Acer 5739G - High Temperatures

Hi guys, I found this website whilst looking for people with the same problem as me, but could not find a proper working solution.

I bought my Acer 5739G in 2009 with Windows Vista Home Premium 32 bit and the first thing I did was a complete backup, a complete format and installed Windows 7 Ultimate 64 bit. Although I had a few problems, I managed to get all the drivers working and all the Acer software too even when they were not listed on Acer website.

The first few months everything went fine, I played graphics demanding games like Sims 3 and Battle for the Middle Earth 2 at highest values and there were no problems at all.

But everything changed a few months ago. The computer started to heat up a lot. I played the same games for like 15 minutes, and the computer was so hot it turned off automatically. Playing Mass Effect 1, CPU tempeture went from 50º to 90º in a couple of minutes. Not only the CPU temperature, but all the tempetures I measured with software like Speccy and Speedfan! I updated the BIOS to the latest version, the nVidia graphics to the latest version also, I opened the laptop and cleaned the fan, and I even changed the thermal paste on the CPU but no change at all!

It is really frustating not knowing exactly what made the computer went wrong from one day to another, hope any of you guys out there can give a hand with some advice.

Thanks in advance.

Edit: I didn't read your story which says more than the pictures.

Can we assume your fan is in fact spinning, and not making any odd noises?

If so, then you could have a bad heatpipe - heatpipes have liquid inside which is vaporized even at room temperature by use of a vacuum. So if its punctured it will stop working.

On the other hand, a lot can go wrong when repasting. You should defintiely take a 2nd try. Its easy to use too much paste.
It looks like your GPU temps are good.

Keep in mind your chipset, which appears to be at 88c is probably the CPU looking chip soldered to your motherboard at the end of the heatpipe next to the CPU. I think its covered in a thermal pad. You DON'T need paste on this.

If you've already put paste on the chipset, then you might want to clean it off and find a new thermal pad, otherwise it will be even better to replace it with a copper shim.

P. S. Are the high temperatures also causing your OS to change languages?
This could be bad news.

Thanks for the response. The fan just kicks out when reaching high temperatures like 80º, but it reaches that temperature in about 30 seconds of gaming. It does not sound to me like it has problems at all for moving.

The only thing I repasted was the CPU, and the temperatures were still the same as before. The problem has to be in the motherboard, the heatpipe or heatsink probably. It is there where the high temperature is, causing the laptop to turn off automatically for security reasons.

Sorry for the language, changed it to English on the first one so you guys could understand it better but forgot to change it on the second one.

Just had a look and read the 39 pages of the 5739G Owner's Lounge thread, very interesting stuff in there I must say. Seems I must get a new heatsink!
