Laptop overheating issue?

[Wessex_Electric_Nutter]

One for the gurus to think about. It is an Acer Aspire 3023WLMi Laptop, recently upgraded with a Turion 64 (ML-37) processor, than the original Sempron 3000+ processor.

Recently, I started running into trouble with the temprature of the thing on one temprature sensor, since I installed Windows XP x64 edition (the problem didn't manifest iself under Vista/7, but Launch manager gave me hell.).

Anyway, my temprature readings at idle:

Anyone know what is TZS0 and if it should be that high? When I play a game and the temp hits 84C, either the GPU/CPU clocks down and causes some major lagging issue. The lagging is very smooth, like the graphics are being drawn at the right speed, but the game is running about a quarter fast than it should be, rather than a frame at every second.

There is 2 things I can think of, either my thermal compound for the GPU is crusted up and no longer effective (I hope not) or the CPU is too hot for the system, in which case, it shouldn't, because the FPUs are virtually identical!

Any other suggestions?

How did you upgrade a laptop CPU? Most laptops you can not upgrade the CPU and the cooling is made to fit the CPU.

Supprisingly easily actually. I know the laptop can take a Socket 754 CPU. The Sempron and Turions are electrically compatabile with the sockets, the thermal parts are the same (see here):
http://www.zandparts.com/acer/index.php?cPath=561_562_612_4808 (3020)
http://www.zandparts.com/acer/index.php?cPath=561_562_622_4809 (5020)

The motherboards are identical:
http://www.zandparts.com/acer/index.php?cPath=561_562_612_7102 (3020)
http://www.zandparts.com/acer/index.php?cPath=561_562_622_7103 (5020)
(LB.A4601.001)

So, the parts are the same, virtually, but the processors are different (its called modulisation, it makes sense to have a load of carcasses to be identical with the final finishing, left down to interal configuration.). There are no jumpers, so with some TMI, it was just a straight swap and power up to see if it works.
Its 4 years old anyway, so I have nothing to loose.

tzs0 is either the thermal pad under the cpu (motherboard temp) or the thermal coupler on your laptops video card. seeing as theres already two sensors for cpu and motherboard then id say its the video card.

you could try speedfan ( http://www.almico.com/sfscreenshots.php ) and see if it gives you a labeled view of the sensors.

Most likely when you installed the new CPU you nudged the GPUs heat pipe and it's not making a solid connection. While its open it may be a good time to re-apply thermal compound to the GPU.

Its closed up actually, I did this a while ago. And yes, I thought the heatpipe might be an issue, although it is screwed down to the motherboard on the base, with 4 - 6 screws.

At least I have the problem sort of identified, the next step is to open the case and try again. Another few mills of AS5 gone then.

That doesn't work, I get Temp 1/2/3. I think I'll stress the CPU/GPU seperately and see what happens.

This may sound silly to people who know more about the inner workings of these things than I do, but I added little stick on feet to mine. They are just little adhesive rubber discs that prop mine up a little higher than normal allowing more airflow underneath so it can breath better. And of course always use it on a hard surface.

I have an Acer Aspire 1703SC that was overheating and I used some 50mm timber to raise the rear even further. Don't know what the temps are but is way cooler to touch. Are you using an internal battery? I've had problems with charging causing overheating. In fact I've ordered a new battery before they stop manufacturing them for my laptop which is older than yours.

Funny you say that, because that is one of the first things I thought of, because my sister used to own it (does that say a lot?), all 4 rubber feet are missing. So to counteract this, I've raised the laptop further than the feet, by using anything with a height advantage, like a DVD case, DVD drive or its own power supply. (Yes, the latter tansferrs heat from another source, but surely, the PSU is far cooler than the laptop, right?)

Internal battery? Yes, I am, but its not even 5% and its 4 years old. Although Acer do stop making batteries, there are Aftermarket batteries, how safe some of them are, is a different question. (Rest assured, most won't contain the dreaded Sony cells!)

Yeah, when my sister and I roomed together, she would sit on the living room floor with her laptop right on the carpet. And yes, she fried it. At least she knows better now.

I would check your fan, Thats what was wrong with mine...

I don't think there is anything wrong with the fan, its not making any noises, the CPU is being cooled adequately, but the GPU isn't and thats what I want to know.

when you swaped out the cpu did you notice a compound smeared on ur old cpu its called thermal paste it helps with getting rid of heat if you didn't put any on your new cpu that could be the issue but ill ask my buddy who dose computer recycling and repair.

 

[skol587]

also clean out the dust bunnys

Like I wouldn't of checked that when I took the damm thing apart.

Replaced with artic silver 5. (Bad idea I know). Please re-read, its not the CPU overheating, but the rest of the system.

They make cooling pads for lap tops. The lap top sets on them and they pull the heat out. Some even have extra usb plugs on them for peripherals. My son had to get one for his and his wife's lap tops as they were overheating. Some lap tops run hot out of the box, depends on the brand.

I'm running a Toshiba, and withen 15 minutes of running TRS2009 I'm overheating and it burns, literally burns.

Thats getting VERY close to failing if it is getting that hot! CPUs aren't designed to take anything above 90C IIRC.
