Acer 3830TG(-6412) overheat and shuts down

DaoHeng

Hi,

I have an Acer 3830TG and it's about 2 years old. I also installed a fresh copie of Windows 8 Pro and then upgraded to Windows 8.1 preview build 9431 with Media Center.

 

Since I first purchased it, it had slight overheat issues (50-60c when idle). 
Two years later, the average idle temp is still the same, but whenever I play a game and the CPU reaches 85c, it shuts down. From what Intel(R) says, my CPU can withstand without problem a temperature of 105c, but my hardware doesn't seem to understand that. Also, I experience extreme slow performance when the CPU reaches 75c+.

Thanks for the answers

Dao, someone misunderstood something when they told you that your rig can easily handle 105C. At the temperature, moisture in your machine will boil into steam. You would burn your hand touching the machine, and the plastic parts would melt.

 

Run your finger over the exit vent to make sure that your fan is running. Merely elevating your rig a little will lower the temperature 10F. Carefully blow a shot of compressed air into the exit vent.

 

 But you probably need to take it to a shop and have your fan replaced.

I'm sorry if I forgot to mentiion I have cleaned the fan and air grids, my laptop is elevated by about 1cm with books, on the corners, and I've even replaced the thermal paste. I am sure the contacts between my cpu-gpu to the cooling metal part are fine and the fan, 90% of the time is running at its max speed. 

I wouldn't consider replacing the fan, since the laptop is three years and a half old and it would not be useful in no long time.

PS: Also, I didn't say my rig can handle 105c, I said my cpu can. It wasn't anyone that told me that too, it was Intel(R) itself. Problem is that I know I cannot push my cpu much more, but I don't like whenever I do something CPU intensive, it immediately cuts the power off.

Thanks annyways

First " fan, 90% of the time is running at its max speed. " it isrunning or being commanded ? If running at 85C you should feel hot air coming out the vents.

Sounds to me like you either have a bad/jammed fan or the air path is blocked. It is going to have to come apart and be checked.

 

BTW if the fan is a standard size, they are not expensive on Amazon. I have replaced fans before.

 

Final thought - fingle and dual fan collers that fit under the notebook are under U$10.00.

Hi, 

Uhm my fan is not being commanded by a third-party software, it is running on its own at its max speed. And also, when you say if I feel hot air from the vent, I tell you you better not leave your arm there for longer than a minutes or else you might end up burned up.

The fan is not jammed (running at 6000rpm if I remember right) and the air vents are perfectly fine, since even when I remove the bottom cover, the temperatures stays the same.

I don't plan on replacing the fan or buy anything. I was just wondering if it was a manufacturing problem.

I have several USB coolers that go under a laptop since I am often demanding 110% for long periods. Room temp is usually 78-80F. Have one HP that was running 110F exit tem from the vent. Blew out all of the dust and added a undeneath stand/fan aand is now under 100F. I am something of a maniac abour running things cool.

DaoHeng

sorry, but you are talking with farenheigt (?) while I'm sitting here with 100 degrees celcius

Then you have a problem, am surprised things don't melt at 100C (212F)

Dao, I researched your problem, and I am surprised at how many people believe that it is physically possible to hit 100C on a laptop. They advise you to buy a cooler. make sure you don't have it set on a blanket, or take it to a repair shop.

 

And some, including me, believe that your sensors are way off. Most laptops will shut down at 65C. Some defective sensors will report that a computer is starting up at 62C. But at 100C, your laptop would have too many melted parts to function. That doesn't mean that you aren't overheating at a lower temperature, though, and I advise you to take it to a shop and explain your problem.

Hey, 

I forgot to say that my sensors are off, but by ~+7 degrees. I have a monitoring/throttling software called "Throttlestop" (It's what I use to ensure not overheating to the point to a shutdown. I know that my sensors are not off by 50* since when I put my computer to sleep for an hour and start it up, it shows 35* and when i'm gaming, 90* (those are celcius temps) You also have to remember that the easiest plastic to melt has a melting point of 130 degrees (polyethelyne) and metal used in integrated circuits' melting point is averaging the 300*.

When you say that most laptops shuts down when reaching 65*, you must be reffering to very old laptops or more or less old tower computers. My sources are from Intel and Nvidia themselves:

"Table 5-2.

And never did I say that it could withstant 100* with ease. My point is that whenever my CPU reaches 85* It shuts down.
