Acer 5820TG big temp issue

Hello again!

I've decided to sell my notebook but I have to solve the temp issue before the buyer gets it.

First of all, the notebook specs:
- i5 460M 2.5Ghz (tb to 2.8GHz)
- 4GB RAM DDR3
- HDD 640GB
- Ati Radeon 5650 1GB (550/800)

Some temp screens (after 5 minutes of Crysis 2):

Look at the CPU and GPU temps. Even on IDLE, they are really high.
PS: GPU Overclock (700/1000) - 103 C = 217.4 F (can someone confirm that it is really strange - a significant overclock that increases the temperature by 2 Celsius ?

Even with ThrottleStop, the CPU cant reach turboboost frequency (it always stucks at 105C)

I have disassembled it more than 5 times, changed the thermal compound (Arctic Silver 5 and Arctic MX-4), cleaned it completely, but no changes (the temps are exactly the same). I think the heatsink is working well because the copper parts reachs about 50+ Celsius (122 F), and the air flow is warm. I reinstalled the OS, the lastest drivers, but no changes.

I guess the issue started to happen months after I adquired this notebook, because I was abble to play NFS Hot Pursuit with Full Settings and Stable 60FPS, but suddenly, after months, it started to get poor performance, giving about 25FPS (even with ThrottleStop). Shift 2 and some other games have the same problem.

Im trying to avoid the technical support because here in Brazil it sucks a lot (and it is really expensive).
Someone knows where is the thermal sensor situated? I was going to replace the heatsink, but I dont want to waste more money on that. How could I fix that ?

Thanks

 

Sounds strange, - it might be hardware-related since it could play NFS with no problems at all!

But here is my humble suggestions:
Have you tried to install the stock-driver for your ATI 5650 (or download the latest one from Acers website)? It might help. You could also consider buying a cooler that you can put beneath your laptop.

Kinds regards,

Thanks for the reply.
I installed the driver pack from Acer website, and updated from AMD website.
I forgot to mention that Im using a cooler pad - thermaltake massive 23lx.

Im afraid that it is harware issue (thermal sensor problem) or heatsink issue.

Thanks

 

It looks like a dust-issue to me.
Open the laptop- clean the inside of the radiator and while you're at it you might as well apply new thermal paste.

 

Thanks for the reply.

No. Im certainly sure that it is not dust issue. Like I said on the first post, Ive disassembled the notebook more that 5 times, and all of them I cleaned the radiator and all the air flow gaps. And I applied 2 types of thermal paste, and both didnt change the temp (I have applied well, not too much, not too little .They really worked on my desktop PC ).

Thanks

 

What's the ambient temperature?
Did you bend the heatpipe at any point?

 

The ambient temp is about 25C.
I didnt bend the headpipe, also have never heard about bending the headpipe. How does it work? XD

 

It doesn't work- heatpipes contain liquid that evaporates- if you bend a heatpipe too much it might crack and without the liquid inside it's no longer a heatpipe- just a copper tube.
If you haven't done so it should be OK but I'm running out of ideas...
