Acer Aspire 8735G Overheating

[Hammersmithy]

My acer aspire 8735G keeps Overheating
i've already tried replacing the thermal gel with artic silver 5
i have cleaned out all the dust from inside and the fan is still working
and i make sure nothing is blocking the vent

but is still overheats >.>
i mean this laptop over heats and restarts when playing the sims 3

so has anyone got any suggestions?

I own the same model and I've never had this problem. Even with a X9100 CPU (45W TDP) and HD4670 (35WTDP) graphics card the temperature is still manageable. With the original configuration (T6600 CPU and GT240M GPU) the notebook never overheated.
What's your configuration?

I have the same Notebook and i have replaced the CPU to T9600. I have no problems. Does the HD4670 work in the notebook ?

The HD4670 works pretty ok and it doesn't heat up that much. With my X9100 OCed to 3.5GHz the system hits the 105 degrees limit and shuts down while playing games if I don't lift it about 2 inches from the table. If I run the CPU at 2.2GHz (T6600 frequency) or even at 3.06GHz (stock frequency) the system reaches about 90 degrees but it is stable.
In idle, the graphic card stays at about 40-45 degrees.
The only problem I have encountered while using the HD4670 is that with my card (I don't know from what notebook it was taken. I suppose it's not a general issue with this card in the 8735G) the VGA output is routed to the graphic's card DVI output so it doesn't work.

Thank you. Do you know anyone who replaced the GPU to a GTS 250m ?
The acer support says to me that the GT 240m the only card for the notebook is and the max. CPU t9600. But thats wrong I can see on your example.

I used (for a short time) an AMD HD6750M. It produces less heat than the HD4670 as far as I tested it and it's faster. The problem was that I had no video output on the internal display. It worked fine on VGA though. I am trying to solve this problem but so far I haven't got any solution.
The guys here on the forum advised me to go for the HD6750M instead of the GTS 250M when, just like you, I was looking for a cheap GTS for upgrade. They say that the HD6770M is twice as fast as the GTS so it's worth it.

The HD6750 would be a good upgrade for this laptop.But if the 6750 doesn't work,would the GTS 250M work with this notebook ?

The HD6750/6770 does work on this notebook. It's just a matter of getting the outputs of the graphics card routed to the correct connector. This as far as I know is a matter of software (SBIOS and/or VBIOS). If I manage to get this thing working I'll let you know.
I don't know about the GTS 250m. Better ask NetRoller or Meaker. They told me that the GTS 250m generates even more heat than the HD4670. At least for this reason (less heat than the HD4670), even though the internal display isn't (currently) working, the HD6750M is a better choice IMO.

I think the GTX 260m would work in this notebook. Or a 5870 if you could figure out the cooling.

Both of which are MXM-B, I suppose... I won't stress the motherboard that much. And a 120W power adapter is a must.
How much would each of them cost?
