friggin' hot! Isn't 92°C the point where it sublimes?

I have geforce 130M (image).

And I have no clue about cpu temperatures, sorry. I was only assuming it could be overheating issues - which it probably turns out to be.
So what can I do, there is no way for me to open the case and remove excess dust because requires special tools to open. I still have some months left on warranty (it's nearly three years old now) but I am not sure it would be possible to deliver it for a check up, would it?

Its likely an integrated graphics card, puts more load on the cpu, using virtual memory rather than having their own dedicated (though it likely tells you its 250mb or whatever), leading to overheating.

Edit: you posted as I was writing this, dont know for sure if that particular card is integrated or not. Looks like it should handle it maybe its having problems.

If its still under warranty I would take it in.

Awesome! Its one of those threads.

A quick google says that the GeForce 130M has a maximum temperature of 85°C. I've also found that other people are experiencing the same problem. I suggest cleaning all of the dust out of your laptop (it's amazing how much it collects in just a few months). Just don't do it like this:



If the problem persists and it's still under warranty, you should take it in.

Dammit. That's how I broke my GTX 260M in my laptop. I guess it worked but then sparks started coming out of my laptop.

This reminds me of that troll that said he filled his computer up with water after plugging all of the holes with silicon paste. Does anyone have the link to that forum page?

Ok, thanks for the help! I will see if it would be possible to buy the correct hardware to enter the computer case. I need a long slim tool to enter, where there is none in my toolbox.

Anyways, let's hope it is only dust after all. Would make it quick and easy and could enjoy Tera some more, heh.

@TheComet

what makes to you think putting the board under the tap is a no no.

Used to do this all the time when I worked in electronics, mind you it was deionized water, but other wise it was safe as long as was not swicthed on when wet, dry it out in the oven at 50c and it be all ok.

Does your laptop light flash when it start doing this?
Read somewhere that this an early warning that it may shut down.

Nay, there are no signs anywhere on the laptop that something might be wrong and it wants to shut down (heck, even windows update doesn't even let me know he wants to make a restart sometimes).

What happens is, obviously fps is very very low - and sounds are distorted. Think of it like you play a video in slow motion, audio gets quite choppy.

And would it surprise you if I said I've already delivered this laptop once for repairs - because he got so hot it melted my power cable

I see, just thought that might have been it.

Also heard that taking the battery out of a laptop will stop it killing the battery when on the mains, wried or what.

Before I got my Alienware serviced, the cpu used to go up to 100 degrees celsius (just like yours basically) and there was a fly in my room, and it flew under my laptop and died. Kind of funny.

Nothing really, it's just not the "typical" way of doing it.

Hey guys, I decided to test something else before I went ahead and open the case.

So I set the processor to select only one core for the 3d game (task manager -> set affinity). As far as I can tell this worked out well, one hour into gaming and no FPS drops as of yet. Surprisingly cpu core temperatures dropped significantly to 84 degrees celcius. CPU0 carry a load of ~8%, CPU1 carry a 100% load.

Is there any reason I should not set affinity from one core to handle the game? It looks like it solved my issue - but I am scared it will in the near future cause damage to my cpu.

Any ideas?

84 Degrees is still well beyond what I'd be happy running anything at, you should really clean your fans. I think the same operating temperature peaks around 70 degrees

Hello, I suppose this was only a temporarily fix. Now even running a game on only one core it will eventually (although after a longer time) create same issues.

Still I am curious to know if it is bad for the processor when I assign one core to handle a heavy task.

I have opened the case, and surprisingly there is no dust at all anywhere. It was quite clean actually, so it rules out the possibility of it being a problem with dust blocking heat from escaping.

So if it is not dust, and it is not dual core processor, it leaves me now with two possible situations, who are somewhat related.

1) GPU throttle. It will reduce or increase core clock, memory clock, and shader clock "as needed". If you look at my screenshot in the post above from Tera, you will see the memory clock has dropped from 800MHz down to 300MHz. Why it decide to do this during a 3d game is beyond my knowledge. But from some testing I have done in Minecraft (where I can run at 250+ fps) it is very noticeable here where core clock sometimes drops to 200MHz from its 600MHz native and my fps drops down to 1-2 fps.

2) Overheating. The reason it reduces clock rates would be an indication he wants to lower energy consumption (ie. heat generation).

My question this time is: Would buying a Laptop Cooling Pad help me?
My concern is if I went to deliver the computer for service, chances are they will send a brand new one in return - and how long until that new one wil experience the same kind of issues?

It does help slightly, your laptop temperature might go down atleast 20-30 degrees Celsius (For me anyway)
